⏵ Course guide · 2,600 ft down, with one climb in the way
St. George descends about 2,600 feet from the Pine Valley Mountains into St. George through red-rock desert, a fast, BQ-friendly course that is not a straight downhill: the Veyo hill interrupts the descent between miles 7 and 11. I will walk you through the course and registration first, then give you a pacing plan built for the downhill-then-Veyo-then-downhill profile, plus free tools to dial in your own numbers.
These facts come from brooksee.com/stg and sgcityutah.gov. Confirm the current-year registration window and checkpoint cutoffs on those sites before you commit, since this race typically fills before race week.
The course drops from about 5,240 feet in the Pine Valley Mountains to about 2,680 feet in St. George, a net descent of roughly 2,600 feet through scenic red-rock desert terrain.
After a fast opening descent from the high mountain start, a genuine climb around the town of Veyo interrupts the downhill profile between miles 7 and 11. This is where an overpaced opening gets exposed, and where runners who treated the first miles as pure free downhill speed start to pay for it.
Past Veyo, the course resumes its long downhill run into St. George. The net drop is real and helps most runners produce a faster time than they would on flat ground, but pockets of steep grade throughout the descent can trash unprepared quads, especially late in the race when fatigue is already accumulating.
Starting near 5,240 feet keeps the air cool at the gun, often cold enough for bonfires at the start line while runners wait in the pre-dawn dark. By the time you finish in St. George, the day has typically warmed considerably, so the temperature swing over 26.2 miles is part of the course, not an anomaly.
The mile 23.1 checkpoint (1:15 p.m.) and the 2:15 p.m. finish close are real deadlines, so build your pacing plan around honest effort, not around banking early downhill time.
The early descent from the mountain start will pull your pace faster than your fitness alone would produce. That is fine in moderation, but do not let it turn into an effort level you cannot sustain once Veyo arrives around mile 7.
A grade-adjusted pace target for the Veyo climb and for the steeper sections of the later descent gives you a far more honest number than a single flat-course pace applied across a route that changes character three separate times.

⏵ Train for it with Summit Line
Get a race-day plan built around YOUR fitness, this downhill-Veyo-downhill course profile, and your projected splits. Summit Line reads your real training, builds a plan for quad-durable downhill running and a real climb mid-race, and rehearses your fueling so race day is something you execute, not guess at.
Yes, with a net drop of about 2,600 feet from the Pine Valley Mountains start (roughly 5,240 ft) to the finish in St. George (roughly 2,680 ft), which makes it one of the more popular fast, BQ-friendly courses in the West. But it is not a straight descent: a notable climb around Veyo interrupts the drop between miles 7 and 11, and the grades in places are steep enough to punish anyone who tries to bank time early. The high-elevation start also means cool, thin air at the gun that warms considerably by the finish.
The Veyo hill is the notable climb that interrupts St. George's overall downhill profile, arriving between miles 7 and 11. After a fast opening descent from the high mountain start, this stretch asks for real climbing legs before the course resumes its long downhill run into the city. Runners who treat the opening miles as pure free speed often find the Veyo hill a rude surprise, so plan for it rather than being caught off guard.
Resist the temptation to let the early downhill from the high mountain start dictate a pace faster than your fitness supports; the Veyo hill around miles 7-11 will expose an overpaced start, and the steep grades on the descent, both before and after Veyo, punish quads that have already been trashed by too much early speed. Run the opening downhill by effort, treat Veyo as a real climb, and save something for the long downhill run into St. George where the course keeps dropping toward the finish.
The overall time limit is about 6 hours 15 minutes. The key intermediate checkpoint is mile 23.1, which you must reach by 1:15 p.m., and the finish line itself closes at 2:15 p.m. Build your pacing plan around that mile 23.1 checkpoint specifically, since it is the checkpoint that determines whether you get an official finish.
Registration has been first-come, first-served since 2017, when the race discontinued its lottery. Registration opens early in the calendar year and typically fills by around August 31, so this is a race you need to register for well before race week, not a race you can decide to run on short notice.
Starting with the 2027 Boston qualifying cycle, the BAA adds a time penalty to marathons run on courses with large net downhill, a rule aimed squarely at courses like Revel Big Bear. St. George's net drop of about 2,600 feet is real but meaningfully smaller than the steepest Revel-style courses, so the fact sheet behind this guide places it in a lesser penalty tier rather than the same bucket as Revel Big Bear. The exact minute adjustment and bucket boundary for St. George specifically are not something we can confirm here, so check the current BAA course-index rules directly before you count on a St. George finish time for a Boston qualifying attempt.
Expect a big temperature swing over the course of the race. The high-elevation mountain start runs cold, commonly in the 30s to 40s Fahrenheit before dawn, with bonfires at the start area while runners wait. By the time you reach St. George in the later miles, temperatures often climb into the 60s to 70s-plus Fahrenheit. Dress in removable layers for the cold start and be ready for meaningfully warmer conditions by the finish.
