Bertie is continuously alluding to his race with Thomas and how he could win next time. He actually raced Thomas again in the seventh season episode Three Cheers for Thomas, but only won because Thomas was sidetracked with collecting the sport medals.
Bertie and Thomas have seemed to continue this tradition of racing. However, in the seventeenth season, he was re-routed giving him an advantage. Thomas is still able to beat him occasionally.
