Gerês Marathon – the last chance of the year to debut in mountain running
The Gerês Marathon is one of the most accessible mountain marathons in Portugal. It takes place inside Peneda-Gerês National Park, a natural paradise with granite peaks, deep valleys, waterfalls and ancient shepherd trails. Because it happens late in the year, many road runners choose this event as their first experience in trail running and mountain terrain.
If you come from the asphalt world and want a smooth, friendly introduction to mountain events, this is one of the best options you will find.
Why the Gerês Marathon is perfect for road runners
1. A runnable course
Despite being a mountain marathon, most of the course is very runnable. Climbs are steady instead of steep, and technical sections are short. This helps road runners maintain rhythm and confidence.
2. Cooler, predictable weather
The late-season date usually brings mild temperatures. That’s a big advantage for athletes used to road training.
3. Wide trails and forest tracks
Large parts of the race take place on fire roads, panoramic gravel paths, and clean singletracks. These trails reduce the learning curve if you are not used to rocky or root-heavy terrain.
4. A very safe environment
The race is well marked and packed with volunteers. Aid stations are frequent and well prepared. For first-timers in the mountains, this level of support feels reassuring.
Course overview
The Gerês Marathon covers roughly 42 km with moderate elevation gain. You will face:
Long rolling climbs
Fast and enjoyable descents
A few short, rocky segments
Spectacular views of the national park
The terrain changes often, keeping the race fun without overwhelming beginners.
How to train if you come from road running
Add short hill repeats
They build leg strength and confidence. Begin with 20–30 second efforts and extend them gradually.
Practice downhill control
Downhills are where road runners lose the most time. Use short, fast steps and keep your upper body relaxed.
Include one or two trail sessions per week
Even minimal trail exposure helps you adapt to uneven surfaces.
Do basic strength work
Single-leg exercises, glutes, and core training improve stability and help prevent injuries.
Race-day strategy
Start easier than usual
The excitement and runnable terrain can make you go too fast early. Save energy for later climbs.
Fuel every 30–40 minutes
Cooler temperatures make it easy to forget to eat, so set a timer if needed.
Stay controlled on technical downhills
Do not force risky speed. Prioritize balance and clear foot placement.
Finish strong
The final kilometers are fast. If you save energy, you will pass many runners in the last stretch.
