Beau Brummel--thanks, and the way this thread is going, I may have met you already. I've been reading letsrun posts by Ghost of Ashenfelter for years, and I only discovered because of the remark that you responded to that I've known the guy the whole time. Please e-mail if you like--do you run in any of the national masters meets? As for the sub-5's, like Slowpokeman, I never had to think about it back when I came by a mile at that pace in short races, but in the last couple of years I've had to actually train for and race a mile. People like Turnbull and Hinton are so far out of my league that I'll avoid any comparisons--4:56 at age 65?--but I'll try to stay consistent.
