Over the last 5 weeks or so I have been swimming 3-4x/week, going to the gym 1-2x/week, cycling on the stationary bike 2x/week and doing a bit of yoga.
I feel my overall fitness is pretty good and the injuries feel fine however I have been advised to give it another 4 weeks before running. Seems a bit excessive so I might slowly start running on the treadmill in 2 weeks time.
Hopefully a rest from running will prove to have been a good thing in the long run and all this crosstraining should help especially if I can keep some of it going once I get back running.
For the record I can now swim 800m reasonably comfortably although there is a massive potential improvement if I can cut out the gasping at the end of each length.
