US Road Running - Stillwater

The US Road Running event in Stillwater takes place at Boomer Lake Park. The race headquarters is located at Shelter #3, situated on the west side of the lake next to the Boomer Park Splash Pad. Participants are advised to navigate specifically to the west side, as general park addresses often lead to the east side of the water.

This event features multiple distance options on out-and-back paved courses. The 5K and 10K routes utilize a 1.56-mile out-and-back segment. Runners in the 5K complete this loop once, while 10K participants complete it twice. The Half Marathon follows a slightly different 1.64-mile out-and-back segment, requiring runners to complete the loop four times to reach the total distance of 13.1 miles. All race distances are subject to a overall course time limit of 6 hours.

Available race categories include:

  • 5K
  • 10K
  • Half Marathon (13.1 miles)

Registration is managed online, and there is no option for on-site registration on the day of the event. Packet pickup is conducted at the race location shortly before the start. Every finisher receives a medal, and participants have the option to compete for a best costume award. This event is part of the US Road Running Race Series, allowing participants to earn series points. Visit the organization's website for the most recent information.
