TFL's London Cycle Challenge

Nah turbo trainers, static bikes, rollers etc all count I reckon because otherwise it excludes groups who enjoy cycling but can't cycle on the road for legal reasons - like my mate Ben who is blind who ocassionally does a bit of tandem stuff with me but otherwwise isn't able to go on the road.

Interesting point, but Rolla miles should count for half as there's no wind resistance and mostly no rolling resistance...

My mum is probably joining the team!
