Coucil-for-Responsible-SportThe 2018 Chicago Triathlon is committed to being environmentally and socially sustainable. In 2012, the race earned certification as a sustainable race by the Council for Responsible Sport and was recognized as a green event by the Chicago Park District. This year we are applying for recertification.

Initiatives include:

  • Recycling and composting in transition, at the swim start, on the course and at the finish festival
  • Sourcing local food and beverages
  • Minimizing our carbon and water footprints
  • Donating unused food to charity
  • Reusing signage and other materials
  • Recycling race bibs and swim caps

We encourage participants to help by:

  • Carpooling or using public transportation to get to and from the race
  • Using your own hydration system on the run to minimize paper cup waste and conserve water
  • Using the recycling, compost and landfill bins provided
  • Supporting our charities

The race is committed to respecting and including athletes and volunteers of all ability, and not discrimination on the basis of age, sexual orientation, socio-economic status, race or religion. If you have comments or suggestions for how we can strengthen our commitment to sustainability and equity, please email us.
