If your caller from one of six top law firms sounds a little breathless today or tomorrow, it may be because they are racing to Paris on two wheels.

Staff at Ashurst, Baker & McKenzie, Charles Russell, Eversheds, Ince & Co and Simmons & Simmons have just two days to cover the 500km from London to Paris. Without leaving the office, and, we trust, without chemical stimulation apart from the odd flat white. The race, in aid of Breast Cancer Care, takes place on office-based exercise bikes supplied by the charity.

Prizes include the title of 'Fastest Firm' and the much-contested jersey of the fastest partner.

Keep up with the firms’ progress by tracking the leadership board and fundraising updates.
