X IM!POSSIBLE BACKYARD¹ – Teaser Run

Something big is coming. A Backyard Ultra like no other – possibly the most difficult in the world.
But before we tell you everything, we’re inviting you to discover the loop.

Join us on Saturday, September 20 at 9:00 AM at Albisgütli for a community run to preview the course. We’ll run the loop a couple of times together, at an easy pace – chat, laugh, climb, and feel the challenge.

The real madness starts in 2026.
Details and registration open later this year.

Curious? Show up on September 20 and find out why we call it the X IM!POSSIBLE BACKYARD.
