John Estle has had a long affiliation with the Equinox Marathon, serving as its race director for a number of years and, through his SportAlaska company, has performed timing services for the race for as long as anyone can remember. He is an uber-numbers guy–just the sort of person you want timing your races–and for a number of years prepared detailed notes about each race. The following documents provide both a historical perspective of the Equinox as well as some insights into the way to success in the race.
