Looking for some advice on how to handle the last 3.5 weeks of my London marathon training plan. I did my longest run last weekend of 21 miles & think I have a slightly inflammed tendon inside my ankle. I have to run as I have a charity place. The question I have is should I not run between now & 24th April & keep up my CV fitness using an elliptical machine, leave it a couple of weeks then hope that it gets better & then do a 16-18 run before race day. Any advice would be greatly appreciated.
