Oman by UTMB – Jabal Classic (100K)
Al Hamra → Birkat Al Mouz
Race guide
Updated 29 June 2026
The Jabal Classic is the headline 100K event of Oman by UTMB, covering 103 km from Al Hamra to Birkat Al Mouz with 4,621 m of climbing and a high point of 2,267 m. It is a point-to-point journey through one of the most dramatic mountain landscapes in the Arabian Peninsula, threading through ancient villages, deep wadis and exposed ridgelines before dropping to the finish at Birkat Al Mouz. With a single cut-off posted at the finish — Day 13:00 — the race demands self-sufficiency, smart pacing and an honest respect for desert-mountain conditions. This is not a course that rewards aggression early; it is a course that rewards runners who are still moving purposefully when others are struggling to stay cool and on their feet.
Course & Terrain
Starting at Al Hamra at 684 m elevation, the Jabal Classic climbs steadily into Oman's Hajar Mountains, reaching its high point of 2,267 m before the long descent to Birkat Al Mouz at 598 m. The 103 km route crosses a full spectrum of terrain: compacted gravel tracks through ancient falaj-irrigated villages, loose rocky trails on steep mountain flanks, exposed ridgeline traverses and technical descents on scree and broken stone. The early sections out of Al Hamra can feel deceptively approachable — the gradient is manageable and the surroundings are captivating — but the cumulative 4,621 m of ascent means nothing is truly free here. Footing demands constant attention on both the uphills and the long descents; ankle support and durable outsoles are not optional on this terrain.
The Decisive Climbs and Descents
The major ascent to the 2,267 m high point is the physical and psychological centrepiece of the race. It is a sustained, grinding effort that will expose any runner who has gone out too hard in the opening kilometres. The descent from the high point toward Birkat Al Mouz is where many races unravel: tired legs on steep, loose terrain will punish poor quad management from earlier in the day. Treat every downhill in the first half as a future investment — run them within yourself, keep your stride short and controlled, and arrive at the technical sections of the descent with something left. The finish at Birkat Al Mouz is lower than the start, but the road to get there is rarely straightforward, and the final kilometres after a long descent often feel longer than the numbers suggest.
Pacing Strategy
The single most important decision in the Jabal Classic is how you manage the first third of the race. The valleys and lower trails out of Al Hamra can feel like an invitation to push — resist it completely. A patient, almost social early pace is not a sacrifice; it is the deposit that funds a strong second half. The real race begins on the far side of the high point, when fatigue, heat and accumulated climbing begin to separate the field. Runners who have been disciplined through the ascent can switch into a competitive gear on the descent and final stretch to Birkat Al Mouz. Give yourself a concrete target for the back half — a time split, a group to chase, a landmark to reach — and commit to it. Managed aggression in the closing 40 km is far more productive than early heroics that leave you shuffling the descent.
Fueling & Hydration in the Heat
Oman's mountain environment presents a fueling challenge that is unlike most European ultras: the combination of heat, low humidity and high altitude can suppress appetite while simultaneously accelerating fluid and electrolyte loss. Scale your caloric intake to your actual effort and the ambient conditions rather than following a fixed schedule. In the cooler, higher sections of the course, your burn rate drops and your gut can handle more; in the heat of the lower sections, less food and consistent sips of fluid will serve you better than forcing calories. If your stomach rebels mid-race, the answer is almost always to back off intake, not increase it — your energy reserves will carry you further than you expect even when eating slows. Prioritise electrolytes throughout, and plan your water carries carefully between checkpoints given the desert-mountain environment.
Conditions to Expect
Oman by UTMB takes place in a desert-mountain climate where temperatures can swing dramatically between the exposed high ground and the lower wadis. At the 2,267 m high point, conditions can be genuinely cold overnight, with wind chill adding to the challenge on ridgelines; the descent back toward 598 m at Birkat Al Mouz re-introduces heat, especially if the final kilometres are covered in daylight. Sun exposure on open terrain is significant — sun protection, a buff and sunglasses are essential kit for any daylight hours on course. The cut-off at Birkat Al Mouz of Day 13:00 gives a clear time target, but runners should plan their effort around the conditions rather than the clock alone. Break the heat and distance into manageable segments mentally — commit to the next section, reset, and move forward.
