Silverstreams (near Underberg) → Premier Resort Sani Pass
Race guide
Updated 19 July 2026
The RMB Ultra-Trail Drakensberg UTD100 is a 103.9 km point-to-point ultra that traverses one of South Africa's most dramatic mountain landscapes, running from Silverstreams near Underberg to the Premier Resort Sani Pass. With 2753 m of total ascent and a high point of 2474 m, the route weaves through the foothills and escarpment edges of the Drakensberg, demanding technical trail running ability, sound altitude awareness and strong self-sufficiency across long stretches between checkpoints. The race starts at Silverstreams (1755 m) and finishes at Premier Resort Sani Pass (1539 m), making it a net descent on paper — but that figure is deceptive. The course rolls relentlessly through river valleys, open grasslands and rocky mountain trails, with two manned checkpoints at Sani Valley Gate (58.3 km) and Crystal Waters (97.4 km) bookending the business end of the race. The overall cut-off is 07:00 on Day+1, giving runners a generous but firm window to manage whatever the Drakensberg throws at them.
Course & Terrain
The route runs broadly south-to-north through the Southern Drakensberg, linking farm tracks, jeep roads, single-track footpaths and open mountain terrain. From the start at Silverstreams (1755 m), the course climbs and rolls through classic Drakensberg grassland and valley systems before reaching the Sani Valley Gate checkpoint at 58.3 km (1781 m) — a long first leg of over 58 km with no confirmed intermediate crew access, meaning runners must be self-sufficient in nutrition and minor kit management for the majority of the night and early morning hours. Beyond Sani Valley Gate the terrain becomes more sustained and technically demanding as you approach the high point of 2474 m. The final third of the race passes through Crystal Waters (97.4 km, 1807 m), a crew-accessible point that arrives almost too late to rescue an under-fuelled runner. The finish at Premier Resort Sani Pass sits at 1539 m, requiring a descent off the high terrain in the closing kilometres. Trail surfaces vary from soft, boggy grassland after rain to firm rocky paths on the exposed ridges, and river crossings are likely depending on conditions.
Decisive Climbs & Descents
The race's defining challenge is its high point at 2474 m, reached somewhere in the middle section of the course between Sani Valley Gate and Crystal Waters. This is where the race is won or lost: runners who have burned too many matches on the long opening 58 km to Sani Valley Gate will find the climb to the high point — nearly 700 m above the surrounding valley floor — extremely hard to manage on tired legs. The altitude at these elevations in the Drakensberg is not extreme by global standards but is sufficient to slow breathing and increase perceived effort, particularly at night or in cold, windy conditions. The descent from the high terrain into Crystal Waters (97.4 km) and then on to the Sani Pass finish (1539 m) offers an opportunity to recoup time, but the legs at this stage of a 100 km effort are rarely cooperative. Rocky, uneven descent trails in the Drakensberg demand concentration and intact quads. Runners who have managed their downhill effort through the first two-thirds of the course will have a significant advantage in these closing kilometres.
Pacing & Fuelling Strategy
With Sani Valley Gate not appearing until 58.3 km, the opening leg is the longest unsupported stretch of the race and the one that most frequently derails runners. The temptation to push on the earlier, flatter sections must be resisted: arriving at the 58 km checkpoint already depleted sets up a miserable second half. A conservative, even-effort approach through the first 50 km — prioritising eating and drinking on schedule rather than chasing pace — is the most reliable route to the finish. Crew access only opens at Crystal Waters (97.4 km) and the finish, so drop bags or careful pack loading must cover all nutrition and hydration needs for the vast majority of the course. Plan for at minimum two full nutrition cycles between start and Sani Valley Gate, and another full cycle from Sani Valley Gate to Crystal Waters. The high point at 2474 m often coincides with the coldest and darkest part of the effort for most mid-pack runners; carrying a hot drink thermos or planning for warm food at Sani Valley Gate can make a material difference to morale and performance heading into the technical high-country section.
Conditions to Expect
The Southern Drakensberg is notoriously changeable. Temperatures at the start (1755 m) may be mild, but at the high point of 2474 m conditions can deteriorate rapidly into cold wind, mist, rain or even snow, particularly if the race falls in shoulder-season months. Afternoon and evening thunderstorms are a frequent feature of the Drakensberg summer landscape, and the exposed ridgelines and open grasslands above 2000 m offer no shelter. Waterproof and wind-resistant layers are essential kit, not optional. Night running will be a reality for almost every competitor: with a cut-off of 07:00 on Day+1, runners will spend hours in darkness on the mountain. Reliable headtorch systems with spare batteries or a backup light are non-negotiable. River and stream crossings may become more serious after heavy rain, and boggy grassland sections will slow pace significantly underfoot. The combination of altitude, cold, technical terrain and distance makes this a race where conservative kit and weather preparation consistently outperforms minimal-pack gambles.
