Marazion Triathlon

The Marazion Triathlon takes place on 30 May 2026 at Marazion Beach, TR17 0EQ. It is organised by IntoTRI and is set in Mount's Bay with St Michael's Mount as a backdrop.

The race includes a sea swim in the typically calm waters in front of the mount, followed by a Cornish flat bike course through quiet country lanes of west Cornwall. The run is a fast and flat route along the Marazion seafront path where passers-by, spectators and supporters are positioned near the finish.

Race formats cover a range of distances and event types, including:

  • Super Sprint
  • Olympic distance
  • Middle Distance 70.3
  • Middle distance Aquabike
  • 70.3 Relay

Entry prices range from £45 to £137. A middle distance Aquabike option is listed as new for 2026, providing a longer distance race without the running section. Visit the organization's website for the most recent information.
