DuPont Trail Marathon Association

The DuPont Trail Marathon Association was the dream in 2015 of John “Crazy Man” Schaphorst, to organize a race in Dupont, WA. The DTMA started with a February Marathon, Half-Marathon and 5K. Now we are expanding to a September event, known as Crazy Man Races. And starting in 2018 we have the Dupont Endurance Challenge 3 day race with 2 day and 24 hour races.



To bring people together both new to trail running and veterans to engage in the joy, thrill and camaraderie of the sport. We intend to put on an annual marathon in DuPont, WA*, but also around the area.

*All extra proceeds from our annual DuPont Trail Marathon will be given to the City of DuPont for trail maintenance.  



Rich W. after our inaugural race (3/5/2016) posted an awesome summary of our first race. He was a participant.
