Robbie Britton

British 24-Hour Record Holder | Ultra Endurance Coach & Athlete

In February 2023, Robbie Britton ran 277.439 kilometers — 172.392 miles — in a single day in Turin, Italy. He ran in 1-kilometer circles, lapping Ruffini Park for twenty-four consecutive hours at an average pace of 5:11 per kilometer, breaking a British 24-hour record that had stood for forty-one years. The record had been set by David Dowdle in 1982. Robbie had been chasing it for a decade. The moment he crossed the line, he collapsed. He described it afterward as the hardest thing a human body can do. Robbie Britton is a British 24-hour record holder, one of the most respected ultra-endurance coaches in the world, and a man who has turned the philosophy of suffering into a professional science. He is a UKA Athletics Coach, holds an MSc in Performance Coaching and an IOC Sports Nutrition postgraduate diploma, and is a member of the Great Britain and Northern Ireland 24-hour team management. He began coaching professionally in 2013 and has worked for over fifteen years in ultra-distance running and cycling — starting when he quit his last tutoring job after competing in the World 24hr Championships and discovering that coaching gave him both the flexibility to train and the intellectual challenge of a second career. He is also the author of 1001 Running Tips: The Essential Runner's Guide, a must-read for anyone serious about the discipline. But Robbie's authority is not built on credentials alone. It is built on the specificity and intimacy of what he has put his own body and mind through. He knows what a 24-hour race does to a human being — because he has done it multiple times, at world championship level. He knows what it means to run when the legs are broken and the mind is screaming to stop — because he has been there. He finished third at the World 24hr Championships in 2015, covering 261 kilometers. He set the Fastest Known Time on the 650km Jordan Trail in 2019. He won the Wicklow Way 127km in 2019 with a course record. He has represented Great Britain at four World and European Championships. Now based in Italy — where, as he notes with characteristic dry humor, his British name becomes "Brighton" in Italian pronunciation — Robbie trains some of the finest ultra-endurance athletes in the world while simultaneously preparing himself for the 2025 World 24hr Championships. His philosophy is precise: "Simmer, don't boil." You cannot win a 24-hour race in the first half. You can only lose it. The entire strategic architecture of ultra-endurance, Robbie argues, is about learning to sustain the right effort for the longest possible period — not maximizing effort at any single moment. This principle applies not just to racing but to training, to recovery, and to the mental management of discomfort over time. Robbie Britton joined Mornings in the Lab's Center Stage because of a video — his teammate showed it to the hosts — of Robbie crossing the 24-hour line and collapsing. The question that generated the invitation was simple: how do you train your mind to get to that point? Robbie's answer, across the full arc of the conversation, is the reason this episode exists.

What is Robbie Britton's coaching background and expertise?

Robbie Britton has been a professional endurance coach since 2013, specializing in ultra-distance running and cycling. He holds an MSc in Performance Coaching and a postgraduate diploma in Sports Nutrition from the International Olympic Committee. He is a UKA Athletics Coach and serves on the management team for British Athletics' 24-hour squad. He began coaching to support his own athletic career but went full-time after his 2013 World 24hr Championships appearance.

He is also the author of '1001 Running Tips: The Essential Runner's Guide,' widely regarded as a definitive resource for serious runners.

What is Robbie Britton's 'simmer, don't boil' philosophy for ultra-endurance?

Robbie Britton's 'simmer, don't boil' philosophy is the strategic core of 24-hour racing and, he argues, ultra-endurance in general. The principle holds that the goal is to sustain the maximum effort that can be maintained across the entire duration — not to maximize output at any single moment. In 24-hour racing, there is no finish line to count down, no terrain change to reset the mind, and no way to 'work harder' to get to the end faster. The only winning strategy is to find the effort level that can be sustained for 24 hours and hold it — simmering, not boiling. This philosophy applies to training periodization, race-day execution, and the mental management of discomfort over time.

How does Robbie Britton train the mind for ultra-endurance racing?

Robbie Britton's approach to mental training in ultra-endurance is built on the reality that psychological challenges in 24-hour racing are inseparable from physical ones. Knowing that legs will hurt from early in the race, that there are still 18 hours to go, and that the clock moves at the same pace regardless of effort — these are facts that must be accepted and integrated, not fought. Robbie prepares his athletes and himself by rehearsing the mental states that will occur, developing emotional tolerance for discomfort, and building the specific mental skill of continuing to move when every signal says stop. He appeared on Mornings in the Lab's Center Stage specifically to address the question: how do you train your mind to get to that point?

What happened when Robbie Britton set the British 24-hour record in 2023?

In February 2023, Robbie Britton competed in the 24 Ore di Torino in Turin, Italy — a 24-hour continuous race run in 1-kilometer laps around Ruffini Park. He covered 277.439 kilometers (172.392 miles), breaking David Dowdle's 41-year-old British record of 274.480km. After finishing, Robbie collapsed at the finish line. He described the record as 'a dream come true' and acknowledged the psychological battle was as hard as the physical one — with legs beginning to hurt early and 18 hours still to run. The achievement was the culmination of a decade-long pursuit of the record. He was fueled by 90 grams of carbohydrates per hour and wore Nike AlphaFlys throughout.

It is particularly valuable for ultra-distance runners who need guidance on the specific demands of events beyond the marathon.
