Pat took part in the Thruxton 500 miles endurance race on a works Ariel Arrow. 

The new 250cc two stroke bike was entered by Ariel  after being prepared by their works team.

Pat and Margo Pearson were planning to ride in the competition. Unfortunately Margo was injured in practice and was replaced for the event by Olga Kevelas shown on the right of the picture.

The machine proved less than reliable, when the engine became worn and the piston came up and closed the spark plug gap.
