Sigrid Haugset is a current leader in her field, noted for steering coverage and commentary around the Tour de France Femmes and related aerodynamics scrutiny.
Riders are under scrutiny as padded bras and other non-essential items are checked for aerodynamic efficiency during the stage four time trial. Organisers have issued final checks and will enforce UCI regulations to ensure fair competition.
Haugset has claimed a dramatic solo stage win and the yellow jersey in the Tour Femmes, with two minutes 2 seconds ahead of Kim Le Court ahead of the 21km time trial. The Norwegian champion has become the first from her country to wear yellow in this race.
Marlen Reusser has finished the 21km course in 27:30, taking a 14-second lead over Demi Vollering in the Tour de France Femmes stage four. Reusser now leads the general classification by 14 seconds as the race moves into mid-mountain stages, with Sigrid Haugset dropping from yellow to fourth.
