Marathon for a superdog - Harbour Capital Marathon

Hey guys, When walking the dogs on Saturday I slipped and fell awkwardly, twisting my knee.? I don't think I've injured it badly, but it is still painful four days later, and with the marathon on Sunday, I'm not sure if I'll be able to run it without putting myself at risk of an even more serious injury. So, I've decided that I'll either walk this one (depending on how I feel closer to the time) or not do it, but I will?run the 5 Bridges Marathon on 18th July instead. http://capitalmultisportsrunwalks.co.nz/default. http://capitalmultisportsrunwalks.co.nz/default. Absolutely ironic - I took the weekend off army training so that I wouldn't get sick / injured before the marathon, and then go and hurt myself anyway.? The limp has gone, but it's still painful and I'm having trouble with steps and downhill slopes, so a 42km run in four days seems a bit of an unrealistic goal right now? :( Thank you again for all of you who have pitched in; this postponement?was not an easy decision to make, but I hope you understand!
