Jamaica's relay gold secures Usain Bolt's unprecedented triple-triple. 

Bolt anchored the Jamaican men's relay team to gold — his ninth in total — to complete a never-seen-before record of first place finishes in the 100, 200 and 100-metre relay three Olympics in a row. Japan won the silver in the relay race with Canada earning the bronze after the Americans were disqualified for an exchange violation.

Both walkers got up and finished with Arai slipping across the line just 14-100ths of a second ahead of the Canadian. Athletics Canada appealed and, for a time, Dunfee held the bronze until a counter appeal had the decision reversed. That's silver medallist Jared Tallent of Australia on the ground behind Dunfee.

French race walker Yohann Diniz had an especially rough race. The 50-kilometre world record holder collapsed mid-race with stomach pains but got up and finished.

Show jumper Eric Lamaze won the bronze atop Fine Lady 5 on Friday.

Canada's most decorated Olympic jumper had the fastest time in the six-person jump-off but settled for third after pulling his only rail of the competition.

Lamaze made headlines in Canada but it was British show jumper Nick Skelton (pictured) who stole the show, claiming his first individual gold medal with a commanding performance atop Big Star. The 58-year-old rider, who already has a silver medal from London 2012, teared up on the podium, which he shared with Lamaze and Sweden's Peder Fredricson, who rode clear to take silver.
