At least six people, including the driver, were injured in Fort Collins, Colorado, after a truck left the road and struck pedestrians on a sidewalk near the annual Tour de Fat costumed bicycle festival. The collision occurred as tens of thousands of cyclists and pedestrians gathered in the area for the event, raising immediate safety concerns and prompting police to close off the surrounding streets while festivities continued nearby.

The crash happened at around 11.50am on Saturday in the 100 block of West Mountain Avenue in Old Fort Collins, with police arriving roughly 40 minutes later to find six casualties, all of whom were taken to local hospitals with conditions unclear by Saturday evening. It remains unknown whether any festival participants were among those struck, or whether the driver has been arrested or cited, as a Collision Reconstruction and Scene Handling team investigates. The Tour de Fat is a free annual event featuring a costumed bike parade and a brewery party benefiting local cycling charities.
