Which, what I've been doing in the hills has been around 10:45 for the most part, give or take :15 on either side.
According to the Galloway Calculator (colby is an information junkie):
Mile: 7:06 (used my 5k time and backed it out)
5k: 7:39 min/mile (23:43)
10k: 8:10 min/mile (50:37)
Half: 8:31 min/mile (1:51:37)
Marathon: 9:14 min/mile (4:01:50)
Marathon Training: 11:14 min/mile (4:54:14)

DEFINITELY more conservative (realistic?) than the Runner's World calculator. But, hey... if this one says I can run 4:01:50 and the other 3:49, maybe I can split the difference and at least reach 4:00

My long runs have been at 9:45 to 10:30 pace (based on watching mile markers and checking my watch). Latest was 18 miles in 3:05, 10:16 pace. I guess I won't feel bad if they start slowing down.

I'm considering a) finding the 4:00 pacer at my marathon and just going for it, and b) getting a Garmin (or something) that can track distance/pace for me so I can practice my race pace (9:09 for a 4 hour) and drill it into my head for the next 4 weeks.

On topic: Today I ran more than 4 but probably not 5 miles (did not measure) easy, in 45 minutes or so. I ran a different route so I don't know the distance, was trying to go by time and not get caught up in the speed. Yesterday I went 5 miles in 38:45, I was not able to go all 8 on the menu due to time constraints. I think it was probably better that way, in my long run I got a blister forming on my forefoot underneath-ish my big toe, and I need it to heal by this weekend's 20-miler.

I read someone's recent 100-miler race report. It kind of reminds me of Forrest Gump running and running and running and running. "And when I got there, I figured, since I'd gone this far, I might as well turn around, just keep on going." Or, "Why are you doing this?" "I just felt like running." It's ambitious and challenging and a little scary (okay, crazy), but good luck!!
