My mate Steve from LEJOG came over for the day yesterday and we did a 48 mile ride (using my new road bike) around North Bucks, via Quainton and having lunch at Great Horwood. We did 36 miles before lunch quite easily with the wind behind us. Cycling back after lunch was much harder with a headwind and feeling tired after being tempted to have a pint in the pub. I should have stuck to orange juice. We averaged 14.5 mph.
I've been using the road bike for commuting lately with panniers attached, but have decided to switch back to my hybrid as I prefer straight handlebars in traffic, and will keep the road bike for weekend spins.
