I got one the weekend before when me and the shadow went out for the pre club-run hour - it was -2° when I left, then after a failry sedate 19mph to Charlwood, me and Hasledene didn't stop, gave it plenty all the way back - I don't think the numbers on the powertap go high enough for the kind of wattage that man puts out on the flat and when we got on the hills I was taking over so it was a bit of an ill-advised thrash given the temparatures
Actually it wasn't from the ride I got sick, it was getting back to a hot stuffy office full of people who were already passing a seriuos infection around
Quickly developed into my usual bronchopneumonia, been off the bike for 2.5 weeks but went out yesterday and was interested to see that despite speeds bordering on a miserly 18mph, my heart rate had spent an hour in the 'racing' zone on my powertap - ie over 170
