This is Jeffrey Eggleston, a former elite marathoner (he competed for the US at the 2011, 2013, and 2015 World Championships), and coach of mine, running in the Mile High Mile, which the Boulder Road Runners puts on every August on the University of Colorado track. This year it was in the 90's for all the waves, with quite smoky air (not quite smoky enough to cancel, but close), because of three wildfires burning within 30 miles of Boulder. Everyone was definitely feeling hot hot hot. And Jeffrey was looking it.
