2019 Gulf Winds Triathletes’ Annual St. Marks Duathlon

Click for Results!


The St. Marks Duathlon will be held in the quaint waterfront town of St. Marks and the bike portion will carry participants out into beautiful Wakulla County crossing over the St. Marks River and passing by the entrance to the St. Marks Wildlife Refuge. Transition is located within walking distance of the San Marcos de Apalache Historic State Park and the local shops and restaurants of downtown St. Marks.  The race, which was held from 2012 – 2014, has been resurrected and held in 2017 & 2018 by the Gulf Winds Triathletes.  2019 will mark three consecutive years.  We hope this is the best yet!

Be sure to bring your family and friends to cheer on competitors and get a taste of the Real Florida.

We look forward to seeing you on Sunday, 3/24. If you have any questions, please email us at info@gulfwindstri.com.  And you can visit our club website for more info at www.gulfwindstri.com
