Spencer Matthews

Spencer Matthews is an endurance athlete, entrepreneur, and health advocate who specialises in translating extreme physical and mental challenges into actionable strategies for resilience and high performance. He holds three Guinness World Records, including completing Ironman-distance triathlons on all seven continents in just 21 days through his PROJECT SE7EN challenge, now the subject of a Disney+ documentary. As founder of CleanCo, an award-winning non-alcoholic spirits brand, and director of The Michael Matthews Foundation, Spencer combines athletic achievement with entrepreneurial success and charitable impact. His presentations equip audiences with practical tools to embrace discomfort, maintain focus under pressure, and pursue ambitious goals with renewed confidence and clarity.

In 2024, Spencer Matthews completed seven full-distance Ironman triathlons across all seven continents in just 21 days, 9 hours, and 18 minutes, shattering a world record previously held at nearly four years and setting three Guinness World Records in the process. The challenge, known as PROJECT SE7EN, pushed him through extreme climates, relentless time zone shifts, and physical depletion so severe that during one leg he questioned whether he could continue. That same year, he ran 30 marathons in 30 days on sand, and has conquered some of the planet's most demanding ultramarathons, including the Jungle Ultra and Marathon des Sables. His achievements have captured global attention, with Disney+ commissioning a feature-length documentary titled Breaking Spencer Matthews to chronicle his extraordinary feats of endurance and the mindset required to achieve what most consider impossible.

Spencer's credibility extends well beyond athletic accomplishment. As founder of CleanCo, an award-winning non-alcoholic spirits brand now sold globally, he has built a successful business rooted in his personal journey towards healthier lifestyle choices. His entrepreneurial success demonstrates the same discipline and strategic thinking that fuel his endurance challenges. Spencer also serves as director of The Michael Matthews Foundation, which educates thousands of disadvantaged children in Africa, and has raised hundreds of thousands of pounds for charities including James' Place, a male suicide prevention charity. Through his UNTAPPED podcast, he explores how individuals from diverse backgrounds have overcome obstacles and discovered their own potential, offering audiences insight into the psychology of sustained success. His work across business, philanthropy, and media reflects a commitment to translating personal experience into tangible impact for others.

Spencer equips audiences with actionable tools to develop resilience, embrace discomfort, and maintain focus under pressure. His presentations blend raw honesty about the mental and physical battles he has faced with practical takeaways that teams can apply immediately. He helps organisations understand how small shifts in mindset can lead to significant breakthroughs in performance and wellbeing, drawing on moments when he has been utterly depleted yet found ways to keep moving forwards. Whether speaking to corporate leaders, sales teams, or community groups, Spencer delivers messages that resonate long after the event, inspiring individuals to redefine their limits and pursue ambitious goals with renewed confidence and clarity. His ability to connect extreme challenge with everyday application makes him a powerful catalyst for lasting change.
