Ultra-Trail Mogan by UTMB® – MMG
Yucun Square → Jun'Anli
Race guide
Updated 18 July 2026
The MMG is the 48 km distance at Ultra-Trail Mogan by UTMB®, running point to point from Yucun Square to Jun'Anli. Its defining number is the vertical: 2753 m of positive climbing over 48 km, yet a high point of only 667 m. There is no big mountain on this course — instead the gain is assembled from a long series of short, steep climbs and descents, roughly 57 m of ascent for every kilometre. It is a race that stays low but never lets up. With the start at 73 m and the finish at 47 m, MMG is close to net-flat over its full length, so every one of those 2753 climbed metres has to be descended again. That makes it a leg-shredder in disguise: the modest summit lulls runners into underestimating it, while the relentless up-and-down quietly drains the quads. Four intermediate checkpoints and two hard cut-offs break the day into manageable chunks for anyone who respects the profile and starts conservatively.
The course: 48 km of low-altitude, high-volume climbing
MMG travels one way from Yucun Square (0 km, 73 m) to Jun'Anli (48 km, 47 m), through Luoxin Valley (10.1 km, 79 m), Fatou Village (12.9 km, 67 m), the Xiangshuiling Resort Hotel (22.2 km, 256 m) and Biwu (36.6 km, 201 m). The checkpoint elevations all sit low — none above 256 m — which confirms that the 2753 m of total gain is built almost entirely from climbs that rise and fall between the aid stations rather than from any sustained ascent. The 667 m high point is the ceiling the course keeps bumping against without ever settling on top. The opening stretch to Fatou Village stays in the valley (73 m to 67 m via Luoxin at 79 m), so the terrain is gentlest early. It steepens through the middle of the race, with the ground toward Xiangshuiling and beyond carrying the punchiest work. Practically, this is a course you run in constant transitions — hike the steep pitches, run the rolling and descending ground — and the runners who thrive are those comfortable changing gears dozens of times rather than locking into one pace.
Where the race is decided: the climbing middle
The heart of MMG lies between Fatou Village (12.9 km) and Biwu (36.6 km). Fatou sits at just 67 m, Xiangshuiling at 256 m and Biwu at 201 m, but the cumulative climbing across this middle third is where the bulk of the 2753 m D+ accrues, including the passages up toward the 667 m high point. This is the section that separates a strong finish from a survival march: the low checkpoint elevations hide how much vertical is being banked on the climbs between them. The closing 11.4 km from Biwu (201 m) descends net to the Jun'Anli finish at 47 m, so a runner who has protected their legs through the climbing middle can finish fast on tired-but-functional quads. Conversely, anyone who attacked the early rollers will find the descents to the line punishing. The winning tactic is to keep the steep climbs efficient and unhurried through the middle, then let the final descent to Jun'Anli reward the restraint.
Pacing and fuelling around the cut-offs
MMG runs on Saturday and enforces three deadlines: Fatou Village closes at 10:00, Biwu at 17:00, and the Jun'Anli finish at 20:00. The tightest of these to watch is the long haul to Biwu — 23.7 km of the day's steepest climbing between the Fatou and Biwu checkpoints — so build a time cushion early rather than assuming the back half will come easy. Once through Biwu with time in hand, the descending 11.4 km to the finish is the most forgiving part of the day. For fuelling, the checkpoints are reasonably spaced (Luoxin/Fatou early, then Xiangshuiling at 22.2 km and Biwu at 36.6 km), but the gaps still ask for self-sufficiency of 9 to 14 km at a stretch. Carry fluids and calories to bridge those legs, and top up properly at Xiangshuiling and Biwu, the two checkpoints that bracket the hardest climbing. Because the constant ascending burns more than the low summit implies, start eating early and keep a steady intake rather than waiting until you feel depleted.
Conditions to expect
This is a low-elevation course from end to end — nothing on it climbs above 667 m — so altitude plays no part and there is no high-mountain exposure to prepare for. The demand is muscular: 2753 m of climbing and an equal amount of descending over 48 km will test quads and ankles far more than lungs. The Saturday cut-off spread from 10:00 to 20:00 means the field can expect to race largely in daylight, with slower runners potentially finishing toward evening. Because MMG gives back every metre it climbs, descending durability is the trait to build in training. Long sessions of repeated short climbs and descents will prepare the legs far better than steady-state mountain climbs, and confident downhill footwork will save meaningful time on the many drops, especially the run-in from Biwu. Match your kit and fuelling to the four-checkpoint structure, respect the vertical the profile hides, and MMG becomes a rewarding, honest 48 km rather than an ambush.
