truefuels ran a study at Leeds Beckett measuring where 200 watts of energy at 200 watts goes, using CoreCtrl or a dummy sachet at 37°C with a fixed heat load per athlete over eight days.

truefuels was born from Alistair Brownlee’s relentless pursuit of peak performance. As a two-time Olympic champion and one of the greatest triathletes ever, he spent decades refining his nutrition to fuel endurance, recovery, and resilience. Partnering with co-founder Goran, but also top food scientists, including Chief Scientific Officer Nigel Mitchell, Alistair transformed this elite knowledge into truefuels—science-driven, athlete-tested fuel designed to help ambitious athletes push their limits. Built in the lab, proven on the road, truefuels delivers optimised energy without compromise. Because when every detail matters, only the best fuel will do. Be your best!
