Best Trail Running Trails

Now that we have covered the top trail races in Switzerland, let’s take a look at some of the best trail running trails that will put your running shoes to the test. Something to bear in mind when picking trails in Switzerland, not every hiking trail is a good running trail, so be cautious of this.

Gorges de l’Areuse, Jura Mountains

The Gorges de l’Areuse trail takes you through the beautiful Jura Mountains. It begins in the village of Chambrelien and then you will pretty much run through forests and then in the gorge the whole way, crossing the river on the pretty little bridges along the way. It is a part of the Jura Crest Trail and ends in Chambrelien, where you started.

The trail is 21 km long and has an elevation gain of 1,050 meters. As it is in the lower altitude of the Juras it is a great trail to run during the spring and fall while the trails in the Alps are still covered in snow.

Bettmeralp Trail

This is a stunning loop trail that runs alongside the Great Aletsch Glacier in the Jungfrau-Aletsch UNESCO World Heritage site of the Bernese Oberland. The scenery is one of a kind and it is one of THE trails not to miss in Switzerland.

The trail starts at Bettmersee Lake and over 22 km plus 848 km of elevation gain, you will pass by Blausee Lake, the Aletsch Glacier (the biggest in the Alps), Märjelensee Lake, and see amazing views of famous peaks including the Matterhorn before descending through forests back to Bettmeralp.

Klöntalersee Trail


This is a lovely trail that is close to Zurich and takes you around the stunning Lake Klöntalersee. The trail begins on the shores of the lake and then goes for 21 km and has 1,1142 meters of elevation gain.

You will see lovely waterfalls and the rocky wall of the Glärnisch massif as you run around the lake through alpine pastures and shady forests. There are some challenging ascents along the way and you can always stop for a refreshing swim in the lake whenever you need to.

Sitting at a low altitude, you can do this trail any time between April and November as it stays clear of snow.

Best Time for Trail Running in the Swiss Alps

While trail running in the Swiss Alps is pretty magical it also comes with its challenges and one of the most dangerous parts to deal with is the changeable mountain weather. It is therefore very important to pick the right time of year to go trail running in the Alps.

The window for trail running in the Alps also depends on the altitude you intend to run at. Higher altitude trails open later in the warmer months and close earlier, as one would expect.

Generally speaking, you can trail run in the Alps between May and November. May is a great time to access the lower-altitude mountain trails and there are fewer crowds too but the weather can be unpredictable.

The weather in June is more consistent and usually, you are blessed with blue skies. The high-altitude trails also open up in June, and there are not many crowds either.

July and August are the best weather conditions for hitting the trails in the Alps but you will have a lot more crowds to contend with.

September is pretty much the same as June. Consistently good weather, higher trails are still open, and the crowds are few and far between.

October and November are lovely as you can get to see the autumn colors in full bloom. However, the weather is unpredictable and can be quite bad. Also, the higher altitude trails will be closed so you will have to stick to the lower ones.

Overall, the best months to trail run in the Alps are June and September as the high-altitude trails are open, the weather is good, and there are fewer people out hiking/running.

However, if you want to hit the super high altitude trails around places like Zermatt, for example, July and August are the best times to do so.

Frequently Asked Questions

What is Alpine trail running?

Alpine trail running, as you might have guessed, is running in an alpine environment and that means in the mountains.

Being in the mountains, alpine trail running is a lot tougher than trail running at low altitudes. Runners have to tackle serious elevation gains as they go up ridges, mountains, and back down again.

The terrain is not easy either as the trails are often loose, have some serious drop-offs, and can be quite dangerous. When you add in the changing weather you find in the mountains along with the thin air at high altitudes, you have a serious challenge.

But, alpine trail running does not come without its rewards. The views from mountain tops across the peaks, valleys, and lakes are sublime.

Is trail running hard on knees?

Yes, trail running can be hard on the knees as they absorb a lot of impact when you are running, especially downhill.

It can increase the risk of knee injuries but a lot of experts say this is more likely due to improper running form or not having the right muscles in the right places before trail running.

Is Trail Running harder than street running?

Whether trail running is harder than street running depends on a lot of things. The main difference is the uneven terrain compared to a smooth flat surface, but on uneven tracks, you run slower than you would on a road, so perhaps they balance each other out in this regard.

Navigating the tricky routes of trail running is a lot more mentally challenging than street running, as you have to stay focused all the time. While street running, you can get into a meditative state and a great rhythm without much worry whatsoever.

There is some debate as to whether street running is harder on your knees than trail running, as the surface is a lot harder and has more impact on your knees. However, experts say that knee issues are a result of running form, muscle strength, and existing injury more so than terrain.
