I might be in for next year. Arthritis caught up with me late last year, and for a time my running career looked like it was over. Between losing some weight, cross training, running on forgiving surfaces, a lot of vegetables, spices and herbs, I've been able to manage it to the point that I'm running 30 miles/week now. I can't run longer than a 10k on the road, though, without my joints complaining. I think I can squeeze another 15-20 lbs off, though, and I know based on experience that will make an enormous difference to my joint pain. If I get to that point I'll probably give MW another go. My son and his friends did the half this year.
