Summary

As Dave and James recover from illness and injury, Ronan sits down with EscapeCollective member Marc Graveline to make sense of Jonas Vingagaard's stage 16 time trial performance. Marc was a data engineer before early retirement allowed him the time to moving into cycling and develop the Notio Konect, the first consumer available aero sensor on the market. Marc is now a consultant to World Tour teams and counts time trial modelling and analysis among his favourite hobbies, not to mention aero testing some of the world's best riders. Finally, we wrap the conversation with a discussion on what the other World Tour teams can do to narrow the gap to Jumbo-Visma.
