John Rees rode a winner during his first season as a National Hunt jockey but did not add to his total despite continuing for four more years.
His first ride was at Market Rasen on November 29, 1974, when Jane Again was seventh of nine finishers in the White Swan Selling Hurdle. His sole victory came at Hereford on Whit Monday, May 26, 1975, when Cherry God beat Abellaro, the mount of Gerald Dartnall, by a head in the Donnington Novices’ Handicap Hurdle. John had three more rides on Cherry God, finishing third once.
He rode for the final time at Huntingdon on Boxing Day 1978, when Chavey Down finished seventh of 17 starters, having led for part of the race, in the St Ivo Novices’ Hurdle (Division 1).
