Comfortable temps, warming through the race, chance of rain
Mild 55°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 65°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready.

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
