South Korean world champion, Kim Woo-jin, on Friday set the first world record of the 2016 Olympic Games in Rio with a score of 700 in the 72-arrow ranking round.
The 24-year-old’s score exceeded the mark of 699 set by his countryman, Im Dong-Hyun, at London 2012.
Patrick Huston was the first Briton in competitive action at the Games, finishing 38th out of 64 archers.
The ranking round decides the draw for the Olympic round, in which archers compete in a knockout tournament.
Kim, referring to the men’s team title, which will be decided on Saturday, said: “It’s just the ranking round, so today’s not really big happy.
“Getting the world record is important, but tomorrow’s matches are more important.”
The knockout rounds of the individual competition begin on Monday with the final scheduled to start on August 13.
