Although many children come to all of our events to cheer on the efforts of their parents, we do have some races at which we welcome younger participants. Your children will have a fantastic racing experience with aat events. So far this year, we’ve welcomed 500 children at the Surrey Half Marathon Kids Challenge, and sold out of our inaugural Kids Aquathlon places in advance of race day. So please book soon if your children are keen to get involved! Our races are a great way of encouraging kids to participate in physical activity, make new friends and enjoy themselves in the great outdoors.

Julie: “I will book the kids in (to the Surrey Half Kids’ Race) now. They loved the 4 Minute Mile and my son loved the Hard As Snails, he’s joined an athletic club now.” The aat team are very proud of Julie’s kids!
