Al Hamra → Birkat Al Mouz
Race guide
Updated 19 July 2026
The Hajar Ultra 154K is the flagship distance at Oman by UTMB, routing runners 154 km from the ancient mud-brick village of Al Hamra to the palm-fringed oasis of Birkat Al Mouz, deep in the heart of the Al Hajar Mountains. With 7,417 m of cumulative gain and a high point of 2,400 m, this is no desert flat — the course threads through dramatic wadis, exposed ridgelines, and technical rocky terrain that demand respect from even seasoned ultrarunners. The 48-hour cut-off at the finish sets the tempo: this is a race that rewards those who manage their effort across a full two days and one night in the Arabian wilderness.
Course & Terrain
The route begins at Al Hamra (681 m) and immediately introduces runners to the Hajar Mountains' defining character: a relentless interplay between open wadi floors, sharp ascents onto rocky ridges, and technical descents on loose, sun-baked limestone. The early kilometres through valley terrain can feel deceptively runnable — wide lines, good footing, a sense of momentum — but the cumulative 7,417 m of climbing ensures the course never lets you forget its true nature. A notable Via Ferrata section arrives around the 87 km mark at 1,642 m elevation, adding a genuinely technical, hands-on passage that slows progress and demands focus mid-race when fatigue is already accumulating. The finish drops into Birkat Al Mouz at 598 m, meaning the final stretch is predominantly descending, but by then your legs will have absorbed nearly 100 km of hard mountain terrain.
Decisive Climbs & Where the Race Is Won or Lost
The race's character is shaped by the section beyond the halfway point, particularly the approach to and departure from the 2,400 m high point and the Via Ferrata at 87 km. The Via Ferrata is a psychological and physical inflection point: arriving there having spent too much in the first half means you'll grind through it rather than move with confidence. The descent from the high point back toward Birkat Al Mouz carries the potential for a strong finish — but only for runners who banked patience early. Those who push hard through the appealing early wadi sections invariably find the second half unforgiving. The race is decided not on any single climb but in the accumulated decision-making of the first 70 km.
How to Pace It
The single most important strategic insight for the Hajar Ultra 154K is that the early valleys are a trap. They feel free and flowing, and they are not. A social, almost relaxed first half is not a risk — it is the deposit that funds a strong second. Resist the urge to 'make time' on runnable terrain before the 87 km checkpoint; every minute banked in effort there is borrowed from your finish. Once through the Via Ferrata and across the high point, shift mentality: break the remaining distance into manageable resets rather than staring at the total kilometres left. Two checkpoints at a time, one ridge at a time. The 48-hour cut-off is generous enough for a thoughtful runner who starts patiently, but unforgiving for anyone who blows up in the heat of the first day.
Fuelling Strategy
With 154 km and up to 48 hours on course, fuelling is a two-day project, not a single-day effort. Prioritise eating real food in the early stages while your gut is cooperative and appetite is high — the Omani heat will suppress appetite as the day progresses, so front-load calories where you can. Hydration must be proactive: the desert environment and exposed ridgelines mean sweat rates are high even when the air feels dry. Sodium management is critical; plan for consistent electrolyte intake through the heat of the first day and into the night. As you push through the Via Ferrata section at 87 km and into the second phase of the race, shift to easily digestible fuels and prioritise consistent small intakes over large infrequent feeds. Never arrive at a checkpoint in a deficit.
Conditions to Expect
The Al Hajar Mountains of Oman present a unique environment: intense daytime heat on exposed ridges and reflective wadi floors, followed by genuinely cold nights at elevation near the 2,400 m high point. Runners must carry layers for the overnight section despite the desert setting — temperature swings between day and night can be significant, and fatigue amplifies the sensation of cold. Wind on the upper ridgelines adds a further chill factor. The rocky limestone terrain is hard underfoot throughout — cushioning and durable outsoles matter. Navigation demands attention, particularly on technical sections after dark. Dust and fine grit are constant companions; protect your eyes, feet, and any chafe points from the start.
