Part of the Happy Trails Running Corner Canyon Trail Series, the Maple Hollow Half Marathon offers runners a September choice through rugged and scenic trails. The 2025 Group Run is scheduled for Saturday, September 13 at 7:00 AM MDT from the Maple Hollow Trailhead, though any registered runner can complete the GPS-mapped course anytime between May 1 and October 31.
Now in its second series year, Maple Hollow is known for being the most technically demanding of the three Corner Canyon half‑marathons, with approximately 2,110 ft of elevation gain over 13.2 miles. The trail winds westward through tunnels, ridges, and creek crossings—crossing county lines from Utah County into Salt Lake County and back, offering commanding views over both valleys.
Happy Trails Running’s GPS format allows flexibility—complete the course when convenient and submit your ridewithGPS activity for timing. Still, many choose the group-run day for community and pacing support. All participants receive a locally made finisher medal and synthetic performance shirt; overall and series leaderboard awards follow in November at a hosted lunch.
