OK, I just checked out last year's results for the HH (Historic Half marathon): the last person to cross the finish line came in at 3:58:14. That's around 18.17 minutes per mile. I can definitely do that pace by walking, and probably faster. So at the very least I (hopefully) won't come in dead last, even if I have to walk most of it. The last person in the Marine Corps Marathon last year came in at 7:16:57. That's 16.68 minutes per mile. I could probably walk that right now too.
This is very encouraging... except that the records DON'T show if these people were injured or handicapped or otherwise unfit. I can only hope that they were just slow.
