Canada's high jumping medal contender Derek Drouin is on to the finals.

• Usain Bolt wins 100m gold, Andre De Grasse gets bronze
• Wayde van Niekerk smashes Michael Johnson's 400m world record to win gold
• Brotherhood: Andre De Grasse has friend, mentor in Usain Bolt
• SCHEDULE: Watch track and field at Rio 2016

The 2015 world champion from Corunna, Ont., cruised through Sunday's qualification round in Rio, nailing all four of his jumps at 2.17 metres, 2.22, 2.26 and 2.29.

Fellow Canadian Mike Mason had a rocky day, missing attempts at 2.17 and 2.26 before making his second try at each height. But the Nanoose Bay, B.C., native did not advance to Tuesday's final, missing all three of his attempts at 2.29.

Kenya's Sumgong wins women's marathon, as intruder invades course

Jemima Jelagat Sumgong became the first Kenyan to win the women's Olympic marathon Sunday after a scary moment near the finish when police intercepted a man who nearly marred the event.

Sumgong completed the course in two hours, 24:04 to give Kenya its first gold medal in Rio.

Kenyan-born Eunice Kirwa, who now runs for Bahrain, was nine seconds behind for silver and world champion Mare Dibaba of Ethiopia took bronze.

With about a kilometre to go to the finish line at the Sambodromo parade grounds, a man with a sign jumped over barriers along the route ahead of Sumgong and the other runners, and two police officers on bikes immediately cut him off. The protester then jumped over fencing on the left side of the road, and Sumgong and the other runners continued unhindered.

"I was scared," Sumgong said initially. "I thinking he could maybe ... he could grab one of my colleagues."

When Sumgong ran the London Marathon in April, a man tried to intercept her there. But the outcome was the same: Victory for the 31-year-old Kenyan.

"I was never worried that I'd lose this," Sumgong said. "At 40 kilometres, I knew the gold was mine. At 35 kilometres, I noticed that my other two teammates had dropped off, and that gave me the motivation to carry on.

Sumgong is only the third Kenyan woman to become an Olympic champion, following wins on the track at the 2008 Beijing Games for Pamela Jelimo (800m) and Nancy Jebet Langat (1,500m).

"It was just amazing out there, people cheering for Canada and other Canadians that came out on the course," Marchant said.

"I'm thrilled. There's nothing that beats this."

"I was with the Great Britain girls for a bit and then they were a little bit ahead of me so I kept my eyes on them. My goal was just to start picking people off and to not be passed by anyone," DuChene added.

"So I'm pleased. You know what? I had such a fun time at the end there. I think had the best finish just taking it all in with the crowds and just being so grateful for everything."

Only two of the Estonian triplets in the marathon completed the race. Lily Luik was the fastest of the 30-year-old sisters, clocking 2:48:29 seconds to finish in 97th place.

Leila Luik ended up in 114th place in 2:54:38. But Liina Luik didn't finish, withdrawing before the 35-kilometre mark.

One of the favorites left the race prematurely. Tigist Tufa, the 2015 London Marathon champion, pulled up after 18 kilometres.

Colombia's Ibarguen wins triple jump gold

The Winnipeg runner, who won silver in the event at the Pan Am Games in Toronto last year, started strong and led for most of the race, but couldn't keep up the pace once the reigning world champion Genzebe Dibaba made her move to the outside, drawing the eventual leaders with her.

"What can I say? I knew I had to finish fifth. I was in eighth in the home stretch and one girl stopped before the line and I got seventh," Sifuentes told CBC's Scott Russell post-race.

"So I knew when I finished, there was hope. But I had no idea what the first heat did."

Unfortunately for Sifuentes, her time 4:08.53 wasn't enough to crack the final. But she said just being at the Olympics was a blessing.

"This is hard, but I'm thankful that I was here and I gave it my best," she said.
