The_Man - So let me playback what I'm hearing from you: You set personal bests for total weekly mileage and single run mileage, you've very tired as a result, and you are surprised by this. Do I have that right?
Sand - I've been struggling with the same hydration issue (tho that kind of fluid loss in 90 minutes is staggering). Make sure you hydrate 30 minutes before you run, then have a good 8 oz or so a few minutes before you get started. That should kickstart your rehydration efforts. Figure out how much fluid you can tolerate on the run and find a way to meet those levels - see below for my current strategy in that dept.
Grue - looking forward to more detail around your race.
____________________________________
Moved my 20 miler from Sat to Sun to avoid potential bad weather. Same routine as before, up at 5am and out the door a little after 5:30. This week I filled FOUR 20oz bottles with 1/2 Gatorade & 1/2 water (including ice), setting 3 of them in a cooler w/ice. Also put 3 Gu's and a package of Gu Chomps in there. Every 5 miles I drained a bottle completely and came back for the next bottle & a gel. Because of the ice in the bottles, the first swig or two were actually uncomfortably cold, which I think helped keep my body temp down. Temps were in the upper 60s and humidity was at max 80%. I didn't weigh myself before the run, but I did not lose much weight, despite a couple of times when I really thought I was pouring out the sweat. I targeted 9:15s.
5 miles - 46:15, 9:15s exactly. Ran 1/2 of this in the dark, the other half in complete shade. Felt great.
5 miles - 45:51, 9:11s - Some of this was in the sun, and I could feel the difference in my sweat rate. Shorts were already soaked.
5 miles - 46:07, 9:14s - Took a more shaded route for this part of the run, which helped. Still sweat like crazy when the sun found me. Hammys & quads were hurting pretty good by the end.
3 miles - 27:18,
9:06s - Sped up intentionally to see if I could do it. At this point (18), it was my longest run since the marathon 12/13. My legs were trashed but my breathing was fine.
1 mile - 9:42 - slowed with the idea that I was going to keep running as long as I could before I walked for a minute or two. It hurt.
Final mile - 9:32 - I kept telling myself "Run to that tree. OK run to that cross street," etc. Once I had .35 to go I made myself speed up and finished with everything I had.
TOTAL: 20 miles, 3:04:50, 9:15/mile average.
One of my better long (17+) runs ever. HOWEVER, to keep it in perspective, back in May I was able to do a 16 in 8:17s - that just seems

to me right now. I don't know how I did it. But I have two 15s and two 20s left before Chicago, so I'm hoping with a decrease in temps & humidity I'll be able to rediscover some of that. Regardless I feel like I'm on track.
Oh - and no nap for me, but that's only because I had my first live draft of the season. I think it went well!
