Heather Jackson, a former IRONMAN triathlon champion, made history with a record-breaking performance at the 2024 Unbound Gravel XL race — a grueling 350-mile endurance event often referred to as the “Kona of Gravel Racing.” In a stunning display of athleticism, resilience, and tactical acumen, Jackson crossed the finish line with a time of 26 hours and 20 minutes, setting a new course record in the women’s category and cementing her status as a top competitor in the gravel cycling world.

The Unbound Gravel XL, held annually in Emporia, Kansas, is one of the most challenging ultra-endurance gravel bike races in the world. Unlike the main Unbound 200-mile race, the XL format pushes riders to their absolute physical and mental limits over an extended, unsupported 350-mile journey through remote, rugged Flint Hills terrain. Riders must rely on their own strategy, navigation, and stamina to survive the long day—and night—on the saddle.

Jackson, who transitioned from triathlon to gravel racing just a few years ago, has rapidly ascended the ranks of this burgeoning sport. Her background as a professional triathlete and multiple-time IRONMAN podium finisher gave her a unique endurance base, but it was her adaptability and relentless drive that truly propelled her to victory in this ultra-distance format. In the 2024 XL race, she not only faced steep climbs, technical descents, and unpredictable weather, but also had to manage navigation and nutrition without any on-course support—hallmarks of the self-supported gravel racing ethos.

From the very start of the race, Jackson maintained a steady pace, carefully balancing speed with the need to preserve energy over the 26-hour journey. While other riders surged ahead or faltered due to mechanical issues or exhaustion, Jackson stayed remarkably consistent. She rode much of the second half of the race solo through the night, a true test of mental fortitude as temperatures dropped and fatigue set in.

Her final time of 26:20 not only broke the women’s course record but placed her impressively among the top finishers overall, regardless of gender. This performance marks a significant milestone in her evolving cycling career and signals a potential new era for gravel racing, where former triathletes and endurance athletes are increasingly making their mark.

After the race, Jackson credited her preparation, mental toughness, and the support of the gravel racing community. “This was one of the hardest things I’ve ever done,” she said. “But also one of the most rewarding. The solitude, the challenge, the beauty of the Flint Hills—it’s what makes this race so special.”

Heather Jackson’s victory at Unbound Gravel XL showcases not only her individual excellence but also the growing popularity and legitimacy of gravel racing as a premier discipline in endurance sports. With this win, she joins the ranks of elite athletes redefining what’s possible on two wheels—and her journey is far from over.
