What happens in the team car during a cycling race?

A directeur sportif must juggle route navigation, team communication, tactics and technical backup - all while driving at high speed. Amy Sedghi hitches a ride on the women's Tour de Yorkshire to see how it's done

"I need a bike change". The urgent call comes after about 45km.

Another rider has hit Audrey Cordon-Ragot's rear wheel in women's Tour de Yorkshire and the radio crackles with her call for a replacement to be brought forwards. The Wiggle High5 team's directeur sportif, Donna Rae Szalinski, has her foot on the accelerator and a hand on the horn, beeping a warning at the other support cars as she zips up the right hand side at 70kmh to deliver a new bike.
