One Hour on the Bike...

Copyright - Chain Reaction Cycles
Ok, just for the record they left out the part about the rider and machine becoming one... powering each other toward a common goal. Ice Cream!

But seriously... while on the bike I think the body eventually finds its “perfect rhythm”.  Each of the vital internal systems comes into sync… freeing the brain from the distraction of having to mange them individually... like little children competing for attention.

And as this happens you begin to enter a special place… a place where your mind is now freed to wander in different directions and engage in the kind of creative, reflective and philosophical thinking that is necessary to live a healthy, happy and rewarding life.

And on my opinion… this is the true value of exercise.

Jackson Horner - Coach, Gentleman and Friend.

Ever have one of those moments when a song you h-a-t-e suddenly pops up and you can't get it out of your head? I did a pretty tough... pretty fast paced hill workout today and during the last half (when I was starting to bonk)... I started hearing two voices running thru my mind... much like one of those songs.

The first was my old SCAHS track coach yelling "Work the hills Mengle -- work the hills!". That was one of Jackson Horner's favorites. And to this day I know he was right in pushing us on those hills... because that is where races are won and lost. Remember last year's Tour? (Forget the mechanical... forget Alberto's bad behavior... the race was "won"... and "lost" on a hill!).

The other voice was Penn State and US Olympic Team track coach Harry Groves... "You can't teach guts!"... as he reminded me many times last summer. For anyone who knows Harry this would of course be one of his less "colorful" quotes. In fact there is a whole website dedicated to Harry and his famous (and unedited) quotes and comments on anything from running to politics.

Anyway... like a blast from the past I could hear both of them like they were right there beside me. And I was thankful I couldn't get their voices out of my head because I found myself standing in the pedals and powering up the hills with renewed vigor and determination. Not wanting to let them down... not wanting to let myself down.

As a runner I owe much of my (moderate) success to both these outstanding and dedicated individuals. And it appears that even though I'm not running much now... and have traded running shoes for rubber tires and gears... they still have much to offer in terms of advice, inspiration and motivation. These could be my two favorite quotes of all time and of course cover much more than running, cycling or getting through a tough workout.

Thanks and Rest in Peace Coach Horner.

HRM1 vs MioLink...

This graph is a supplement to a comment I left on DCRainmaker.com concerning my results using the new MioLink optical heart rate sensor from Mio Global.

My testing was done using a Garmin HRM-11 chest strap (the original old style supplied with the Forerunner series units) paired with a Garmin Edge 500.  The MioLink was paired with the TrainerRoad indoor cycling application running on a PC.  Both tracks were recorded using the ANT+ protocol.

At the beginning of the activity the MioLink was intentionally moved on my wrist (Link was worn on left wrist) to create a "break" in the HR track for further positive identification of the MioLink's track.  As the graph above shows... after about one minute the tracks began to match fairly well and continued to do so throughout the activity.

Overall I would consider the results to be very respectable if you are using the HRM1 as the "standard" the MioLink should match.  Critical users will not that certainly, it’s not a perfect fit.

But personally I really believe power is the ultimate precision training tool anyway.  Heart rate is only a rough indicator of how hard I’m working because there are so many variables that can affect it. But power is power, whether you like the numbers on any given day or not.

However as a supplement to power (or when riding a bike/wo a meter) I think overall the Link would appear to do a decent job. Over the course of a long ride I really don’t feel the need for second to second correlation of heart rate with another device.

I think ultimately it would boil down to a decision about whether you want to wear the strap or not. And there are probably times I still would… like for longer events. If anything battery life is the biggest reservation I have about using the Link.

Results...

Results!

After about 2 months of using Trainer Road and 5 weeks of following one of their training plans, I believe I am seeing some truly measurable results.

The graph at left shows 3 rides of the famous (or infamous) Sufferfest video ISLAGIATT.  My latest ride was yesterday and is represented by the green line(s).  As you can see, the bold green line (which represents average power throughout the ride), is consistently higher than the other two and by the end of the ride my average power was almost 9 watts or 5% higher than on the other 2 rides.

At "first glance" you might think a 5% improvement is pretty minimal, but over the course of a two hour ride that's an extra 1.1 miles on my total distance!  Not that I race much, but in a business where wins are sometimes measured in centimeters and fractions of a second that's huge!

Now granted it's indoor training and not on the road.  And there are some variables that could affect my (absolute) power readings.  But as I have noted in a previous post, I have found the results produced by Trainer Road to be very consistent.  Each time I ride I use the same gear ratio (39/17)@90 rpm to check my power right after warming up and then again during my cool down... and it's always the same within +/- 1 watt.  You can't ask for better than that.

So I believe the results to date to be real and would highly recommend the Trainer Road system and the Sufferfest videos to anyone looking to improve their riding results this season!

Bon Voyage Sufferlandria...

It's with a heavy heart and burning quads that I leave the country of Sufferlandria today. Passport stamped and '85 Yugo rental car returned, I prepare to cross the border back to what's considered by most to be "civilization". Yet I've developed a fondness for this interesting country. I suspect I will have to return again this time next year to revel in it's charm & endure unspeakable pain, misery & agony. Bon Voyage for now... and as they would say when you come face to face with a rabbit with sharp pointy teeth... RUN AWAY!

Tour of Sufferlandria - Stage 6 Report



Tour of Sufferlandria Stage 6 - Done!To view the suffering click here

And just in time because at the end of the third interval, I began to sense a soft, warm glow begin to crack the gloom of my "Very Dark Place". I was feeling all warm and fuzzy inside & thinking, "This isn't so bad, I expected much worse".

Turns out the warm glow was from Sufferlandrian lava, flowing toward me like a tidal wave about to engulf another dropped rider. Worse yet, riding the crest of the lava wave was a Minion on a surf board, stick in hand & cursing at me from behind to increase the suffering or meet my well deserved fate.

Thankfully just as I was about to feel the crack of the Minion's stick on my back and the heat of the lava was about to melt my rear tire, I found some "inspired power" and rang a new 2 minute watt-based PR out of my suffering, wretched body.

Now, time for some recovery for tomorrow's stage. Bring on some of that hearty Suffererlandrian Ale & any left-over porridge from this mornings breakfast.

First Bike...

Heading out
Wow. This faded Kodachrome slide brings back memories.  Taking off for a spin on my first bike... complete with fenders, rack and headlight.

Used it to ride to school and deliver newspapers on the weekend.  How times have changed.

Now It All Makes Sense...

“The chances are great that the best potential athlete in the world is an overweight, sedentary smoker. Right now sitting in front of the television somewhere is this person born to be the world champion in cycling and to dominate the sport as no one else ever has…

The problem is that he never had the opportunity to discover his ability.”

-          Joe Friel, author of the “Cyclists Training Bible”.

Wow, as we used to say back in the 70’s when I was a kid… “That’s heavy man”.  A scary thought, but I have no doubt it’s completely true.  And it makes me that much more grateful and appreciative of the fact that I had the honor to be coached by people like Jackson Horner (State College Area HS), and in later years Harry Groves (Penn State) throughout my “career” as a middle-distance runner.

Now even though I was actually a pretty decent runner it was clear I was never going to the Olympics… or even going to consistently win all the “Big Races” in my own backyard.  Yet these guys both spent countless hours and expended considerable energy working with me and my team-mates to bring out the best in us.  To allow us to “Be all we could be”.

And no doubt inspired by Jack and Harry a few of my former teammates have gone on to become coaches themselves.  Bill Kvashay and Dave Felice both work with high school kids in northeastern and central Pennsylvania.  Bill has produced some very respectable runners at Lake Lehman HS and Dave continues to work in his hometown with many promising kids at State College.

However, despite all I owe my coaches and teammates… even more instrumental to my (modest) success was the constant and unwavering support of my parents and family.  At the time, I’m sure I didn’t really realize, understand or fully appreciate the amount of time, energy and resources they put into supporting my running.  But without them I couldn't have taken that first step onto the track.  I can only hope all the late night pick-ups at practice; weekends given-up to attend meets and occasional “breaks-in-stride” both on and off the track were worth it for them.  It was (and still is) to me.

And now circling back to coach Friel’s observation…


Pardon the pun… but a few years ago I “shifted gears” from running about 1000 miles a year to cycling 7000.  On more than one occasion various people have accused me of being crazy, OCD or even worse to ride as many miles, spend as many hours in the saddle and push myself as hard as I do each year.  And to some extent they might even be the tiniest bit right. But I’d rather think it as my way of honoring the family and coaches that showed an interest in allowing me to discover my abilities early on so I didn’t have to wonder if I was “That guy on the couch”.

Felt Z-85 Long Term Review...




Date Reviewed: April 18, 2013

Strengths:    Value, comfort, performance.

Weaknesses:    Paint (USA - 2012 version ). OEM Brakes.

One of 2 Felt bikes in my assortment and arguably the one I like the most based on 9500 miles of riding experience with this bike during the past 2.5 years. This was my first Felt bike (also recently purchased an F4). 

Comfortable and predictable ride, good choice of components out of the box (2012 version anyway). Straight off the sales floor this is a great everyday training bike for the Cat 3-4 racer or the perfect tool for the weekend group rider. The OE build offers both great performance and solid value for the money. Can't add much more to the previous reviews other than to reinforce the positive and say you definitely need to upgrade the brakes. Immediately if you live in hill country.

For someone looking for a long term relationship with this bike note that it is totally worth upgrading the group-set (or individual components) as the stock 105 components wear out. The frame is worthy, even if others might scoff at the idea of putting higher level components on an alloy "recreational" frame.

I've upgraded my saddle to a Prologo Skratch Pro, the crank to a full size Ultegra 6601, the front and rear mech's to Ultegra 6600 and my wheels to Ksyrium Equipe (which came from my F4, but which wears Cosmic Carbones). I changed out the brakes to 105 very soon after initial purchase and started riding Conti GP4000s when the OE Vittoria Rubino's wore out. Built up with these components the bike is a very solid trainer or A level group ride or fondo bike.


The only issue I've had is with the paint bubbling-up around the breather holes in the seat stays, seat post clamp area and bottle cage bosses. A little irritating since I basically put the bike thru a pro-level cleaning after every ride, but not structural and I suspect easily repaired. In fact it probably says a lot about how much I like this bike that I am considering investing in a custom paint scheme in the near future.

Bottom line:  You could do a lot worse and might be hard pressed to do better!

Can Trainer Road and the CycleOps Fluid 2 Trainer Produce Consistent Results?...

Test-1 @ 80 rpm

Test-1 @ 85 rpm (dropping 2 cogs)
Test-2 @ 80 rpm
So one of the biggest questions about Trainer Road (and other similar programs) that produce a virtual power is "Are the numbers accurate?" or "Can they produce repeatable results?"

My somewhat non-scientific testing done today and seen in the charts to the left would seem to indicate that the results are repeatable enough to allow use of the program as a reliable training tool.

Are the numbers the same as you would get using a $1000 to $1500 power meter?  Probably not.  But they do match up pretty well to the numbers I got last year riding on the CompuTrainer, a system which sells for $1600 plus and that doesn't include all the software necessary to graph results and create workouts.  My testing was done by warming up the trainer for 5 minutes.  Then spinning for a minute at as consistent a cadence as humanly possible.

Test-2 @ 85 rpm (dropping 2 cogs)
One minute tests were done at 80 rpm and then dropping 2 cogs and spinning for one minute at 85 rpm.  Then the bike was removed completely  from the trainer, a bit of air was let out of the rear tire and the resistance unit backed off from it's clutch locked tire tension position.

The tire was then aired up again to 100 psi, the bike placed in the trainer and locked into the same position.  The resistance unit was then tightened until the clutch mechanism slipped one notch indicating proper tension on the tire.  The second set of tests was then run.

As you can see from the charts, the results are very similar, accurate to a watt or two at the same cadence.  That's close enough that I think it safe to say you can use Trainer Road and similar programs as a useful (if not completely accurate) training tool.  And given the cost it's a bargain for the cyclist that would like to train with power on occasion but who isn't ready to take the $1500 plunge into crank or pedal based power metering.

As I spend more time using the program I will post updates, so stay tuned :-)

(For those interested: Testing was done using a Mavic Ksyrium Equipe wheel with a CycleOps Trainer tire inflated to 100psi, CycleOps Fluid 2 trainer with slip clutch tension adjustment and Garmin GSC-10 speed/cadence sensor.  The test file was then exported from Trainer Road and imported to Strava for "analysis").

Trainer Road Update...

So here's yesterday's workout from TrainerRoad (www.trainerroad.com).

After about a week of using it I'm starting to understand the program a little better and find it loaded with potential.

Workouts can be scaled up or down depending on the intensity you want and the on screen coaching works pretty well.  For example in the 4 tempo blocks shown here the coaching prompts tell you what goal is for cadence in each block, when to work out-of-saddle and what to watch for in terms of form (knees straight up and down, light on the pedals, kick forward over the top of the pedal stroke, etc.).

So I think this will be my trainer software of choice for when I'm stuck indoors this season.  Now I just need to figure out how to best work with video to keep longer workouts entertaining.

Playing with Trainer Road...

VQC Race Day DVD
Despite the fact that I'm trying to ride outside as much as possible this winter the reality is that there will be days where it just make sense to stay off icy roads.

Winter Riding Tips...

Well, inevitably, it appears the cold weather riding season has arrived! But don’t let “Old Man Winter” drive you off the road and into the pain-cave just yet. It’s worth at least putting up a fight before you retreat indoors to crank your way through countless hours of M*A*S*H re-runs, music you don’t really like (but which has a beat that matches your cadence) and riding hundreds of miles without going anywhere. With proper planning and preperation riding outside through most of winter can be both fun and invigorating. Not to mention, you get significant bragging rights!

So here are a few tips for dealing with winter. With luck you might even ride right through it and not even notice. (Well, probably not but it sounds good):-)

1) Heavy sweating and the pursuit of Strava PR’s are for summertime. In winter you need to be careful NOT to break (at least too much) a full sweat. It’s a simple equation. Wet, sweaty clothing =’s a cold rider! Use synthetic fiber base and insulation layers. For your outer-most layer choose soft-shell fabrics which breathe much better than waterproof ones. Moderate your speed when necessary to stay as dry as possible. Let me repeat, winter is not the time to work up a sweat. If you experience a puncture or mechanical and need to spend time off the bike fixing it, you’re not producing the necessary body heat to stay warm while you’re doing it. Cold wet clothing is guaranteed to pull heat away from you in less time than it takes me to polish off a double espresso.

2) Mechanicals and flats are potentially, seriously serious issues when it’s 15 degrees out. Have your LBS tune and check you bike if you plan on training or commuting outside through the winter. Make absolutely sure they check your cables and housing because a broken cable means no shifting or no braking depending on which cable is broken. Neither scenario is good and both are hard if not impossible to fix on the road.

3) Change over to “reinforced” tires like the Continental 4-Season Gatorskin's. There is less road surface available in the winter so that means there’s a greater chance of running over broken glass & trash or hitting potholes and/or other road damage from plowing. They’re no guarantee… but winter roads are no place for lightweight racing tires or tubulars.

4) Choose your routes intelligently. Rather than doing a 20 to 40 mile “in and out”... choose to do 2 or 3 shorter loops that add up to your total planned distance. That way if anything bad does happen, you’re not 20 miles from home without a friend. Keep in mind, bike shoes don’t hike well and to me doing laps outside still beats working hard and going nowhere inside. Pretend you doing a crit if that helps and try to improve your time on each lap… without working up a sweat of course.

5) Good lighting is essential to see where you’re going as well as to be seen. There’s lots of dark out there this time of year. Make sure you charge batteries daily, preferably overnight. The manufacturer’s stated 2.5 hour burn time (likely tested & established in a 70 degree room) will probably not be accurate for riding outside when its 20. Batteries lose capacity when it’s cold and a dead battery equals no light which can be downright inconvenient, extremely dangerous and definitely illegal. Carry a small headlamp too. It’s much easier to use than your bike light when changing a flat or doing other on-the-road chores.

6) Purchase and use a mirror. Hats, balaclavas and helmet covers make it hard to hear what might be sneaking up behind you. This is especially important because you probably have less road surface available to avoid traffic coming in either direction during the winter months.

7) Chemical hand and toe warmers can be your best friend. The hard-men riding the Belgian classics might disagree… but I’m not one of them and never will be. Hand warmers placed in your gloves and under insulated booties can turn a cold day into a good day. I know, I’m a wimp and I use them regularly.

8) A well fitting WindStopper balaclava (not to be confused with baklava, which can be a welcome pick-me-up)is essential gear. A balaclava very effectively seals the vulnerable gap between your face and your shoulders when tucked under the collar of your riding jacket. Closing that gap makes a huge difference in overall warmth, especially when you’re getting low and aero and huge volumes of cold air would otherwise be getting funneled right down the front of your chest by the collar.

9) Pay attention to nutrition and hydration. You need to eat and drink & maybe even more so in winter than summer. Carry cash and plan on stopping at the local convenience store for water, there’s no way around it on longer rides. (And trust me… cash is more welcome than a debit card when only buying a 99 cent bottle of water). Choose foods that will not freeze into tooth breaking chunks of ice. Gels and ShotBloks work well, although they’re not the best thing for your teeth either according to my dentist. Brush afterwards.

10) Finally, don’t let the cold freeze that part of your brain where “Good Common Sense” lives. Everyone is different and has different responses to cold. Experiment safely, establish your comfort zone and learn when you need to pull the plug and jump on the trainer. For some this might be 30 degrees, for others 10 and for a rare few 0. And I know some for who it’s 70 but we're not even going to talk about them because they’re not reading this anyway :-)

Vittoria Zaffiro...

Can't make up my mind about these tires. Seem slow to go... but once you get them rolling they're almost fast. Quiet, soft ride. Stable and confidence inspiring. Price is right.
