Held annually in Kailua-Kona, Hawaii, this event attracts elite athletes from around the globe who come to test their limits across three demanding disciplines: swimming, cycling, and running.

The Ultimate Test of Endurance

The 2024 race will challenge participants with:

  • 2.4-mile swim: Athletes will start their journey in the open waters of Kailua Bay, battling ocean currents and waves.

  • 112-mile bike ride: Cyclists face intense heat and wind as they navigate Hawaii’s lava fields and rugged coastline.

  • 26.2-mile marathon: The final leg of the race takes runners through Kona’s arid, hot terrain, completing a full marathon under the extreme Hawaiian sun.

Competitors must complete all three legs in a single day, pushing their bodies and minds to the limit in this 140.6-mile course.

In 2024, Billy Monger will face his biggest challenge yet, competing in the legendary VinFast IRONMAN World Championship in Hawaii. Known for its grueling 140.6-mile course, the IRONMAN demands extraordinary physical and mental endurance, with a 2.4-mile swim in the Pacific Ocean, a 112-mile bike ride through rugged terrain, and a full 26.2-mile marathon across scorching lava fields. This race is an ultimate test of strength, but for Billy, it’s also a race with a purpose.


Billy Monger's story is one of resilience. After losing both legs in a 2017 Formula 4 racing accident, Billy returned to motorsport and continued to inspire millions through his strength and determination. Now, through the IRONMAN, he aims to inspire again by showing that no obstacle is too great, especially when the goal is to help others.
