Mondo Duplantis has lost a pole vault competition for the first time in nearly three years, being edged out in his home stadium in Stockholm to Australian Kurtis Marschall.Duplantis, a 16-time world record holder and double Olympic champion, successfully went over 5.80m but did not clear 6.00m in two attempts. He then failed once at 6.05m, raising the height in a bid to win, after Marschall jumped 5.90m with his third and final effort. Windy conditions made things challenging in the Swedish capital.It brings to an end a streak of 40 straight Duplantis wins dating back to July 2023. In that run, the 26-year-old has won an Olympic title, five world championship golds (three indoors, two outdoors), and 18 times in the Diamond League.At this meet last June he set a world record of 6.28m, which he has beaten twice since, most recently this March (now it stands at 6.30m).“I felt a bit unfocused today and I really did not want to lose here in front of my family and fans,” Duplantis said. “But hats off to Kurtis today who beat me fair and square and I have no excuses.”In an exclusive interview with The Athletic at the Tokyo World Championships last September, Duplantis described Stockholm as an “unreliable” pole vault venue. “There’s like a 50 per cent chance that it’s impossible because the weather is just not there and it’s not going to be warm, the wind’s gonna be s***, and it’s not that good a place to jump,” he said.This is a huge scalp for Marschall, who is one of the most consistent jumpers on the circuit — he joined the 6m club last year — and a three-time world championship bronze medallist, including last September (outdoors) and this March (indoors) in finals won by Duplantis.He’ll be eyeing a third straight Commonwealth Games crown this summer, after winning on home soil in 2018 (Gold Coast) and in Birmingham four years ago.There were two outstanding 800m races in Stockholm. Audrey Werro of Switzerland came out on top in the women’s event, running 1:53.98s to beat Great Britain’s Keely Hodgkinson, who placed second in 1:54.33s.It’s a huge win for Werro, whose time is the fastest by any woman for 43 years and set a Diamond League record. It bettered her personal best by nearly two seconds to move up to third on the all-time list. Hodgkinson meanwhile lowered her British record by almost three tenths to 1:54.33s, with that time the fastest by any non-winner ever over two laps.Tactically it looked like Hodgkinson had measured her race to perfection, letting Werro run behind the pacemaker (they split 55.54s at 400m) before overtaking at 500m. Werro, last season’s Diamond League champion, came back hard in the home straight and sprinted to win. It affirms her credentials after losing to Hodgkinson at World indoors in March, with the pair set to face off at this summer’s European Championships, where the Brit will defend her continental crown.Earlier in the meet, 17-year-old Cooper Lutkenhaus won the men’s 800m on his Diamond League debut. The American took down a stacked field, out-kicking former world champion and 2024 Olympic silver medallist Marco Arop.His winning time of 1:42.70s is the second-fastest in 2026, only behind Josh Hoey’s indoor run this January (1:42.50s). Lutkenhaus showed real racing smarts, positioned fourth at the bell as the pacemaker hit halfway in 49.99s. He went through the gears in the final two turns to overtake Arop and win by four-tenths.“He showed how strong he is today. He is going to be a special talent,” the Canadian said of Lutkenhaus.The teenager, who only graduated high school last month, is showing incredible promise. In March he became the youngest-ever world indoor medallist when he won 800m gold in Torun, Poland.This summer he will be looking to revise his world under-20 record of 1:42.27s from U.S. nationals last August. “To come away with the victory with athletes like that in the race, I am really happy,” he said. “The race went exactly to plan, I put myself in a good position with 200m to go having slowly moved up in the field.”Double world champion Melissa Jefferson-Wooden won the women’s 100m in 10.84s, with this her first outing over the distance since winning triple sprint gold (100m, 200m and 4x100m) at the 2025 world championships.It’s her fastest 100m season opener, run with a marginal tailwind (+0.8m/s), backing up her 200m second place to Julian Alfred in Rome last week.“I’d lke to run a PB this summer but I’m not focusing on it — the sky is the limit, though,” Jefferson-Wooden said. She started quickest, leading by nearly one tenth at 60m, and held her form to beat Great Britain’s Amy Hunt, who finished second in a personal best of 10.97s, finally breaking the 11-second barrier.
