This weekend, 4,000 people from all 50 states, and more than 20 countries gathered to ride or walk at one of the largest commemorative advocacy rides in U.S. history.

“Ride for Magnus: Ride for Your Life” calls for immediate action to prevent cyclist and pedestrian deaths nationwide. Organized by The White Line, the ride is dedicated to 17-year-old cyclist Magnus White, a member of the US National Cycling Team who was killed by a driver on July 29, 2023, in Boulder, just days before competing in the Mountain Bike Cross-Country World Championships in Scotland. One of America’s most promising young cyclists, Magnus was also the US Junior Cyclocross National Champion.

His life was cut short when he was struck by a car while biking along the Diagonal Highway in Boulder. His parents, Jill and Michael White, formed The White Line in December 2023, to inspire cyclists around the world and pay tribute to lives taken too soon. The organization is dedicated to advocating for the safety of all vulnerable road users and aims to be a voice for creating safer road environments.

“Nothing we will ever do will bring our Magnus back, because the system we have right now failed him,” Michael White said. “If Magnus was just one quarter of a second faster or slower, he would be here, and none of this would be happening.” After an emotional send-off Sunday morning, cyclists departed from Farrand Field on the CU Boulder campus.

Bikers followed a 13.5-mile route that led them along Fol.
