Big-wave surfer Laird Hamilton announced on Monday that he will launch his own obstacle course race series next year. Called Force of Nature, the series is composed of six events, each featuring 20 obstacles and a length of between eight and 10 miles. The series debuts in Southern California on April 26, then heads to Philadelphia, Detroit, Chicago, the Tri-State area (Englishtown, New Jersey), and Northern California.
Advertised obstacles feature extreme temperatures, including a crawl through snow and a dome called the Furnace that’s heated to over 130 degrees. At the end of the course, racers must dive to the bottom of a black tank filled with ice water to retrieve their finisher medals.
Hamilton is putting on the series in conjunction with Southern California–based production company MESP, Inc., which puts on the Down & Dirty Obstacle Race series and the star-studded Nautica Malibu Triathlon.
