Ultra-distance cycling is often described as a solitary adventure. Riders spend days crossing countries, battling fatigue, weather, navigation and their own limits. But behind every Race Across Series event, there is an invisible system quietly working around the clock to keep the race safe, fair and under control.

It’s called the PGO — the Participant Guidance Office.

In this episode, Arnaud Manzanini sits down with Stéphane, the architect behind the technological evolution of the PGO, to take listeners inside the operational heart of the Race Across Series.

Together, they reveal how this system has evolved from simple notebooks and spreadsheets into a sophisticated monitoring platform capable of tracking hundreds — sometimes thousands — of riders in real time.

They discuss how the PGO team analyzes GPS data, monitors rider fatigue, manages alerts, and responds to calls ranging from simple navigation questions to medical support, unexpected incidents, or race rule enforcement.

But beyond the technology, this conversation highlights the human dimension of the PGO: a trained team working day and night, often remotely, making decisions that balance safety, fairness and respect for the spirit of ultra-distance cycling.

You’ll also discover some of the real stories that happen during races — from stolen bikes and roadside emergencies to unexpected acts of solidarity between riders.

Finally, Arnaud and Stéphane unveil the next evolution of the system, including a new Race Across Series mobile app designed to improve communication, deliver real-time race information and support riders even more efficiently during their adventure.

Because in ultra-cycling, even when riders feel completely alone on the road, they never truly are.
