A Message from the Race Director

9th Bison Ultra • 6-Jun-2027

Dear Bison Ultra runner,

Bison Ultra is our quieter, estate-trail sibling to OOTYULTRA — an intimate trail experience through the Shevaroy Hills where every climb is earned and every view is a reward.

If you also follow OOTYULTRA: the 9th edition is on 22-Mar-2026 (Sunday) with 90k, 75k, 60k, 50k, 30k, and 15k distances. You can register here: ootyultra.com/register.

This year we return to Gowri Estates with limited on-venue stay capacity and a focused race-weekend experience at Heavens Ledge. If you’re new to trail ultras, come prepared, pace with patience, and lean on the community.
