Athletes start with a sheltered ocean swim at Santos Beach, then tackle a hilly, scenic 90 km ride through the Western Cape’s rolling countryside before a two-and-a-half-loop half marathon along the harbor and up toward Cape St. Blaize lighthouse. The course blends postcard views with honest elevation, ideal for strong all-rounders and first-time 70.3 racers alike. Expect professional timing, lively crowd support, and TriClub rivalries that add extra spark to race day.
