Thank you both for your advice. I didn't realize until I read your posts, that I was really hoping you would say "Hang in there. Keep logging those miles and your legs will adjust." As many people on this blog have said, running has gone from being a chore that I felt I had to do to lose some weight to something I look forward to everyday. The thought of going "backward" in my mileage is heart-wrenching, even though I know you are most likely right. I really have been feeling good until after my 18 on Saturday which was followed by 2 days of hiking in Tennessee while carrying my 14 month old. I'm not sure I'm ready to give up the idea of running my marathon. It isn't until December and I have two 20 milers and a 22 miler planned between now and then. I think I will take your advice and back off my mileage this week and see how I feel next week. If I don't recover or start to feel overly fatigued after picking the miles back up, then I will reconsider the marathon. I know I'm being stubborn...when I end up injured, feel free to tell me you told me so!
