Gildan Underwear Run
Take it off. It's for a good cause.
Gildan Underwear Run
It's just like spandex, right?
Gildan Underwear Run
Undies mandatory. Costumes optional.

There’s no better way to cope with pre-race stress than stripping down to your skivvies. In public. At the lakefront. On a Friday. Join us for a unique kickoff to an incredible weekend:

The Inaugural Gildan Underwear Run
Friday, August 25, 2017
Chicago Lakefront
Event Start: 6:30 p.m.

The Gildan Underwear Run is a fixture to our sister race, the New York City Triathlon, and a new addition to the 2017 Transamerica Chicago Triathlon weekend. This 1-mile fun run will be hosted at the lakefront on the Friday of race weekend (full schedule forthcoming). No transitions, no timing chips, no expensive race gear – just 500 strangers running around in their underwear. Perhaps it’s time to start that core routine?

Priority registration will open to current Chicago Triathlon registrants via email link on Thursday, June 1 at 12:00 p.m. CDT. If space remains, a link will be posted for the public via social media at 1:00 p.m. that same day.

A $10 donation is required to register, with 100% of proceeds to benefit the incredible work of the 100 Club of Chicago. Registration is limited to the first 500 registrants. All participants will receive Gildan underwear-themed swag. Complimentary photos and a costume contest with awards will be hosted on-site. Refreshments, gear check, portos and more will be provided.

Stay tuned. It’s about to get drafty in here!
