Multiple riders were left with serious injuries after a scary crash with a pedestrian at the Tour of Turkey. 

Video of the incident emerged on Twitter showing a man walking on the side of the road seemingly unaware of the approaching cyclists before causing a major collision. 

The pedestrian, who had his back to the peloton, failed to hear warnings from spectators of the incoming cyclists. 

One nearby fan even attempted to pull the man out of the way at the last-second, but multiple riders crashed into both individuals. 

French Arkéa-Samsic rider Nacer Bouhanni suffered a fractured vertebra in the crash and was taken to a nearby hospital, while Manuel Peñalver of Burgos-BH broke his elbow and required surgery. 

Mirco Maestri (Eolo-Kometa), whose collision with the pedestrian started the pile up, posted a photo of himself on social media sporting bruises and road rash following the crash. 

"Sometimes you just have to get up and push harder than ever ... thinking it doesn't hurt," he wrote alongside the photo. 

Fans reacted in shock on social media, with some labelling the crash "horrifying" and "insane", while others criticised the clueless pedestrian. 

One even suggested "somebody could have died".
