I have been running now for a year. My legs ached so much when I did C25K that I had to treat them by lying in bed with my electric blanket on full. I can't imagine using ice, I like warmth! I rested them on rest days too just to recover and I am so thankful they carried me through to graduation. Now I run three times a week still but I find they can cope with two 5k plus a 10k and still happy to move on rest days. I have tried step aerobics with Jenny Ford and Indoor walking with Leslie Sansome and even cycling - and of course taking my little friend Max the Jack Russell for a walk. Despite the warnings that running will ruin my knees and even "the man who invented jogging died young" I think the discovery of running has been the best thing and if I die running, it will be with a smile on my face!
