I've just begun training for my first sprint tri and have been doing 3 cycling sessions a week on the stationary bike in the gym. I'm wondering how I can most usefully use these sessions.
At the moment I'm considering 2 60 minute sessions (one hills, one speed) and 1 90 minute session of intervals for endurance. When I get a real bike (asap) I'd then replace the 90 minute session with a real bike ride.
Does this sound sensible? Is it enough? Any advice? Thank you in advance!
