  • Limited accommodation slots are available, and they will be allotted on a first-come-first basis.  Additional charges may apply to access the venue if you decide to stay elsewhere (or after the accommodation quota is exceeded).  The Heavens Ledge/Last Shola management decide this.
  • The estate owners decide the accommodation + food or the entry fee, and the Bison Ultra organizing crew or anyone from KaysFIT Academy does not interfere in the registration process. 
  • All runners must comply with the resort rules, booking terms, and conditions.
  • Accommodation bookings will start from 4-Oct-2023.

Bison Ultra is a dream trail ultramarathon conceptualized by Coach Kay, founder of KaysFIT Academy & OOTYULTRA. The first edition was successfully conducted on the 9-Feb-2020 Sunday, in the most mesmerizing and unexplored terrains in Yercaud.  

Yercaud, like Ooty, is home to large Indian Bison (also the tallest of the wild cattle family), otherwise called Wild Gaur; some of them are as tall as 220 cm.

After OOTYULTRA, with a singular focus to bring in the best experience to the ultra trail-loving runners, this is the first time Coach Kay has ventured into organizing an exclusive trail marathon like this.
