Day 5 of the inaugural Mainly Marathons Prairie Series was run around the Lake at Crystal Cove Park in South Sioux City, NE. The course consisted of a concrete path that went three-fourths of the way around the lake to a turnaround and then back the same way to the start/finish. We had to do 12 out and backs for the full marathon. There was shade on about 50% of the course in the morning, but it became diminished as it got closer to noon. The hottest part of the course was in the final stretch just before the turnaround. I took advantage of the 4:30 a.m. early start and I am very glad I did, as the heat index was 101 degrees at the start. It then cooled off before climbing to a heat index of about 108. Plenty of ice water with towels was was available at the two aid stations, which were just a little more than a mile apart.
