The 2016 Olympics featured seven participants, led by team captain Antoine Adams. At the event, Collins was the first 40-year-old to run a 100 meters under 10 seconds, where he was the oldest sprinter at the Games. Collins advanced the furthest of any Saint Kitts and Nevis athlete, reaching the semi-finals of the event. He finished sixth in his heat with a time of 10.12 seconds and did not advance to the finals. Adams and Lawrence both reached the quarter-finals in the same event.
