Supertri Chicago Triathlon continues to drive meaningful value for both participants and the city, welcoming nearly half its field from beyond city limits and creating a significant tourism boost.
Michael D’Hulst, CEO of Supertri, said: “Chicago continues to set the benchmark for what a triathlon can be – inclusive, inspiring, and impactful. The record-breaking registration for 2026 and the incredible satisfaction rates from our athletes show the unique energy of this event. It’s not just about racing; it’s about community, inspiration, and delivering a world-class experience for participants and spectators alike. We’re already excited to see what the 2026 event has in store.”
Supertri Chicago Triathlon has grown to become a fixture on the global triathlon calendar, blending elite racing with one of the world’s most iconic mass participation events. Known for its community-driven approach, the 2025 edition also delivered record fundraising, with thousands racing for charitable causes, including over $90,000 for Lurie Children’s.
With its combination of professional Supertri League racing and the legendary Supertri mass participation event, Chicago is a cornerstone of Supertri’s global mission to “inspire the competitor in everyone.” With its recent acquisition of the New Jersey State Triathlon, Supertri now offers a calendar of landmark mass-participation events in North America to reinforce a true coast-to-coast footprint with Chicago, Long Beach, Austin, Kerrville and Toronto already part of the Supertri family.
