2026 Optimism Cal Tri Newport Dunes

Held at the calm, protected waters of Newport Dunes, this Cal Tri Events race offers a dozen distance options and is billed as continuing one of the longest-running triathlons from the same location. The sheltered lagoon swim is ideal for beginners and nervous first-time triathletes, while sprint, Olympic, aquabike, and relay formats give experienced racers plenty to choose from. The flat bike and run legs around Back Bay round out an accessible, well-supported day. Register online in advance; arrive early for body marking, transition setup, and wave-start instructions detailed in the athlete guide. It's an excellent introduction to the sport in a friendly setting.
