Once payment is processed, the other teammates will receive an email containing a link which they must follow in order to input their own personal details. At this point, any team members who are not BTF members will be asked to pay an additional £6 for their own BTF day licence.

  • On the bike you must complete a minimum of 10 laps between changeovers.
