Trailnet is marking the return to in-person events with the Bridge Birthday Bash, a bike ride celebrating the 92nd birthday of the Old Chain of Rocks Bridge and Trailnet’s work making the bridge a walking and biking connection. The ride starts at 9 a.m. on Sunday, June 13 at the Old Chain of Rocks Bridge in St. Louis.

With routes spanning 18 to 80 miles on Madison County Trails, greenways, and quiet roads, the Bridge Birthday Bash is a great opportunity for anyone to enjoy a fun, unique day on their bike.

This ride is the first of the 2021 Trailnet Classics, a series of multi-distanced, supported bike rides across the region that help fund Trailnet’s work to improve walking, biking, and transit in the community.

The Bridge Birthday Bash and all of the Trailnet Classics include rest stops with food and water, marked routes, turn-by-turn directions, and support vehicles to help riders in case of mechanical or first aid issues.

“No matter your experience or comfort level on the bike, we’ve crafted each Trailnet Classic with all skill and fitness levels in mind. All our riders need is a bike, helmet, and a thirst for fun. We’ll handle the rest,” said Matt Hartman, Trailnet’s rides manager.

“After a year that put a pause on in-person events but saw an enormous expansion of people getting into biking, we’re excited to safely bring people together. Everyone who joins our rides is helping make biking and walking better and safer in our community,” said Cindy Mense, Trailnet’s CEO.

Trailnet is following local health rules for organizing events. As rules change, Trailnet staff will communicate details and expectations with riders.

Registration is available now at and is $35 for the public or $20 for Trailnet members. The event is open to the public and members of the press.

Birthday cake celebrating the Chain of Rocks Bridge will be provided after the ride courtesy of The Cup in Edwardsville.
