Returning to the tunnel.

The worlds biggest cycling vacuum cleaner

I've even written about how in retrospect many years later I didn't think my time spent at the tunnel was overly productive. So why in the world am I talking about going back?

Partially because I am hopeful that I have learned enough in the last 5 years to not make the same mistakes (new mistakes!) and also because I have some hope in working with Brian Stover and Heath Dotson at Aerocamp that we'll tease out some information I can apply. There is also a time sensitive matter in the back of my mind (the worlds worst kept secret) that, when it boils down to it, is part of what you are paying for going to the tunnel vs. track testing every time I get a chance to head down to Rock Hill. Convenience always costs premium.

I also have slightly different expectations out of the tunnel nowadays. It's not a cure all, or even the definitive way to a final position... it's just a tool.  Nice, clean air in the tunnel is not the same as the dirty turbulent air you find in the wild, but likewise, because of that same thing testing in the tunnel is much easier to get repeatable results. Give take and all that.

In 2012 I wanted to do EVERYTHING in a couple of hours... helmets, suits, positions... pretty much jack of all trades it. This time, I want to nail down a few things with multiple controls to make sure I leave with data I trust and can build off of. Things like helmets / skinsuits are low priority because it's pretty simple for me to test those myself. Instead, knowing the difference in positions (to compare with the metabolic cost / efficiency) is what I am after.

Is this

Better than this?

If it is, how much does it cost me in terms of watts I can produce. Which is better at different angles, does it change?

Obviously the top picture is more compact, and likely more aerodynamic (although sometimes you get surprised) but what if I can produce 20 more watts in the second picture? Is it THAT much more aero? These are questions that are important when trying to find every free watt.

I am excited for the opportunity to go back and work on things some more. Fit is always an evolution, at least for me, and this is just another step on the road to learning.

I'm scheduled for early March, of course I'll have a full write up!

Thanks so much for reading my randomness this week, it's been busy! (Tax returns and car sales = work work work!)
