After an extremely successful 2023 event we are delighted to launch today "Endurancelife Lac de Moiry 2024!"

For those travelling from further afield below are a few pointers about how best get to this location:

By air

The closest international airport is Geneva (GVA) - Skyscanner link

By car

This is the easiest way to navigate to the event. Event parking is situated by the Glacier de Moiry, Grimentz, 3961, Switzerland.

By train

The closest train station for the event that is served by long-distance trains is Sierre/Siders. From Sierre/Siders, you can reach the event location using the bus network.

There are regular trains from Geneva Airport & Geneva (2 hours) and other European destinations.

By bus

The bus stop to disembark at is 'Moiry, glacier'. A network map is available here. There are limited bus options to get you to the event site in time for the start so please plan carefully.

We recommend staying in either Grimentz (29 mins journey) or Zinal (42 mins journey) if you plan to access the event by public transport as there is a direct bus (B 455) from both locations that will arrive at the event site in good time on the morning of the event.

Visit the SBB website for both train and bus schedules and tickets.

Lac de Moiry's notoriously turquoise blue waters are fed by fresh glacier melt during the summer months. Starting at 2249m (7378ft) above sea level and only 10 miles from the world-famous Matterhorn, this unique route showcases some of the very best of the Swiss Alps.

The fully waymarked 30 km route circumnavigates the phenomenal lake and descends the Grimentz valley before the relentless 1300m (4300ft) climb to the summit of Corne de Sorebois (2986m / 9501ft).

Needless to say, this route isn't for the faint-hearted! With an overall ascent of over 1900m (6200ft) in just 30Km, this truly is mountain alpine running and promises to be an unforgiving day on the trails!

Entries for 2024 are limited to just 150 participants.

Travelling from further afield? Geneva airport is just a couple of hours drive from Lac de Moiry so international travel couldn't be easier.

The closest train station for the event that is served by long-distance trains is Sierre/Siders. From here you can reach the event location using the bus network in under an hour.
