Malaysia Ultra-Trail by UTMB – MY50
Jalan Kota, Taiping
Race guide
Updated 18 July 2026
The MY50 is the 55 km middle distance at Malaysia Ultra-Trail by UTMB, starting and finishing on Jalan Kota in Taiping, Perak. It carries 1627 m of climbing, but like its sister races the vertical does not come from altitude: the course high point is only 318 m and most of the route runs at valley-floor level between 18 m and 33 m. This is a long, low, rolling jungle loop where the difficulty is measured in heat, humidity and accumulated small climbs rather than in mountains. With a wide finish window and long flat linking sections, the MY50 can be a fast day for a well-prepared runner. But the same low-lying, tropical terrain that keeps the gradients gentle for most of the loop also concentrates the real climbing into a short late stretch, so how you manage the flat middle largely determines how the sharp finish feels.
The Course and Terrain
From the Jalan Kota start at 20 m, the MY50 runs out to Tiger Temple at 9.6 km (33 m), then on to the Spritzer Ecopark crew point at 17.4 km (18 m). These opening segments hug the valley floor and give runners a long stretch of runnable, low trail. The route continues through the KTM Tunnel at 23.1 km (23 m) — a former railway tunnel that is a genuine landmark on the course — before reaching Changkat Ibol at 35.5 km (27 m). Beyond Changkat Ibol the loop threads through a U-Turn at Kuning Sari (39.7 km, 28 m) and then finally tips upward to Peak 300 at 42.2 km (180 m), the highest checkpoint on the route, before descending back to the finish at 54.4 km and 20 m. The takeaway from those numbers is stark: for the first 40 km you are barely above sea level, and the 1627 m of total gain is delivered as a long series of small undulations plus the concentrated climbing around Peak 300 near the end. Expect humid rainforest trail, the novelty of the tunnel passage, and a course that stays deceptively low until it doesn't.
Where the Race Is Decided
The MY50 is won and lost in its final third. For 40 kilometres the terrain lets you run, and it is tempting to treat that as free speed. But the climb to Peak 300 at 42.2 km arrives when your legs are already 40 km deep and the tropical heat has been working on you for hours. Runners who spent the flat middle chasing splits tend to arrive here depleted, and the sharp rise to 180 m feels far tougher than its height suggests. The closing 12 km from Peak 300 back to the finish is the other decisive block. It is the longest stretch without a manned checkpoint after Changkat Ibol, so the late climb and the run home have to be covered on your own supplies and whatever composure you have left. The riders who manage the flat sections at a controlled, sustainable effort and keep fuelling steadily are the ones who can still run that final descent, rather than walking it in the heat.
How to Pace and Fuel It
Two cut-offs frame the day. Changkat Ibol at 35.5 km closes at Sat 15:00, and the finish closes at Sat 22:00. That leaves a broad overall window, so the strategy is not to race the early cut-off but to arrive at Changkat Ibol with enough in the tank for the Peak 300 climb and the long run-in. Use the Spritzer Ecopark crew point at 17.4 km and the Changkat Ibol crew point at 35.5 km as your two main resupply and reset stops — both are crew points, so plan support, dry kit and calories around them. Aid spacing is manageable for most of the loop: roughly 9.6 km to Tiger Temple, then similar gaps through Spritzer Ecopark, the KTM Tunnel and Changkat Ibol. The section to plan hardest for is the run from Changkat Ibol over Peak 300 to the finish, close to 19 km with only the brief Kuning Sari turn in between. Leave Changkat Ibol carrying full fluids and enough fuel for that block, because bonking on Peak 300 late in a hot day is the classic MY50 failure. Drink and take electrolytes proactively from the start rather than trying to catch up once you are already behind.
The Conditions to Expect
With every checkpoint between 18 m and 180 m and a high point of just 318 m, the MY50 is an equatorial low-altitude race, and heat and humidity are the dominant challenge. The long flat sections that look like easy speed on the map offer little shade relief from the tropical air, and the closing climb to Peak 300 will spike your core temperature at exactly the moment you can least afford it. Cooling strategies — dousing at aid stations, loosened breathable kit, steady fluid intake — matter as much here as any climbing legs. Underfoot, expect a mix of runnable jungle trail, the distinctive KTM Tunnel passage, and steeper, greasier pitches on the Peak 300 section. Well-lugged shoes and a reliable headlamp are worth prioritising, since a slower runner working toward the Sat 22:00 finish cut-off will be out well into the evening. Pace the flats with discipline, fuel and hydrate from the gun, and save your effort for the late climb, and the MY50 rewards you with a strong, running finish back into Taiping.
