I like this very much, I need to get back on some form of Saturday morning group exercise (masters swim I think in this case rather than spinning) - however it is easier when I am "on vacation," in the sense that I've had three nights to catch up properly on sleep....
Anyway, did some good treadmill intervals first, then spin class.
Run: :31 with 10 x (1:00 @ 6.5mph, 1:30 walking recovery). Did first two too fast (7.0mph, 6.8mph) - it's supposed to be hard work but not overwhelming.
Need to change tube on back tire of bike for the triathlon, not looking forward to that but it must be done!.... (And will ride it around in the parking lot to make sure everything's functioning OK.)
