Second ride: Glebelands Open Space
I took the bike out for a real spin this evening, following a route marked out on the London Transport / London Cycling Campaign maps. The route was exactly 3 miles round trip, which I did in under 25 minutes.
The route took me downhill almost all the way to a large open field next to a woodland -- a place I didn't realize even existed -- and the route back was, um, uphill most of the way. I was fine until the very last, sharp incline (again, over railway tracks) -- and felt some pain (not much) in my arms and legs. This pain went away very quickly after getting off the bike.
