I'm about to leave the brewery to head for Sturbridge & the Pan Mass Challenge start, and had a spare moment. I decided to spend it doing some math & remembered why I don't like math in the first place. Here's what I've calculated:

PMC=192 miles
192 miles = 1,013,760 ft = 337,920 yards= 308,994 meters.
FG road bike at 42*16= 69 gear inches, or 5.5 m/pedal revolution.
308,994 meters/5.5 meters per stroke = 56,180.734 pedal strokes this weekend.

Not counting side trips to the pub. ;D

I'll let you know Monday if my math was correct...

D@mn!! I lost count somewhere in Wrentham. Just can't stick to a plan.

Here's a stat for those interested: according to the computer we hit a max speed of 37.4 on one of the downhills. With a 69 inch gear, that calculates out to 182.4 rpm. Yikes. :-[

182.4 RPM! That is some crazy pedaling. Were there many fixed gear folks riding?

I hear the PMC raised 42 million for the Jimmy Fund and cancer research.

Jaime: this means that each of your pedal stokes helped to raise $0.73. Great job!

As the other half of the "we" on the fixed gear pmc ride I can vouch that 182.4 rpm's is pretty sketchy. We were dropping people on the climb & they would shoot past us downhill. One guy flew past us, sat up & braked so that he was riding next to us at the bottom of the hill and said, "you guys are going over thirty miles an hour on fixies, you're nuts".

It was also a nice pat on the back when I was introduced to someone in Bourne who was told that we were riding fixed and the guy said, "oh man, I heard about you guys".

What do you say Jaime, next year on unicycles?

I remember Jaime riding his fixie on one of the hillier CRW centuries last summer. On one of the longer downhills he finally max'ed his spin and things got ugly. Basically his bike started hopping and lurching side to side once his legs couldn't match the cadence -- all this while going around 40mph!

I was on my SS road bike (merrily coasting along, not a worry in the world), and I remember thinking that it probably wasn't such a good idea riding next to him on the downhills.

;D
