I felt great this morning and ran 4 miles on the Jordan River Parkway. My pace varied from 9:30 to 10:50. Most of it was at a 10:30 pace. I ran about 1/4 mile at 9:30 and half a mile at 10. My strategy is to run small bursts of speed above 10:30 and to do rest runs at 10:30. I took walking breaks every half mile and sometimes more often.
The temperature was in the mid 70s, and it felt pretty warm as I ran.
