Making a move towards gender parity

Women’s cycling provides an incredible spectacle to sports fans up and down the country. This year, we’ve increased the prize fund, so that for the first time ever, stage by stage, jersey by jersey, the Women’s Tour riders stand to win exactly the same as the men in the Tour of Britain. We hope this proves to be a meaningful step towards gender parity in cycling, and one that ripples out to other sports as well.
