Canada's Damian Warner, Pierce LePage sit 1-2 after 3 events in decathlon

Canada's Damian Warner opened his quest for an Olympic decathlon title in emphatic fashion.

The 31-year-old from London, Ont., ran 10.12 seconds in the 100 metres to tie his decathlon world record in the event, then put down a long jump of 8.24 metres, 0.04 off his world decathlon best and a new Olympic record in the sport. The distance would have been enough to win bronze in the event earlier this week.

"I felt like I kind of had a stutter going into that jump, and then I landed and I think I turned to my coach and was just like, 'I think it's over eight metres.' And he's just like, 'Oh, it's 8.24.' I don't know how, but I'll take it," Warner said after the race.

Warner then threw a season-best of 14.80 metres in the shot put, considered one of his weaker events.

"I feel like out of the three events today, that was the one that was the lowest point value. But I think it's the one I'm happiest about. Because all year shot put's been inconsistent for me," he said.

Warner is the No. 1-ranked decathlete in the world this year after shattering his Canadian record at the Hypo-Meeting in Götzis, Austria. His score of 8,995 there was the fourth best in history, and through three events in Tokyo he is on pace to break the record once again.

"It was awesome that I was not only able to jump far, but to repeat the same performance I had earlier this year. I couldn't ask for a better start in this decathlon and I gotta just keep executing and keep competing and hopefully we're getting the result we're looking for," Warner said.

Warner (2,966 points) and fellow Canadian Pierce LePage (2,773) now sit first and second in the overall standings through three events. While Warner won the 100 and long jump, he placed 11th in shot put. LePage, meanwhile, placed top-four in all three events.

LePage ran 10.43 in the 100, the third-fastest time on the morning. Like Warner, LePage won his long jump group with a season-best distance 7.65m. The mark was only bested by Warner across the entire field.

LePage, from Whitby, Ont., then threw a personal best of his own in shot put, winning a group featuring Warner and world-record holder Kevin Mayer of France with a distance of 15.31m.

Warner said he enjoys competing against LePage.

"We get along well, and we have similar strengths in decathlon. He is an awesome guy to have there.

Warner's record-breaking performance in May came after a winter of training in an unheated hockey arena in London. COVID-19 protocols shut down the University of Western Ontario indoor track facility, so his coaches outfitted the arena with a 40-metre track runway, pole vault and high jump pits, and a throwing circle.

The decathletes face gruelling conditions in Tokyo. The temperature at Olympic Stadium at 9 a.m. for the 100 was 33 C, but felt like 47 C with the humidity.

Warner said it's the hottest of three Olympics in which he's competed. He's used cooling technology to battle the stifling heat.

"This [cooling vest] is a life-saver, like a life vest. It is hot out there, and for shot put there was no shade, so this was huge. Having one of these and an umbrella kept us as cool as possible," he said.

The decathlon features 10 events over two days. They still have the shot put, high jump and 400 on Wednesday. Thursday's Day 2 events are the 110-metre hurdles, discus, pole vault, javelin and 1,500.

Canada's Ellenwood in women's heptathlon hunt

Meanwhile, Canada's Georgia Ellenwood is eighth in the heptathlon following two events.

In her Olympic debut, the 25-year-old was 13th in the 100m hurdles with a time of 13.47 seconds and sixth in the high jump at 1.83 metres, a personal-best mark.

Ellenwood, of Langley, B.C., finished 11th at the 2021 Hypo-Meeting, and soon after set a PB of 6,314 points.

The Canadian currently sits at 2,071 in Tokyo, with shot put, 200, long jump, javelin throw and 800 remaining. Competition resumes Wednesday evening in Japan.
