The Endurance Hunter's journey started at the youthful age of 7 years old. While most kids Hunter's age were busy playing with play-doh, Hunter was getting ready to redefine logic and test what kids are truly capable of! After years of watching his dad participated in endurance adventure races, hunter constantly begged his father to let him join in on a race. At first, Jeff (Hunter's Dad) was very reluctant with the idea, he said that it was impossible for a kid to do an endurance race. Jeff looked around at all his fellow competitors and noticed there wasn't a single kid out there let alone someone even in their 20s, even today most people in endurance sports are well into their 40s. This didn't discourage Hunter but fueled him even more, he eventually convinced his dad to let him do a 6-hour adventure race!


From that very first race Hunter continued to push the limits that were placed on what a young person can accomplish. He went on to set his first World Record by becoming the Youngest Finisher of the 24 Hour National Championship at the age of 11 when the previous record holder was 23 years old. Hunter didn't stop there, he kept questioning what a kid could really do and went on to set multiple other World Records including being the Youngest Finisher of Adventure Racing World Championships and The Worlds Toughest Race. After completing most of the toughest adventure races in the world, he started broading his horizons towards endurance mountain bike racing and Ultrarunning where he set dozens of records.
