In the late ''70s and early '80s, when running road races in South Florida, I used to take a half gallon jug of cold water to the start and pour it over my head just before the gun. As a high school coach I had my kids "water down" in a similar fashion just before the start of brutally hot Cross Country races. We did well - five State wins from '82-'97 and top five my last 12 years of coaching - but no one ever emulated us. Fine with me but it really surprised me. I even mentioned it at state XC coaches clinics but no one picked up on it. Bizarre. It was a no-brainer, I thought. Be as cool as possible for as long as possible.
Needless to say, I am sure lots of others discovered on their own, as I did, the benefit of cooling down before races - and training. In fact I recall an old "Playboy" article about '68 Olympic marathoner Ron Daws. On a hot day at Boston he knocked on a door of a house near the start. No one home. So he opened the unlocked door, went upstairs to the bathroom. Ran a cold tub. Immersed himself. Got out, drsined the tub, dripped down the stairs and went over to the start. Common sense! Well, except maybe for the breaking and entering.
