Travel advice - below we outline the best transportation options to get you to the event:

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.

Check-in! : We will be asking all registered participants to check in online approximately two weeks from the event. The Check-in process will result in a simpler event experience for you by removing the usual on-the-day administration. Within the Check-in process, we will ask you to 1) Confirm your preferred postal address to enable your participant number to be posted out, and 2) Watch the mandatory event safety video.

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, descends the Grimentz valley and climbs to the summit of the Corne de Sorebois mountain (2986m / 9501ft). Needless to say, this route isn't for the faint-hearted!

Geneva airport is just a couple of hours drive away and with 18 UK airports offering direct low-cost flights it couldn't be easier! Come and join us this September for some unforgettable trail running.

Entries are limited to just 150 participants.
