I could not go for Mumbai Marathon today because I had some knee pain since my 32 km 11 December 2011 run. I realized only two days ago that it was because my worn out shoes was aiding the mild underpronation that I have. I wish I had diagnosed my case earlier; I have been running long distance of up to 18 kms in a day after December 11 but was not sure of doing a full marathon. I had cancelled my Mumbai tickets some days ago.
But I was running so effortlessly and smoothly that I had forgotten about it. This is a lesson for me: Keep checking the shoes, gait and all that matters. See photos and be careful if you are a runner. Running is no easy sports: injuries are common if you are not careful. I am buying new Asics shoes very soon (online shopping probably from Myntra).
