The ninth annual CT Challenge Bike Ride will be Friday, July 26, and Saturday, July 27, as the event expands to a rider-optional two-day ride.

The ride, starting and ending at Westport's Fairfield County Club, is the largest annual fundraiser for the CT Challenge, a Fairfield nonprofit whose mission is "to help cancer survivors live healthier, happier, and longer lives," according to a news release.

Participants may choose to ride distances from 10, 25, 50, 75 and 100 miles in one day or up to 184 miles over two days. Each rider has a minimum amount of funds to raise, depending on the ride distance chosen.
