A group of bicyclists got to pedaling recently as they rode over 100 miles in each direction along the Russian River in Sonoma and Mendocino counties to raise money for San Francisco-based nonprofit Safe & Sound.

Twelve riders began their journey for Safe & Sound’s 11th annual Russian River Ride on Sept. 8 at the nonprofit’s Waller Street location in the city’s Cole Valley neighborhood. A thirteenth cyclist joined the ride on the way back.

The cyclists returned two days later, on a Saturday, having pedaled a total distance of 200 miles and climbed over 7,000 feet. The fundraising campaign has also received over $88,000 in donations as of Thursday for the nonprofit, previously named San Francisco Child Abuse Prevention Center, which has the goal of strengthening families and ending child abuse.

“It was a challenging ride with up to 115-degree temperatures and limited shade on the way out,” said Justin Dombrowski, one of the riders.

The ride back was “much cooler, but had more headwinds to push against,” Dombrowski said.

According to the organization’s website, funds raised through Russian River Ride help support various programs that teach children safety lessons, provide parents with positive skills and techniques for interacting with their children, and bring together lawmakers and community leaders to work together to strengthen San Francisco’s families.
