They've also got some pretty inspirational runners. Peter is running since his son James was born prematurely at 31 weeks and was rushed into intensive care where he stayed for 8 weeks. James spent the first six months of his life linked up to an oxygen machine at home.
Chloe is supporting WellChild's research into her daughter Lucy's rare chromosome disorder in the hope that other families will get the answers doctors haven't yet been able to give her.
Christine and David are running because their daugter Hannah overcame a potentially fatal illness that was luckily diagnosed early enough.
There are many other amazing WellChild supporters running this year so have a look at the Team WellChild blog to learn more. Good luck next weekend guys.
