Lace up and join us for a special X-Bionic Community Trail Run, co-hosted with X-Uetli on Zurich’s most unforgiving playground.

We meet at 10:00 am on Saturday, January 31, starting from Albisgütli, and take on the exact loop that will define the first-ever X-Im!possible Backyard Ultra this April. This is your chance to experience the course before race day.

Our second community run will start from the X-Bionic headquarters for an evening session up to the Uetliberg and back.

We meet at X-Bionic HQ in Zurich and start running at 6:30 pm on Tuesday, March 10, 2026 (arrive by 6:00 pm if you’d like to test the TerraSkin® trail running system).

An evening run open to everyone, with different routes and paces available. Please bring a headlamp, as we’ll be running after sunset.
