On August 27, in the remote Pembina Gorge region of North Dakota, Ground Up Adventures will host END-AR 24, an all-day, all-night 24-hour adventure race with mountain biking, orienteering, trail running, and pack-rafting on rivers and lakes. North Dakota? Yes, not your typical state for high adventure. But Ground Up Adventures is run by Andy Magness, a local hardman with several expedition-length adventure races under his belt who is a member of Team GearJunkie/YogaSlackers.

END-AR 24 is a part of the nationwide Checkpoint Tracker race series. It marks the end of a season of adventure events put together by Ground Up in North Dakota. Check it out here and sign up to race at the end of this month!
