St. George, United States of America · Sunday 4 October 2026
This race is ideal for trail runners seeking a relatively gentle introduction to longer distances or those wanting to log miles without excessive climbing. The flat to gently rolling terrain means you won't face grinding uphills or technical descents that demand constant technical footwork, making it suitable for runners who prefer forward momentum over elevation strategy. If you're training for a road marathon but want trail experience, or you simply enjoy dirt under your feet without punishing your legs, this fits the bill. The high elevation starting point around 830 meters does mean you'll be running at altitude for the entire race, which can surprise runners unaccustomed to thinner air even on modest grades. The main challenge you'll face is the desert environment itself. St. George sits in southwestern Utah's red rock country, and trail marathons here mean exposure to sun, heat, and sparse shade for most of the race. Even in October, southern Utah can warm up significantly mid-day, so pacing conservatively early and managing your fluid intake becomes critical. The trail surface also tends to be rocky and uneven underfoot, which isn't technical in the climbing sense but demands steady concentration to avoid ankle rolls, especially as fatigue sets in over 42 kilometers. If you're accustomed to running smooth fire roads or groomed paths, expect to work harder on foot placement than the elevation profile alone suggests.
