I finally ran out of gas. I knew it was bound to happen and today was that day. I started the run feeling pretty good. 7 miles into the run I had thoughts of maybe making 40 miles today. I thought how awesome it would be to hit all my goal distances in the same weekend (6000 meter swim, 150-175 miles bike, and 40 mile run)... Well, I ran into some friends for miles 7-12 and ended up running harder than I intended. That stretch took more out of me than I thought as once I reached mile 18 things got rough. I was OK mentally, but the energy was low. Looking back on the run I KNOW I was dehydrated. I did weigh myself before starting the run and was 5 lbs light before even starting. I lost another 5 lbs during the run.
On the upside, I did make 20 miles and my knee felt better today than in the past. I might just need to suck it up and try to do a run/walk on the treadmill to get to the magic 40 mile mark. The Florida weather just is not conducive to that distance right now.
