At the 1988 Olympics in Seoul a new elimination format was introduced for archery events. In the individual event Hallard ranked 7th in the preliminary round to qualify for the next round but was knocked out of the competition following a 21st-place finish in the 1/8 final. For the first time in Olympic competition a team event was also held. Hallard was part of the British team that also included Richard Priestman and Leroy Watson. Ranked eighth after scores from the individual preliminary round were carried over Britain advanced to the semifinal where they improved four places to qualify for the final in fourth place. A final round team score of 968 meant Britain won the bronze medal behind hosts Korea and the United States. This was the first Olympic archery medal won for Britain since the 1908 Games where five medals, including two gold, were won by British archers.
