The 1978 Western States 100 was the second year the race was held.  Six years earlier, seven soldiers from Fort Riley Kansas proved that the horse trail could be conquered on foot and they were awarded with the “First Finishers on Foot” trophy by Western States founder, Wendell Robie (1895-1984). Two years later, in 1974, Gordy Ainsleigh surprised his horse endurance peers when he ran the 89-mile Western States Trail in less than 24 hours.

Three years later, in 1977, Robie decided it was time to organize a foot race on his trail. The inaugural race was hastily put together by a few volunteers who had horse endurance race experience but did not have much experience with human running races (see episode 71). The first race was mostly self-supported and fairly dangerous in very high temperatures. They were lucky that there were no serious heat-related emergencies, and only three of the 16 starters finished.

Planning for the 1978 Western States 100 Run became more serious and was much better organized. The 1978 race should be considered as the first fully supported Western States Endurance Run which gave all entrants a good chance to finish.
