During my last long (20 mile) run last Sunday, my left knee started to hurt. I got to around mile 17 and it brought me to a walking pace and was too painful to run.
Although I didn't want to make things worse, I did still want to complete the distance. I managed the final few miles with a combination of walking and running (the pain would sometimes allow me to run again for a few minutes, before bringing me to a walking pace again).
I tried to rest my knee after and missed my scheduled Tuesday 7-miler as a result. I went out this morning (Thursday) but only managed 3 miles - my knee definately felt tender still and felt likely to bring me to a walking pace again if I pushed it much harder.
I'm now really concerned about how to ensure I'm fit for London on the 21st. What advice would you give in terms of treatment and training distances during the next couple of weeks please?
