Overview
- The 10th Ironman 70.3 Weymouth, which ran on Sunday, Sept. 20, 2026, attracted more than 2,800 competitors and thousands of spectators along the seafront and harbour.
- Harry Lamb won the men's race in 4:13:03 and Katherine Amps won the women's race in 4:49:10, and both praised the crowd support on course and at the red‑carpet finish.
- Competitors completed a one‑lap 1.2‑mile sea swim, a 56‑mile bike loop through Dorset to King's Stag, and a new 2.5‑lap, 13.1‑mile run route in calm, sunny conditions.
- Organisers held the first Ironkids races for children aged three to 15 and families said the addition helped create a festival atmosphere across the weekend.
- Officials said the event delivered a weekend boost for hotels, restaurants and shops, and the early announcement of the 2027 date and registration aims to sustain tourism and athlete interest next year.
