Questions
How long is a judo match?
Four minutes for seniors under IJF rules, plus golden score if the contest is level at the end.
Can the timer do golden score?
Not as an untimed round. Set a long round and stop it by hand, or start a fresh round when golden score begins.
How long should randori rounds be?
Four to five minutes is usual, matching contest length.
