The easy answer is one, as in the Decathlon is a single event worth a single gold medal.
The more complex answer is also one. The Decathlon is comprised of ten events with all decathletes competing in all of them for points. Out of the decathletes in the 1976 competition Jenner only won one event, the Discus.
He was 8th in the 100 and Long Jump,
7th in the 110 hurdles,
4th in the Javelin and
2nd in the Shot Put, High Jump, 400, Pole Vault and 1500
