Surely after 5 weeks, you are close to getting back?
Maybe you could try something like swimming? That has got to be the ultimate rehab sport. Even if you only really want to do running- you can't, so why not make the most of an opportunity. Try something new. There is always rowing, golf (if you can walk), weight training, yoga, etc. All of these can be modified to allow for your ankle. Probably best leave the trampolining and parachuting 'till you're better though ;)
This layoff doesn't have to be a 'bad' thing mate. It maybe the period where you realised how much you loved running, or perhaps where you discovered a sport which you had previously never considered.
Whatever happens, try not to be too down about it. Check out the forum and join in some threads. It will help keep your interest high.
Hope you come back to the fold soon, Nick :)
