Damian Hall is an elite British ultrarunner, outdoor journalist, and climate activist who remarkably picked up long-distance running in his mid-30s. He quickly rose to international prominence, placing fifth at the prestigious Ultra-Trail du Mont-Blanc (UTMB) in 2018, winning the grueling 268-mile winter Montane Spine Race in 2023, and setting numerous Fastest Known Times across the UK. Hall is also a prominent figure at the infamous Barkley Marathons, reaching the final loop in 2023. Off the trails, Hall uses his platform to champion environmental sustainability. He co-founded The Green Runners, competes as a vegan athlete, and avoids air travel to reduce his carbon footprint. The Wiltshire-based father of two is also an acclaimed author, having written In It for the Long Run and We Can't Run Away From This to explore the intersection of extreme endurance and ecological responsibility.
