Coucil-for-Responsible-SportThe 2016 Transamerica 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
Supporting local charities

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.
