A half hour and two laps, on top of 4 slow laps for charity, two warm up laps and a cool down one. 2.7 kms each and the ride to the track and home = 50+ kms. Not that big an effort, but after getting showered up, eating a huge and beautiful brunch at a friends and going home to a nap I am still just toasted.
Tour de France live at 10pm. Hopefully I'll have some energy to do a few chores tomorrow. At least the dog is getting some quality time. He just loves naps.
