Mandatory gear for ultra trail: complete guide 2026
Mandatory gear for ultra trail: complete guide 2026
24 out of 30 ultra trail races we analyzed in Spain require mandatory gear. Depending on distance and terrain, you’ll need between 6 and 19 items. Missing even one can mean immediate disqualification at bib collection or at a checkpoint during the race. The total cost of gearing up from scratch is around 320-870 EUR, though if you already run trail you’ll likely only need to spend 30-60 EUR to fill in the gaps.
We’ve analyzed the mandatory gear lists from every race in our database to create this guide. Here you’ll find what each type of race requires, which product we recommend in each category, and the most common mistakes runners make.
The 12 mandatory gear categories
Universal gear: required by almost every race
These four items appear most frequently in race regulations across Spain:
| Category | Races requiring it | Purpose | Recommended product | Price |
|---|---|---|---|---|
| Wind jacket | 88% | Protection from wind and cold at altitude | Salomon Bonatti WP | 110 EUR |
| Charged mobile phone | 67% | Emergency communication and GPS tracking | - | - |
| Emergency blanket | 67% | Hypothermia prevention during forced stops | Lifesystems Thermal Blanket | 9 EUR |
| Emergency whistle | 63% | Acoustic signaling for rescue teams | Fox 40 Classic | 12 EUR |
The wind jacket is the king of mandatory gear: nearly 9 out of 10 races with a gear list require one. Not any jacket will do — it must be a technical, lightweight, and packable wind jacket. Many races specify it must be waterproof with a hood and sealed seams.
Emergency blankets are single-use: bring a new one for every race. Previously used blankets may have micro-perforations that reduce their reflective capacity. At 9 EUR each, it’s not worth the risk.
The whistle has a universal distress signal: three blasts, pause, three blasts. It’s one of the most commonly checked items at the start.
Distance-specific gear: what changes for ultras and night races
These items become mandatory when races exceed certain distances or include night sections:
| Category | When mandatory | Races requiring it | Recommended product | Price |
|---|---|---|---|---|
| Headlamp with batteries | Night ultras and 60K+ | 58% | Petzl Actik Core | 73 EUR |
| Reusable cup (150 ml+) | Cup-free races | 58% | Salomon Soft Flask 150 ml | 21 EUR |
| Hydration pack | Distances 30K+ | 46% | Salomon ADV Skin 12 | 92 EUR |
| Trail running poles | Varies by race and distance | 8% mandatory | Leki Ultratrail FX.One | 169 EUR |
Pay attention to poles: they are prohibited at Zegama-Aizkorri but mandatory for the 100K distance at Ultra Pirineu and at Travesera de Picos de Europa. Always read the specific regulations for your race.
For headlamps, look for at least 200 lumens and enough battery life for the full night. At Gran Trail Aneto-Posets 105K and Tenerife Bluetrail 110K, two headlamps are required.
Weather gear: technical clothing for mountain conditions
Technical clothing layers become mandatory in races at altitude, during autumn-winter, or with variable weather:
| Category | Typical condition | Races requiring it | Recommended product | Price |
|---|---|---|---|---|
| Waterproof rain jacket | Atlantic climates, high mountains | 17% | Gore Wear R7 GTX Shakedry | 120 EUR |
| Long-sleeve thermal base layer | Night races, altitude 2,000 m+ | 25% | Odlo Active Warm Eco | 40 EUR |
| Thermal gloves | Autumn-winter, altitude | 21% | Salomon Cross Warm Glove | 30 EUR |
| Thermal beanie or buff | Temperatures below 10 °C | 13% | Buff Thermonet | 21 EUR |
| Long tights | Nights at high altitude | 4% | Salomon Cross Run Tight | 20 EUR |
What’s the difference between a wind jacket and a rain jacket? The wind jacket blocks wind and repels light rain. The rain jacket has sealed seams and withstands prolonged rain. Races like Gran Trail Peñalara require both.
What each type of race requires
Not all races demand the same gear. We’ve grouped requirements by race type so you know what to expect:
| Race | Type | Mandatory items | Special rule |
|---|---|---|---|
| Zegama-Aizkorri | Skyrunning 42K | 1 | Poles prohibited |
| Ultra Sierra Nevada | Summer high-mountain ultra | 6 | Sun protection and altitude focus |
| Transgrancanaria | Long winter ultra | 6 | Headlamp for 128K and 83K |
| Ultra Pirineu | Autumn night ultra | 8 | Poles mandatory for 100K |
| Travesera Picos Europa | Technical mountain ultra | 8 | Poles mandatory, spare headlamp batteries |
| Gran Trail Aneto-Posets | Extreme vertical ultra | 19 | 2 headlamps, rear light, SPOT locator |
| Val d’Aran by UTMB | UTMB World Series ultra | 13 | 30L pack, bivvy, 800 kcal food reserve |
Gran Trail Aneto-Posets has the most mandatory gear in Spain: 19 items for its 105K distance, including a SPOT satellite locator and rear red light. At the other end, Zegama-Aizkorri only requires a lightweight wind jacket.
The 7 most common mandatory gear mistakes
-
Buying everything the day before at the start village. Shops get crowded, sizes sell out, and you have no time to test anything. Buy at least a month ahead and train with your gear.
-
Using brand-new gear on race day. A new pack can chafe, unadjusted poles can collapse, an untested headlamp can die. Use every piece of gear in at least one long training run.
-
Reusing an emergency blanket from a previous race. Emergency blankets are single-use. A blanket with micro-perforations loses reflective capacity. At 9 EUR, it’s not worth the risk.
-
Not reading the specific race regulations. Each race has variations. Poles are prohibited at Zegama but mandatory at Ultra Pirineu 100K. Mallorca by UTMB requires 1.5 L of water for its longer distances.
-
Skimping on the hydration pack. A bad pack causes chafing that costs you hours of suffering. It’s the most important investment after shoes.
-
Using a cheap headlamp with AAA batteries. They die halfway through the night and lack sufficient power. Invest in a rechargeable headlamp with at least 200 lumens and carry a spare battery.
-
Forgetting the whistle until bib collection. It’s one of the most commonly checked items at the start. Keep it accessible from the moment you pack.

- Check what you already have: verify condition (new emergency blanket, batteries charged, zippers working).
- Buy what you’re missing: don’t leave anything for the last day.
- Loading order: heavy items close to your back (hydration, food), light items in pockets (blanket, whistle).
- Accessibility: emergency blanket and wind jacket in quick-access external pockets.
- Take a photo: photograph everything laid out before packing. If you forget something at an aid station, you’ll know what’s missing.
