Gut training has become one of the buzzwords in endurance sport, but is it hype or a real performance advantage? In this episode of Performance Process, Ronan Mc Laughlin is joined by accredited sports dietitian and endurance nutrition researcher Dr Alan McCubbin to break down what gut training really is, why it matters for cyclists, and how to apply it in the real world.

From the science behind carbohydrate absorption and fluid tolerance to the practical protocols used by pros, they explore how to reduce gut discomfort, handle higher carb intakes, and adapt your digestive system for race-day demands. The podcast discusses much of the same topics Dr McCubbin covered in his article Gut training for cyclists: What is it and how can we do it? on EscapeCollective.com last month.

Performance Process is back after a Tour de France-shaped gap. In this episode, CyclingSpy returns to unpack the most intriguing performance trends from the Tour de France and Tour de France Femmes. From new helmet wars and front versus rear zippers, to sprinter aero testing and the mountain time trial that became a masterclass in simulation modelling and equipment selection, we explore how optimisation is shifting from behind-the-scenes intervention to full-blown marketing strategy. Plus, we tackle your questions on oversized chainrings and wet weather aero.

In this special Performance Process x Geek Warning crossover, Dave Rome grills Ronan Mc Laughlin about every technical detail from his 3,000 km unsupported lap of Ireland. From aero bag hacks and drivetrain quirks to cleat regrets and a failed light, this is a deep dive into the tech setup behind a truly personal and punishing ultra-endurance ride. Ronan shares what worked, what didn’t, and what he’d change next time – all while reflecting on how the gear supported his mission to raise awareness for food allergy research.
