Road runners do aqua jogging when injured, so maybe you could try running down waterfalls. Just a thought

I sympathise with you, when I had an ankle op I was in a cast of some description for 8 weeks and had to get picked up and dropped off at work as well as being helped doing everything. Going to the shop was fun when I could finally get out on the crutches to buy some junk food, until I bought a bag of goodies and realised how difficult it was to carry a bag and use crutches at the same time. It's frustrating but necessary, good luck with the recovery
