Feb 27: The knee pain

My nephew is taking part in the Tokyo Marathon on Feb 27th so I'm going to support him. I met him the day before for registration. I walked about 5 hours that day and felt something in my knees but it wasn't painful. Actually I wasn't really walking too much in terms of distance since I've been stopping and checking some exhibitions. Although the following day I can't bend my knees due to the pain. So I forced to bend it (by tolerating the pain) and stretched the muscles then I'm able to walk for a while but ending is the same. I cooled my knees and did some stretch and manage to finish the day, which ended up 7 hours of walking and standing. I suppose the total distance is about 10km.
