GTPE Picos de Europa 2026 takes place on Saturday, June 27, with a decision that runners should make before looking only at distance: which race actually fits your experience, preparation and ability to handle elevation? The event, starting and finishing in Benia de Onís, Asturias, offers five main options, from the 10 km Speed Trail to the 70 km ultra through the western massif of the Picos de Europa.
The appeal is obvious: Asturian mountain terrain, one of Spain’s great trail-running settings, and courses with real character. But that is exactly why the choice should not be driven by ego or by comparisons with road racing. At GTPE, elevation gain, cut-offs, semi-self-sufficiency, mandatory kit and mountain weather matter as much as kilometres.
What races are included in GTPE Picos de Europa 2026?
According to the official GTPE Picos de Europa website, the 2026 edition is held on June 27 in Benia de Onís and includes five distances. The event is presented as a trail-running race in the Picos de Europa with options for very different runner profiles.
- 70 km: 06:00 start, 5,300 m of elevation gain, highest point at 1,890 m on Jultayu and a 18.5-hour time limit.
- 48 km: 08:30 start, 2,700 m of elevation gain, highest point at 1,279 m on Porra de Enol and an 11-hour time limit.
- 35 km: 09:30 start, 2,200 m of elevation gain, highest point at 1,042 m on Camba and a 9-hour time limit.
- 22 km: 09:00 start, 1,383 m of elevation gain, highest point at 1,042 m on Camba and a 6-hour time limit.
- 10 km: 10:00 start, 500 m of elevation gain, highest point at 539 m on La Cal and no listed time limit.
The 321Go registration page lists prices of €110 for the 70 km, €80 for the 48 km, €65 for the 35 km, €45 for the 22 km and €25 for the 10 km. It also shows registration closing on June 23, 2026 at 23:59, or earlier if places sell out, for several categories; at the time checked on June 23, the 10K appeared as full.
The 10K is not a stroll: it is an entry point to trail
The 10 km Speed Trail is the logical option for runners coming from road races, those with limited hill training, or anyone who wants to experience a mountain setting without committing the whole day. Its 500 m of elevation gain already changes the rhythm completely: this is not a fast road 10K, but a short trail race where hiking steep sections can be the smart move.
It suits runners who have experience with 5K or 10K races, some comfort on paths and a desire to test shoes, climbs, descents and effort control without hard cut-offs. Still, it is worth arriving with trail-appropriate footwear, some downhill practice and a hydration plan, because mountain races do not reward improvisation just because the distance looks manageable.
22K: only half-marathon-like on paper
The 22 km race may tempt runners who have completed half marathons, but that comparison can mislead. With 1,383 m of elevation gain, the effort is much closer to a serious mountain race than to 21 km on the road. The official time limit is 6 hours and the regulations include cut-off points at La Berruga, Camba and the finish.
This is a good choice for runners who already train on climbs, can manage long uphill sections without overreaching, and can descend without destroying their legs. If your main reference point is a flat half marathon, the question is not whether you can cover 22 km. It is whether you can sustain several hours of uneven effort over changing terrain and possible mountain conditions.
35K: the pivotal distance
The 35K may be the trickiest distance to choose. It does not carry the mental label of an ultra, but it includes 2,200 m of elevation gain and a 9-hour time limit. The organiser describes it as a route through the lower mountain passes of Onís, the Casaño river gorge and La Molina.
It can fit runners who have already completed 20-25 km trail races and who have trained long outings in the mountains. There is also a pairs category, according to the regulations, which changes the strategy: pairs must run together and cannot be separated by more than one minute. For many recreational runners, the 35K is where pace stops being the main variable and management takes over: eat early, avoid reckless descending, reach Camba in control and save enough legs for the return.
48K: for runners who already know long mountain days
The 48 km race raises the commitment: 2,700 m of elevation gain, an 08:30 start and an 11-hour time limit. It is the smaller sibling of the ultra, but that does not make it an easy middle option. The accumulation of kilometres, cut-offs and the terrain of the Picos de Europa require genuine long-trail experience.
It belongs on the shortlist for runners who have completed mountain races around marathon distance, know how to fuel during prolonged efforts and do not need to feel comfortable all day. If you are choosing between 35K and 48K, look at your longest specific outing in the past eight weeks. If you have not spent several hours on technical or sustained mountain terrain, the jump may be too large to enjoy.
70K: an ultra with its own rules
The 70 km GTPE Ultra is a different conversation. With 5,300 m of elevation gain, a 18.5-hour limit and a highest point at 1,890 m, it becomes a challenge of endurance, patience, kit and effort management. The official distance page says the route passes landmarks such as Ruta del Cares, Canal de Trea, Jultayu, Vega de Ario and Lagos de Covadonga.
The official regulations add important details: the race is semi-self-sufficient, there is a neutralised section on Ruta del Cares where running is forbidden, specific cut-offs apply, and a medical certificate is required only for the 70 km ultra. The organiser also provides a life bag at Entrelagos for the 70K.
This distance should be reserved for runners with previous ultra or long mountain-race experience. Road marathon fitness is not enough on its own. You need to know how to eat when appetite fades, manage cold or rain if it arrives, keep moving if the day stretches toward night, use poles if they are part of your plan, and accept that strong hiking can be more efficient than poor running.
Kit, water and semi-self-sufficiency
One of the key points in the regulations is semi-self-sufficiency. Each runner must carry enough food, drink, salts or supplements to complete the race, and containers for at least 1.5 litres of water are required. The organiser even recommends up to 2 litres for the 70K. Cups are not provided at aid stations, so carrying your own cup is mandatory.
For the 70K, mandatory kit includes mountain-running shoes, a waterproof and breathable hooded jacket, a thermal top or equivalent combination, long tights or an accepted alternative, gloves, a headlamp with spare batteries, survival blanket, water container, cap or visor, food reserve, charged mobile phone and cup. For the 48K, 35K, 22K and 10K, the cup is the basic mandatory item, although the organiser may add a survival blanket, windproof jacket and charged phone if the weather forecast requires it.
How to choose without getting it wrong
- Choose 10K if you come from road running, want to try trail or have not trained elevation consistently.
- Choose 22K if you already run on mountain terrain, handle long climbs and want a demanding race without stepping into ultra-distance territory.
- Choose 35K if you have completed 20-25 km trail races and have experience managing food, descents and muscular fatigue.
- Choose 48K if you already know how to spend many hours in the mountains and have recent specific long outings.
- Choose 70K only if you have ultra or long mountain-race experience and can manage kit, medical certificate, cut-offs and fueling strategy.
The best choice is not the most heroic distance. It is the one that lets you respect the terrain and reach the finish with an experience you would want to repeat. In the Picos de Europa, choosing well is part of running well.
