Did the low key ITT on Canada yesterday: they have a 'Merckx' division for riders with a regular road bike -- no aerobars, wheels, helmet, etc -- and you get to compare your time with the 'real' TT riders. I did the 10 miles in 26:06, which is 23mph average, and used the powertap, of course, to get some useful data. Hopefully I'll still be riding next year and can compare my data with this TT.
Here's the deets:
- 321 watts average
- 26:06 @ 23 mph.
- 12 minutes on the 'downhill' to the turnaround at 25 mph and 324 watts.
- 14 minutes on the 'uphill' from the turnaround at 21.5 mph and 318 watts.
If you look at the power file, the race was really a series of intervals -- about 350 watts on the rising sections, then below 300 on the slight downhills. I managed to hold the pace fairly well into the second half, but it seems like a better time can be achieved by holding back on the first half, and then nailing it on the 'uphill' to the finish. The math says I'd have to do the first half at 26 mph to shave 30 seconds off my time during the first half, but only 22.2 on the second half to get the same time savings. Given that air resistance is proportional to speed squared, it's more energy efficient to increase your power output somewhat on the second half. Something to keep in mind for next time.
