The event raises money for cancer research, and 100 percent of proceeds go directly to work being done at Siteman Cancer Center and St. Louis Children's Hospital.
By race day, Pedal the Cause had raised more than $1.6 million. Organizers expect that amount to reach $2 million this year. You can still donate through Pedal the Cause's website.
