4th Edition

Bison Ultra | 10 Sep, 2023 | SUN


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.
