They started with a swim in the moat around and under the castle. Charlie reckons he did so well overall because of his Roadfox wheels, but I believe his legs also helped! He overtook so many of the previous category that started 15 minutes before him, whilst on the cycle section, and felt he had fresh legs for the final run to the finish.
Overall he was 14th out of 326 finishers. His time was 1hour 27minutes for the 750m/ 26k/ 5k.
