Predictive climatology for the Olympic Marathon and race walking events in Barcelona 1992

Abstract

During 1990 in New York and again in Barcelona in the following year, the International Marathon Medical Directors Association (IMMDA) initiated studies to monitor climatological conditions accompanying several endurance outdoor sports events in different locations. The aim was to identify the changing thermal stress on both a competitor and exposed spectator along the course of any major endurance racing event around the world where there were climatological conditions similar to Barcelona during the 1992 Olympic Games. In this way any combination of type of surroundings, time of day climatological conditions, etc., along an event's course found to present a thermal stress to either an athlete or spectator might be avoided by better scheduling, better routing, increasing the number of aid stations along a route, and other precautions. To evaluate a single measure of the climatological conditions surrounding an event, a monitor with three thermometers was used to obtain the wet bulb global temperature val...
