Canadian trio reaches semifinals in women's 100m hurdles: roundup

Three Canadians advanced to the semifinals of the women's 100m hurdles at the London Olympics on Monday.

Jessica Zelinka of London, Ont., came second in her heat with a time of 12.75 seconds to earn her spot in the next round, trailing Alina Talay from Belarus (12.71) in the race.

"I woke up a little sore," Zelink said. "I didn't train yesterday, took the day off after the heptathlon so today this was my warm up to find my legs."

Zelinka is looking to rebound from a seventh-place finish in the heptathlon over the weekend. She was looking for a top-three finish in her heat and did just that.

"I was like, hey body you’re not done yet," she said. "I followed the same routine and rhythm but I knew the time would be a little slower."

Phylicia George of Markham, Ont., and Nikkita Holder of Pickering, Ont., also qualified for the next round.

"I left a lot on the track, got the rust off though, I hadn't raced in awhile," said George. "I can go a lot faster; it's going to take 12.6 seconds to make the final, then a personal best to step on the podium."

George was second in her heat with a time of 12.83, while Holder advanced with a qualifying time of 12.93.

“It wasn't my best race or start," Holder said. "I'll get through on time and fine tune some things for the semi final."

Geoff Harris of Halifax advanced to the semifinals in the men’s 800 metres.

Harris felt comfortable in the race and says he has more left in the tank.

"There's definitely more there. I've got another gear for sure," he said. "Speed wise I can run with best. I was patient, I knew they would come up on me, got boxed in a bit but I didn't panic and just ran my race, that was the key."

Sudan's Abubaker Kaki had the top qualifying time of 1:45.51.

The semifinal race takes place on Tuesday.
