I'm going to have to put starting on hold. I've been doing trial jogs the last few days, I walk the dog every morning, and my left knee just can't handle it yet. I injured it a couple of months ago and it's still not 100%, I get a lot of pain during the jogs so I think I need to work on strengthening it more before starting. Losing a few kilo's will help take the pressure off it too. I'll keep walking and keep watching this thread - good luck
