Yes. Our system is designed to allow users to easily register and create or join teams before the challenge start date.
We recommend your challenge website goes live 2-4 weeks or so before the challenge starts to allow you time to promote it and give people time to register to take part and create and join teams in advance so they can begin to add their distances as soon as the challenge begins.
We are here and happy to advise and help you through the set-up process.
