Fog did not stop the Cohasset Triathlon

Cohasset, MA

The 2026 Cohasset Triathlon was held on Sunday, June 28, 2026 under foggy conditions. The foggy conditions forced the race director to cancel the swim portion of the event, substituting a one mile run.

The Cohasset Triathlon is a leading sprint-distance multisport event that takes place every year in Cohasset, Massachusetts. Renowned as the largest race of its type in the area, it includes a picturesque 0.25-mile ocean swim, a 12 to 14-mile cycling segment, and a 3.2-mile run along the seaside. The event supports local charities such as the Juvenile Diabetes Research Foundation and the Sandy Beach Association.
