UCI tightens bra‑padding checks before Tour de France Femmes time trial
The Union Cycliste Internationale (UCI) announced that it will carry out special clothing inspections ahead of the fourth‑stage individual time trial (21 km from Gevrey‑Chambertin to Dijon) of the 2026 Tour de France Femmes. The checks target illegal padded sports bras – termed “chest fairing” – that research by Professor Bert Blocken shows can cut aerodynamic drag by up to 3.6 %, saving roughly 0.78 seconds per kilometre, or about 16 seconds over the whole time trial.
Teams raised concerns that some riders were using such padding and asked that inspections be performed by female officials in private tents. The UCI cited articles 1.3.032 and 1.3.033 of its regulations, which forbid non‑essential items that modify a rider’s morphology. At least one rider was examined by a male UCI official accompanied by a female witness; no sanctions have been reported so far. The stage was won by Swiss rider Marlen Reusser, who claimed the yellow jersey.
The controversy has sparked debate over fairness and gender‑sensitive procedures, with the riders’ union CPA and several team directors commenting on the need for clear protocols.
