Challenge EPFL - ETHZ


The EPFL – ETHZ challenge is a ski competition that brings together both Swiss Federal Institutes of Technology : the EPF Lausanne and the ETH Zürich. It takes place each year in the end of the ski season in a Swiss ski resort, where 400 participants of both schools compete during 4 days. Participants need to be selected, and the selection process takes place until along the academic year. If you are passionate about winter sports and want to have incredible memories, join us !


Challenge in Numbers

4 Days of Skiing

During four days, challengers from ETH and EPFL compete on the slopes of a Swiss ski resort to get the annual trophy of Challenge.

450 Participants

In 2025, Challenge will gather 100 challengers (50 from ETH and 50 from EPFL), as well as 350 ex-challengers, staffs, organizers and professors from both schools.

After-Ski and Parties

Each day, a after-ski session is organised and a party with all the participants takes place in the ski resort. And of course, many surprises all along the event !
