About the Sundance-to-Spearfish Marathon
Few qualifiers cross a state line from start to finish. This small race begins in Sundance, Wyoming and runs to Spearfish, South Dakota, with the finish city serving as the event base.
Course
The certified point-to-point route trends downhill toward Spearfish. The loss of elevation supports fast times, but sustained descending can punish the quadriceps when early miles are run too aggressively.
Race-day weather
September near the northern Black Hills can start cold and become warm, with wind or a passing shower possible. Different conditions at the start and finish are worth planning for.
