Winter Training in RP, Saturdays

He's a skinny and fast antipodean?
Might be a little slower but wind can be a factor in RP. My highest speed in RP was 40.5 mph going down Sawyers Hill with dodgy brakes and a strong tailwind. Say he went anti clockwise with no traffic and took the two descents very fast, climbed the bumps at over 20mph (which is far from inconceiveable) and sprinted on the flats....

I know. He did my cyclefit.

The National 10mi record held by Wiggins is 17:58 @ 33mph/52.8kph but I don't know the course (I assume these records are set on fast flat courses but maybe I'm going wrong here?). So, Spence is only 6kph down on Wiggins around bumpy, turning RP, albeit on a shorter ride? Seems a bit like Chinese Whispers where each person that tells the story rounds down.. could just email him and ask him :)
