Marten Van Riel Previews the Nice Ironman World Championship

This week on All In Triathlon, we’re joined by Belgian star Marten Van Riel as he gears up for the Ironman World Championship in Nice. Marten opens up about the ankle injury that nearly kept him from even making it to the start line, and the mental battles that come with being sidelined. He shares how he managed the setbacks, rebuilt his confidence, and found his way back into race shape.

Looking ahead to Sunday, Marten gives an honest assessment of his goals, the tactics he’ll bring to the French Riviera, and who he sees as the biggest rivals in the field. He also offers a detailed course breakdown—covering the technical bike, challenging climbs, and what it will take to run well on the Promenade des Anglais.

Whether you’re racing in Nice yourself or following along from home, this is a must-listen inside look at one of triathlon’s best as he takes on the sport’s biggest stage.
