Gerês Marathon

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.
