My wakeup HR was 47 again this morning. I ran an easy, comfortable 2 miles. During the first half mile, I ran a pace of about 12:30. By the end o that mile, I was running a pace of about 12 minutes. After another half mile, my pace was at 11:30, and by two miles, my pace was a bit below 11 minutes. I ran the two miles at the same exertion-level, so as my body warmed up I automatically ran faster. Because of this, I'm changing my strategy for Saturday to use the first two miles as a "natural" warmup, as follows:
1/2 mile @ 12:30
1/2 mile @ 12:00
1/2 mile @ 11:30
1/2 mile @ 11:00
Depending how I feel, I'll like to run the last two miles at 10:30 or maybe 10:00.
The forecast for Friday night in Clearfield is a low of 64 (F), so the early morning temperature for the race on Saturday should be in the mid 60s to the mid 70s with sunshine. The early morning sun will be at our backs and shouldn't be a problem.
