Mild start, slight chance of rain

Runners will face temperatures starting at 50°F and rising to 65°F during the race. Light winds from the ESE at 8 mph may provide a slight cooling effect, but they shouldn't impact pacing significantly. With a 40% chance of light rain, it's advisable to prepare for potential wet conditions, and runners should adjust their pace conservatively as temperatures rise.

Race Info

The Deadwood-Mickelson Trail Marathon runs point to point through South Dakota's Black Hills, starting in the small town of Rochford and finishing at the historic Engine House in Deadwood. Most of the course follows the George S. Mickelson Trail, a rail-trail built on a former Chicago, Burlington and Quincy Railroad line that closed to trains in the 1980s and was converted to a trail through the 1990s. The route climbs to roughly 6,200 feet by mile 14 before descending to a finish near 4,500 feet. The course is USATF certified and qualifies for the Boston Marathon. Source
