Rockin' Rockwoods 53K and 1/2 Marathon
Rockin' Rockwoods is an annual trail race held on September 26, 2026, at Greensfelder County Park, 4515 Hencken Road, Wildwood, MO. The event includes multiple simultaneous trail distances on the Green Rock Trail and is presented by Terrain Trail Runners.
The course surface varies from hard pack dirt to loose, uneven rock and features roots, creek crossings, and steep, technical terrain. About 95% of the route is single track. The 53K course combines two out-and-back sections with an approximate elevation gain of 5,200 ft. The 1/2 Marathon and 1/2 Marathon RUCK are out-and-back courses with an approximate elevation gain of 2,200 ft.
Aid support includes four manned stations stocked with water, electrolyte drinks, gels, snacks, and first aid. Aid stations are spaced at roughly 5.5 miles apart with no gap larger than about 7.5 miles. Restrooms are available at the start/finish and at the turnaround aid station.
Registration details note a guaranteed swag deadline of August 23, 2026; alternative swag may be provided for later entries. Included items and post-race services for entrants mention a custom hoodie, custom finisher medals or rucking patch, and post-race food with one beverage per runner. The event operates as cup-free and requests participants bring their own drinking receptacle and mess kit. The race began a partnership with the Trail Mix Fund in December 2025 to cover registration fees for runners who cannot afford them. Visit the organization's website for the most recent information.
