About the Gerês Marathon 2025
The Gerês Marathon is part of a well-established trail running festival in Portugal. Each year, it attracts hundreds of athletes from different countries who want to run through one of the most beautiful natural parks in Europe. The 2025 edition will once again highlight the wild beauty of Gerês: crystal-clear rivers, lush forests, and rocky ridges.
The event usually offers different distances, from shorter races for beginners to the iconic marathon distance. The full 42 kilometers are the main challenge, with a route that mixes runnable paths and technical sections. Expect significant elevation gain, but nothing extreme compared with ultra-trail races.
The weather in Gerês can vary. In some editions, runners have faced rain and mud; in others, the sun has made hydration a key factor. This variability makes the race more authentic and requires preparation for all conditions.
Above all, the atmosphere is what makes the marathon special. The organizers and volunteers create a warm environment, and the local community welcomes participants with enthusiasm. Running here feels less like a competition and more like a celebration of trail running culture.
The course: what to expect
The Gerês Marathon 2025 route offers a full mix of mountain terrain. You will encounter forest trails, rocky climbs, steep descents, and open sections with panoramic views of the national park. The elevation profile includes long climbs that require patience and careful pacing.
Unlike a road marathon, where you aim to keep an even pace, here the strategy changes constantly. Some sections are runnable, while others require power hiking. The course will likely include technical terrain with stones and roots, so concentration is essential.
One of the highlights of the race is the constant contact with nature. Expect to pass by rivers, waterfalls, and small villages, creating moments that make the effort worthwhile. The scenery helps distract from fatigue and reminds you why trail running is more about experience than time.
For many, the biggest challenge is adjusting expectations. If your road marathon personal best is 4 hours, do not expect anything close here. Finishing between 5 and 6 hours is realistic, depending on weather and terrain conditions.
Pacing strategy for first-timers
Trail running pacing is different. Trying to maintain the same rhythm as on the road is a recipe for disaster. In the Gerês Marathon, smart pacing means starting conservatively and adapting effort to the terrain.
On climbs, do not hesitate to walk. Power hiking saves energy and is often faster than running uphill. Use your arms to push on your thighs and keep a steady rhythm. On descents, stay controlled. Running too aggressively can overload your quadriceps or lead to falls.
A good rule of thumb: focus on effort, not on pace per kilometer. Think in terms of “can I keep this level of breathing for several hours?” rather than checking your watch every minute. Many experienced trail runners even cover their pace display to avoid mental pressure.
Finally, save energy for the last 10 kilometers. In Gerês, the final section can feel long, especially if your legs are empty. A smart strategy is to think of the marathon as two halves: the first 30 km for patience, the last 12 km for courage.
Shoes and gear recommendations
Shoes are the most important choice for your debut in Gerês. Forget road models: here you need trail running shoes with good grip, cushioning, and stability. The terrain includes rocks, mud, and uneven surfaces. A sole with aggressive lugs will give you confidence in technical areas.
If you are planning to debut new shoes, this race is perfect. Just make sure you test them in training at least a few times. Never run a marathon with shoes straight out of the box.
In addition to shoes, consider bringing:
Hydration pack: aid stations are usually well placed, but carrying your own water and gels gives you independence.
Poles (optional): useful for steep climbs if you know how to use them.
Technical clothing: lightweight, breathable, and suitable for variable weather. A waterproof jacket can be essential if rain arrives.
Do not underestimate comfort. A good pair of socks, anti-chafing cream, and sun protection can be the difference between a great experience and a painful memory.
Tips for road runners transitioning to trails
If you come from the road, training for Gerês requires some adjustments. Start by adding trail sessions into your weekly plan. Even short runs on uneven ground will teach your body to adapt. Hill repeats are key. Both uphill strength and downhill control need specific preparation.
Strength training also becomes more important. Squats, lunges, and core exercises improve stability and reduce injury risk. Strong legs and a solid core will carry you over roots, rocks, and long descents.
Mentally, the biggest shift is letting go of pace obsession. In trail running, you can be walking and still be racing smart. Focus on effort, terrain, and enjoying the environment.
Nutrition is another key factor. Unlike road marathons, aid stations may be further apart. Practice eating and drinking while moving. Small sips and frequent energy intake keep you steady.
Race day advice and mindset
On race day, arrive early and take time to warm up. The first kilometers can be crowded, so starting calmly helps. Do not let adrenaline push you into a pace you cannot sustain. Respect the mountain from the beginning.
During the race, stay alert on technical sections. Look two or three meters ahead to anticipate obstacles. On climbs, keep a rhythm that feels sustainable. On descents, relax your body and let your legs flow without forcing.
The best advice is to focus on the journey. Trail running is not about chasing a personal best; it is about experiencing the trail and enjoying the community. Talk with fellow runners, thank volunteers, and embrace the challenge as part of the fun.
Remember: finishing strong is more rewarding than starting too fast and collapsing at the end.
