Brilliant! Spectacular setting, friendly atmosphere, and everything very smoothly run. Marshalling was excellent as was commentating. The car park was grassy with space for vans to arrive the night before and just beautiful. Canβt fault the event - just wish I hadnβt left it so long to try a tri again! Iβll be back. Anna C
