Went to the gym for a ride on an exercise bike. I was looking to swim as well, but due to the heat every man and his dog was in the pool. To save having a head-on in the lane I just used the gym instead.
Used a conventional exercise bike this time. Used the same programs as on Saturday.
Which meant a 7 minute warmup in which I covered 2.3ks.
I then did the 20 minute program which throws in an occassional hill, with a 2 minute warm down after that. I covered 9ks during the 22minutes.
I wouldn't have a clue if any of that is good or bad. But it certainly works the legs without getting any impact on the stress fractures. Which is why I am doing this.
