Career
Hewson was one of the first men to run a four-minute mile, clocking 3:59.8 at the White City Stadium in London on 28 May 1955. As he placed third to László Tábori and Chris Chataway, he became the first to run a mile in less than four minutes and not finish in the top two. Before that race, only Roger Bannister and John Landy had run a four-minute mile.
