Southern Utah Triathlon

What the Southern Utah Triathlon Is

The Southern Utah Triathlon runs every October at Quail Creek State Park, a reservoir north of St. George near Hurricane. On Hill Events organizes two standard distances on the same morning: a sprint (750-meter swim, 12.4-mile bike, 3.1-mile run) and an Olympic distance run as what the race calls an "F1 format" — the sprint course simply repeated, doubling every leg to a 1,500-meter swim, 24.8-mile bike, and 6.2-mile run. Sprint and Olympic relay teams round out the field alongside individual racers.

The Course at Quail Creek

The swim is a triangular buoy course with roughly 250 meters between markers — one lap for sprint athletes, two for Olympic. The bike is an out-and-back along the frontage road toward Leeds, flat off the start but with a real climb around mile three; Olympic racers take that climb twice, which is what turns "scenic" into genuinely hard rather than a flat time trial. The run follows the shoreline and passes the dam before turning back, paved the entire way. Quail Creek itself is a 600-acre reservoir fed mostly by piped-in Virgin River water rather than by its namesake creek, and it holds some of the warmest water in the state — worth knowing if you've also read about the cooler swim spots around St. George.

Getting There and Parking

Race-day parking at Quail Creek runs through a prepaid pass sold on the state park's own event page rather than at the gate, separate from the park's regular day-use lots. Packet pickup happens the afternoon before at the St. George Running Center; there's a same-day option at the transition area the next morning for anyone who can't make the Friday window. For the park beyond race day — camping, the boat ramp, the petroglyphs along the shoreline — see the Quail Creek State Park guide.

How to Spectate

Because the Olympic distance is the sprint loop run twice, the transition area sees every Olympic athlete pass through it twice instead of once, so spectators who post up near transition or the turnarounds get more looks at the field than a single-loop race would give them. An awards ceremony follows at the transition area once the course sweep clears.

Southern Utah Triathlon vs. Ironman 70.3 St. George

Washington County hosts two very different triathlons a few miles apart. Ironman 70.3 St. George swims at Sand Hollow and finishes with a half-iron-distance day that closes out downtown; the Southern Utah Triathlon swims at Quail Creek, tops out at Olympic distance, and finishes back where it started. It's a smaller field on a shorter day, built around one lake and an out-and-back road instead of a point-to-point route through the city — closer to a well-run local race than a stop on a global circuit.

Who the Race Suits

The sprint distance is a reasonable first triathlon: a short paved bike leg, a run that stays on paved road the whole way, and water warm enough that the wetsuit question is rarely a hard one. Quail Creek has also carried serious racing before — the reservoir hosted the 2021 Americas Triathlon Championships, an elite international event run by USA Triathlon, though that race and the Southern Utah Triathlon are separate events with separate organizers. Athletes chasing a flat, fast Olympic split may want a different course; the mile-three climb, doubled at Olympic distance, is the trade-off for the views. First-timers and families who'd rather watch from shore than in the water have plenty to fill the rest of race weekend, from Kanarraville Falls to Hurricane's own heritage park and museum in the La Verkin corridor.
