Mammoth Mindset

The intent of the Mammoth Endurance Triathlon series is rooted in the desire to watch you grow and succeed in the sport of triathlon; without the angst that other race series may bring about. With an intentional lower capacity, a high lifeguard to participant ratio, smaller course loops to maximize support and safety, and a dedicated team to educate you before and after the event itself - we have the tools and structure to assist you in reaching your goals.

The Course: Short Loops, Maximum Support

This course is uniquely designed using short, repeatable loops entirely within the boundaries of Oak Mountain State Park. This format ensures maximum athlete safety and constant encouragement from volunteers and fellow participants.

The beating heart of the Mammoth Series is its on-course Aid Station & Athlete Village. You will have access to your personal crew every loop, allowing for consistent refueling, gear swaps, and motivational boosts. You will be supported with real food made with care and an on site medical team.
