Oman by UTMB 2026 Guide: preparing for the Hajar Ultra 100M
The search name is Oman by UTMB, but the flagship race officially published for this brief is the Hajar Ultra 100M. The official site lists 154.601 km, 7,998 m of climb, a Thursday, December 10, 2026 start at 3:30 PM from Al Hamra, and a finish in Birkat Al Mouz before Saturday, December 12 at 3:30 PM. This is a serious hot-mountain ultra: long climbs in the Hajar, mountain nights, rocky footing, daytime heat and Omani logistics that begin as soon as you handle bib pickup.
Race overview
What makes Oman by UTMB hard is the constant contrast between desert and mountain. The race is not only about heat or only about vert. You have to manage long, rough climbs, exposed sections where you drink more than expected, and then higher segments where wind, night and fatigue demand a real layering and lighting system.
The other major theme is the point-to-point structure. You start in Al Hamra and finish in Birkat Al Mouz, with key route hubs around Sharaf Alalamain, Hail Aldiyar and Saiq. That forces you to plan travel, any crew support and your accommodation base around the race itself rather than as a simple destination weekend.

Preparation should mix mountain endurance, long hike-run climbs, durable descending, heat exposure and repeated rehearsal of the full pack. You need to test fluids, sodium, foods you can still tolerate in heat, night layers and especially the phone setup with active roaming, because that phone is part of the mandatory kit and the LiveTrail system.
Oman by UTMB / Hajar Ultra mandatory kit
The official mandatory list is long because the terrain and climate justify it. The right reading is to treat it as a complete desert-mountain system, not as a generic UTMB checklist.
- Running pack, smartphone with LiveTrail activated, international roaming enabled and phone reachable at all times, plus a minimum 2 litres of water.
- Closed trail shoes, first-aid kit, 1.40 m x 2 m survival blanket, whistle, two working torches with spare batteries, and a recommended 800 kcal food reserve.
- Hooded waterproof jacket rated at least 10,000 Schmerber, buff or head covering, a warm second layer, personal cup of at least 150 ml, passport or ID, and a reusable bowl.
- Depending on conditions, the hot-weather kit adds SPF 50 sunscreen, sunglasses and a Saharan cap; the bad-weather kit adds full-leg cover and an extra warm layer.
Bib pickup is mandatory in person with a gear check, either in Muscat on December 5-6 or in Birkat Al Mouz on December 8-9, from 10:00 AM to 10:00 PM.
Three gear choices that make sense for Oman by UTMB
On the Hajar Ultra, you need equipment that can absorb heat, rock, long nights and significant liquid carrying requirements.
Mafate X
A logical choice if you want protection on mineral terrain and strong tolerance once the descents become long and abrasive.
Open brand pageS/LAB Ultra 12
Relevant for carrying 2 litres, the desert-mountain mandatory kit, layers and calories without turning the upper body into a constant friction point.
Open brand page3-piece Carbon Folding Trail Running Poles
Very useful if you already know how to use them on the Hajar climbs while staying tidy through more technical sections.

Logistics to solve early
Bib pickup is already part of the project. It must be done in person with a gear check, either in Muscat on December 5 and 6 or at the Race Village in Birkat Al Mouz on December 8 and 9, from 10:00 AM to 10:00 PM. The official FAQ also says that most runners arrive via Muscat International Airport. That means the airport-to-mountains-to-race-village chain needs to be solved well before race week.
The course then moves through several practical anchor points: Al Hamra at the start, Sharaf Alalamain at 43.864 km, Hail Aldiyar at 89.195 km, Saiq at 124.8 km and Birkat Al Mouz at the finish. The organisers mention a dedicated shuttle service, but exact timings are released later, so keeping a rental-car or private-transfer backup is sensible.
Transport: Muscat first, then the Hajar and the Race Village
The official FAQ identifies Muscat International Airport as the natural gateway for most visitors. From there, the next job is the road transfer toward the Al Hamra / Birkat Al Mouz area.
Because the event is point-to-point, the real transport challenge is not only the airport ride. It is coordinating bib pickup, accommodation, access to the Al Hamra start and the post-finish exit from Birkat Al Mouz.
Accommodation: Muscat early in the week, Birkat or Al Hamra for the race
Muscat makes sense if you want to handle the first bib-pickup window and absorb long-haul travel calmly.
For the race itself, Birkat Al Mouz simplifies access to the race village and the finish, while Al Hamra reduces start-morning stress. Many runners benefit from accepting a split stay rather than forcing a single badly positioned base.
Race week timeline
Early week
Arrive in Oman, review the full mandatory kit, decide whether bib pickup happens in Muscat or Birkat Al Mouz, and absorb the climate rather than chasing useless late training volume.
Tuesday / Wednesday
Collect the bib between 10:00 AM and 10:00 PM, complete the gear check, confirm road or shuttle logistics and close the loop between Al Hamra and Birkat.
Thursday, December 10
Start at 3:30 PM from Al Hamra with a restrained approach to water, sodium and climbing, remembering that the first night arrives quickly.
Friday / Saturday
Move through Sharaf Alalamain, Hail Aldiyar and Saiq cleanly, protect the stomach and aim for Birkat Al Mouz before the 3:30 PM Saturday cutoff.
Turn the guide into action
Oman by UTMB becomes much more readable once you accept that the Hajar Ultra is a true desert-mountain race, not just an exotic UTMB stop. If you structure water, Muscat-Birkat-Al Hamra logistics and the night-layer system early enough, the project gains real clarity.
Oman by UTMB FAQ
Why does the guide talk about Hajar Ultra?
Because that is the official name currently published for the 100M race inside Oman by UTMB.
Is heat the main factor?
It matters a lot, but the race is really defined by the combination of heat, climb, relative altitude and long nights.
Is the phone with active roaming really mandatory?
Yes. The rules require a smartphone with LiveTrail activated and international roaming enabled for use in Oman.
How much water do I need to carry?
The official mandatory list sets a minimum of 2 litres, which shows how much autonomy the climate demands.
Where should I stay?
Muscat simplifies the early week and the first pickup window; Birkat Al Mouz simplifies the race village and finish; Al Hamra simplifies the start.
What is the main trap?
Underestimating the combined load of heat, rock, race length, bulky mandatory kit and point-to-point travel. Each part seems manageable alone, but the total cost rises fast.
