Taking a big chance

Well with 3 weeks to go to the marathon, you typically run your last long run. My IT band hurts when I run on it. If I don't run for a couple days it sort of feels better. With three weeks to go and 3 20+ mile runs behind me I ran another 20 miler today. My leg hurt every step of the way. I took an ibuprofen before I left and two more during the run. They seemed to help some. Had it not been for my knee hurting, I think it would have been my easiest 20 miler ever. I ran it in 3:21 which counts all the stops I made. I think this is the faster I've ever run 20 miles in training. I had recorded a 3:08 on one of my earlier runs but I had not included stops. I hope I didn't completely mess up my knee today. The pain was subdued after the run with a hot bath. I would rate the pain as about a 6 when the run ended. Well I got through it, mentally I know that even if my knee hurts I can make it through MCM.
