Chord Energy Williston Marathon

Lace up for an unforgettable journey at the Chord Energy Williston Marathon, set to take place on June 6, 2026, in Williston, ND. This premier event offers a truly unique experience: the chance to run on the runway of the Williston Basin International Airport! Choose your challenge from a full Marathon (26.2M), Half Marathon (13.1M), 10K (6.2M), or 5K (3.1M), with the Marathon distance also serving as a Boston Qualifier.

The course itself is described as a rolling, double-loop path around the XWA Airport, providing an engaging terrain for runners. All races commence and conclude at the Overland Aviation building on the airport campus, offering ample parking and designated spots for spectators to cheer on participants. Runners can expect well-supported routes with six water stations along the marathon and half marathon courses, stocked with basic first aid, electrolytes, and light refuel options. Restrooms are conveniently located at both the start line and along the route. Typical race day conditions in early June include comfortable highs around 75F and lows around 49F, with a minimal 12% chance of precipitation.

Beyond the unique setting, the Chord Energy Williston Marathon is a non-profit event, with all proceeds directly benefiting the Upper Missouri Relay For Life. Funds raised support patient care and travel expenses for cancer patients in the Williston, ND, area, adding a meaningful cause to your race day efforts. While extensive runner reviews are not yet widely available, the event's growing reputation as the 4th Annual gathering and its Boston Qualifier status hint at its potential to become a cherished fixture on the running calendar.
