Each Race is different. And each race has multiple waves. The 42K race begins at 6:45, the 21k race has two waves that begin at 6:20 or 6:30, the 10k race has four waves beginning at 9:10, 9:30, 9:45, and 10:00, while the 5k race has two waves that begin at 7:15 and 7:30. All the runners on Team Lema'an Achai will be in the same wave as anyone else running that race so they will be able to run together and get to the starting line as a group.
Runners should arrive at the starting line 15 minutes before the indicated time.
