Sundance to Spearfish Marathon
The Sundance to Spearfish Marathon is a marathon event scheduled for Sunday, September 13, 2026. Registration for the event is capped at 250 participants, which keeps the field limited in size.
In the previous year the event ranked as the 402nd largest marathon in the United States. Last year 25.9% of finishers qualified for the Boston Marathon, a percentage that placed the event 23rd highest for Boston qualifiers among U.S. marathons.
The event is organized in partnership with Jazz Hands Running. That partnership makes this marathon available alongside other marathons and triathlons in the area under a shared registration and event management arrangement. Visit the organization's website for the most recent information.
