nice vid (flying lap) gloves need a wash haha! :-P. wonder what the camera did for the aerodynamics of his Casco??.
I'm suprised at the wind-up, though. Looks like an extra lap, if my brain wasn't boggled by the lights and crowd ;-)

I foresee a very late night of reading for myself, too.

Have only had a look at one or two links - all fascinating so far. (We can now all conclusively say that wind-tunnel tests have shown shaved legs have a statistically significant aerodynamic .... difference from hairy legs)

LOL, the first thing that caught my attention too... Gotta run that by my wife and see if she'll still stay w me if I shaved my legs.

Seriously a 50-82 second difference over 40km is significant. I'd say similar would apply for hairy arms too.

For sure ^ And hairy arms have the added (?) factor of being perpendicular to the airflow - so to my mind, a possibly amplifying the resistance effect? (like cells in series, vs cells in parallel). but my reasoning might be flawed.

Great find carleton, thanks for posting!

I'm bummed I didn't realize Nate and Missy were at the Berlin Sixdays otherwise I might have figured a way to go. I saw them at the LAVRA a few times and they are great people.

Missy's smile when she podiums is priceless https://www.youtube.com/watch?v=B6MqpBWNGXE

Not sure how or why I came across this the other day (I don't hang out on lifting forums at all) but thought this was so applicable to cycling, even track

The 80/20 rule
The 80/20 Rule for Lifting - Bodybuilding.com Forums

The idea is that 20% of the details will get you 80% of your results. So the basics, eating right, sleeping well, riding hard, is 20% of the theory of training, but get you 80% of your results. While all the details like how much to eat, how long are intervals, what time should I train, all the non-sense, makes up for only 20% (generally speaking of course).

I love it, and think its such a good message. People get hung up on training plan details, diets, periodization, etc. If you just do the basics, eat well, sleep well, ride hard, you will get most of the way there and have a lot more fun doing it.


Its not to say ignore the fine details, especially as you get to the top of your game. But people new to the sport, really need to just worry about the 20% for a while and its all they need to progress and enjoy the sport.

People new to the sport need all the help they can get, not a platitude. Racing, like it or not, is a 100% sport. Not 80%, though too many people treat it as such.

People end up in hospitals (a lot) and even dead doing this.

The 80/20 "rule" is laughable because it assumes people have some brain implant that makes the "basics" already hardwired. Quick...what's eating right? Or riding hard? I mean every one will agree what those things are, right? Go over to the 41 and see how many different answers you get, and how much of it is completely stupid.

Too late tonight to link the relevant studies. But a vertical cylinder is far worse aerodynamically then a horizontal cylinder regardless of the surface...

I haven't taken as much interest in material aerodynamics so can't quote immediately, so I will need to look back over the various studies I linked recently again about the interaction of materials on the forearms. I am sure if it was proven to be faster, cyclists would already be shaving down like swimmers do before big meets.

Clock racers are already wearing long sleeve skinsuits for the aero advantage. Shaving your arms appears to be a cheaper method of acheiving a similar result.

People ending up dead? That sounds a bit extreme in response to eat well, sleep well, ride hard, and have some fun.

I'm a rider who has returned after decades of being away from the sport and I see a sport that has taken an very technical approach to training. Periodization? Power meters? Ketonics? This is all new to me. I understand if one is Pro or an Elite racer where fractions of a second make difference between a podium spot or packing up and going home early. For the 99% of us from the newbie (cat 5) to a regional racer (cat 2), I think the 80/20 sounds like a good idea, especially since that is what I am doing and I have no plans of ending up dead. Ride frequently, mix up hard rides with easy rides, go climb mountains or sprint against friends, don't eat too much in response to your training, and get enough sleep such that the alarm clock is not your enemy. This doesn't sound like a death sentence to me, but then again, I have no idea where to find the 41. I'm just having too much fun enjoying cycling.

Where in the linked post does it make that assumption?

Almost no one will disagree that eating whole foods and avoiding junk/processed food is basic in "eating right". Also, how many times has advice been given in this exact forum that when first starting, just riding around will show significant improvement amongst beginners. How many people here state that track time is very important in progression.

You're reinforcing the point of the post when you talk about asking other forum posters for abstract yet personally nuanced approach to eating, sleeping etc.

That post is spot on. Thanks @gtrob for sharing.

You've been spending to much time in the 41, and that thread is exactly what some people there need (I wouldnt dare post it there as it will just digress into a thread about **** or obama likely)

So to your point a newbie rider should be worried about protein amounts, exact intervals durations, cassette choices for racing, and their body weight down to the gram? Thats the 80% that gets you the 20%. People new to the sport dont need ALL the help they can get, as most of the help can't be given to them yet. Would you teach someone who doesn't even know pack riding skills race tactics? Why not, they need all the help right! No, you ignore the plethora of fine details (80%) and teach them the core skills first (20%).

I think you are just reading it wrong, its not 'ignore 4/5ths of what everyone tells you', its dont sweat the details. If the person is to dumb to realize what core common sense advice is and what is minutia detail, I guess thats what cycling coaches were invented for

I think there's something to this.

Someone I know is returning to cycling after a 6-year hiatus. She had maybe a season and a half before that hiatus. During the hiatus, she still rode her bike regularly but mostly as a commuter. And, she just had an extremely full season back in race mode - tons of crits, track, and cx. She had a killer season - hard at first, but just constant gains in fitness. It's not because she's training with great precision or anything - it's just the regularity of racing and training provides this huge, initial platform for adaptation.

I've seen this happen with a lot of newbies, too - especially ones who are already athletic. Riders like this get gains from just doing what they do. Simply riding and racing a lot leads to the greatest gains. Getting more involved is great, but it's not necessary to make those initial gains.

I wouldn't describe the rule as 80/20, but there is something to be said for the fact that big, intitial gains can come simply. I guess the important part is knowing that there's a point at which that will change, and continuing to make gains is going to get a lot harder.

Specialized did a few 'hairy' tests recently, not sure I remember seeing arms though. They did test beards however and found no slow down with even a pretty thick beard. Where the hairy legs showed to be a pretty large effect.

As Dalai pointed out before, skin is always slower than fabric, and to that end I would guess hair is slower than skin. I guess it just depends how monkey-like your arms are. Of course, you can cover them up.

FYI: They say that road bikes are like track bikes but you can magically change the cog by flipping a switch. I don't think anyone has ever seen one in person, though. I think it's a myth. It's impossible to do for so many reasons. And get this...they say they ride them for HOURS...LOL. I want to smoke what they are smoking
