In the photo below, the lead pack crosses the first ditch down the opening mile.
If you were a volunteer course marshal, the morning was brisk but just barely damp from the pleasantly unrequited promise of rain for the weekend. As a runner, missing the water at the first two ditches on the opening hill just meant that you were not muddy until the next mile. Most of the experienced runners were in shorts and by the last mile were hoping for rain to cool them off.
