The Poudre River Trail has several community events throughout the year to encourage people to experience the trail.

The Poudre River Trail-Athlon

Save the date for our next Poudre Trail-athlon: at the Poudre Learning Center.

The Poudre Trail-athlon is a 'Triathlon with a twist'. Participants take part in as many of the 9 event stations as they like in a self-paced morning of fun. From activities that will get the heart pumping such as the bike ride and fun run, to more relaxed activities like bird watching and chalk art, there is something for everyone!

Participants who complete at least 3 events receive a goodie bag and an event t-shirt! Along with that refreshments, entertainment and some games of chance are available to everyone who comes! Best of all - IT'S FREE!!

The Poudre River Trail Challenge

The Challenge Event has two parts - Pack the Trail and Challenge the Trail: You can participate in one or both, but everyone should get involved in this super fun and hilarious event. Pack the Trail involves beginning at Island Grove Park and traveling out on the trail in any appropriate form of travel. Costumes and unique forms of travel are encouraged! Prizes are awarded! Help us set a record every year for the most number of people on the Trail in one hours' time.

For the more adventurous types, the Challenge the Trail portion provides a fun obstacle course with all sorts of unique challenges along the way. Of course there is a mud pit involved that provides a fun challenge for the runners and an entertaining spectacle for the viewers. Back at Island Grove, entertainment and food are provided for the participants with beverages available for purchase. Each year we will build on the success by having vendors, games, and even more fun! This annual event is held in September to wrap up the Summer season for the trail.
