Ironman World Championship
The granddaddy of endurance events returns to Kona in 2026 as a reunified single-day race for the first time since 2022. Approximately 3,000 athletes swim 2.4 miles in Kailua Bay, bike 112 miles across the lava fields, and run a marathon along Aliʻi Drive. The town transforms into a carnival of determination.
Tip Book accommodations well in advance — the entire Kona coast fills up. Aliʻi Drive is the best spectating spot for the run.
