What people say about our Virtual Races:

“Thanks to Castle Series for getting me motivated. It wasn’t about speed for me this weekend, just getting the miles in and having some fun!” – Diane

“Enjoyed doing my 1st ever duathlon. Trying to stay upright was a bit challenging with the ice. All legs completed outside I rather enjoyed the cold sunny few days.” – Natalie

“Our monkeys have had a real challenge. Tough course so goodbye road bike, hello mountain bike! Primary aim – no broken bones! Big lesson for the kids…it’s the taking part that counts.” – Kelly
