At 1,912 metres and known as the "Giant of Provence" this is a tough climb with gradients of up to 11%.
Starting in the village of Bedoin the assent is approximately 15 miles and took John about two and a half hours.
Mont Ventoux is a tough climb and in the 1967 edition of the Tour De France, the English professional cyclist Tommy Simpson died just a kilometre from the summit.
John said "It was a tough climb but a fantastic sense of achievement once I got to the top".
