UTMB World Series Experience

Competing at the front of UTMB World Series events gives Brennan a direct and practical advantage as a coach. He understands exactly what it takes to perform on the most demanding courses in the world — from pacing and fuelling to technical descending, climbing efficiency and race execution under fatigue.

For the athletes he coaches, this translates into real-world insight, not just theory — helping them prepare effectively, avoid common mistakes and perform with confidence on race day, whether they're stepping up to their first ultra or targeting high-level competition.
