Born on Christmas Day, 1948, Frank Wendon's speedway career began when, aged 16, he bough a bike and attended the Rye House training school. A year later, Frank had secured some second half rides at West Ham but, living in Streatham, he opted to join Wimbledon. It was whilst riding for the Dons that Wendon was seriously injured in a track crash, sustaining a broken collar bone and chipped skull. The injuries sidelined him for three years but,with the inception of the Second Division in 1968, Wendon made a comeback at Canterbury.

Wendon was not able to command a regular place in the Crusaders' team, making 17 appearances and achieving an average of 4.3. After one appearance for Canterbury in 1969, Londoner Frank jumped at the opportunity of joining the new Bombers outfit, making his debut in the Rochester side at Ipswich. In his 25 League appearances in 1969, Wendon gave a succession of strong middle-order performances to achieve an average of a shade under 5 points - but his performance against the Young Czechoslovakia touring side at Brooklands will rank as the highlight of his Bombers career, scoring a paid 10 points from 5 rides.

A drop in form after being plagued with equipment problems saw Frank dropped from the team after the match against Crayford at Brooklands in September. Although unable to regain his place in the Bombers line-up, Wendon achieved two race wins in the final open meeting of the season at Brooklands. Wendon made just one appearance for Romford in 1970, in the away fixtrure at Ipswich, after Ian Gills was found to be unfit to ride.
