These are the most popular running and biking routes in southwestern Connecticut

Runners and cyclists in southwestern Connecticut have some favorite trails and tracks for outdoor training.

Strava, a social network for athletes around the world, compiled GPS data from local users to come up with the five most popular running and biking routes in the area. 

The area of Long Hill in Trumbull was the most popular among athletes both running and cycling, according to the site.

Users who sign up with Strava can track their workouts and vital statistics, share with friends on their own personal feed, and join clubs to compete or stay motivated.

Many cyclists across the state ride and train as part of a club. 

More than 1,000 local cyclists are members of the Sound Cyclists Bicycle Club, based in Darien. Aside from offering daily rides and other activities, the club said it hosts an annual ride that attracts riders from across the country called the Bloomin’ Metric.

“2,500 riders enjoy a scenic tour along the Connecticut coast and back roads up to nearly Newtown,” said Yvonne Beecher, communications director of Sound Cyclists Bicycle Club. 

The main goal of most cycling clubs is to simply create a sense of community.

"It provides people a means of competition, having fun, and socializing," said Jacqui Dowd, president of the Ridgefield Bicycle Sport Club

The Ridgefield Bicycle Sport Club said people join for a variety of reasons, from training for triathlons to riding for exercise. The club, like many others,  allows cyclists to share in the experience together rather than ride solo. 

"You can take care of each other," said Dowd. "If something goes wrong on the roads, if you get a flat tire or if something is wrong with your bike, you have people around you that can support you."

And if you are wondering, members of this club ride in all four seasons. 

"As long as roads are safe, we'll get people out there all year long," she said. 

Local runners can also join a club for their sport. Area groups include the Greenwich Track Club, Milford Road Runners, and Pequot Runners.
