the plan was to run the course starting at the LDS church on McDowell and then running the only significant uphill of the course (from 0.53 miles to 2.06 miles on today's run and from about 4.2 to 5.76 miles on the marathon course) to get a feel for that and to see what my heart rate effort for 9:10 miles would translate to on the down hill portions. I also planned to do one 3 mile section of the course up-tempo but no faster than 8 min mile pace. Well... my watch didn't cooeprate so for much of the run it said my heart rate was in the 170's and 180's. I stopped once to check my heart rate and it wasn't beatring that fast. I stopped again and took it off and tried to wipe of the sensors. no luck... so I ignored the heart rate and ran on effort. The downhill portion after the uphill I ran based upon effort. I started the uptempo segment at 4.5 miles. total time 1:30:07. splits 9:11, 9:33, 8:44, 9:05, 4:26, 8:08, 8:10, 8:05, 9:47, 9:54, 5:03. I finished my hard 3 miles going west on McDowell and immediately turned around so the last 2.5 miles were all uphill. my watch says my average heart rate was 165. right around 6.5 miles all the sudden my watch heart rate dropped to the 140's which was probably accurate.
