While Vasco Vilaça was sprinting clear of a six-man lead pack on the run course in Samarkand on Saturday, Alex Yee was on the streets of London the following day — clocking 2:59-per-kilometre splits through the 28km mark of the most significant marathon in history. The Olympic and world champion made a calculated choice to skip the opening round of the 2026 WTCS season, and the weeks ahead of the LA28 qualification window opening, to serve as a pacemaker in Sabastian Sawe’s sub-two-hour world record run at the TCS London Marathon.
It cost him early qualification points. It cost him nothing he can’t recover. But his rivals aren’t waiting around.
London — Yee’s Role in a Historic Day
Yee hit halfway of Sunday’s 46th London Marathon in exactly 63:15 before peeling off at 28.15km, his pacing duties fulfilled with metronomic precision. What followed was extraordinary. Sawe ran the second half in 59:01 — the fastest negative split ever recorded — finishing in 1:59:30 to become the first man to officially break two hours under race conditions. Yomif Kejelcha crossed in 1:59:41 on his marathon debut. Jacob Kiplimo ran 2:00:28 for third, itself a sub-world-record performance. All three men broke the previous world record of 2:00:35.
Yee’s involvement wasn’t random. It was reciprocity. Emile Cairess had paced the triathlete through 21 miles of the December 2025 Valencia Marathon, helping him to a 2:06:38 finish — second on the UK all-time list at that point. Sunday reshuffled that ranking: Mahamed Mahamed (2:06:14, 10th) and Patrick Dever (2:06:18, 11th) have since moved above Yee into second and third on Britain’s all-time charts.
“Emile is a great runner, and he was a massive help to me at last year’s Valencia Marathon. My hope is that I can repay him for that help by supporting him as much as I can and play some part in helping him achieve his ambitions.” — Alex Yee, pre-race
“‘I was there’ moment today for British and World history — proudly pacing the Brits today.” — Alex Yee, post-race via Instagram
The women’s race had its own piece of history. Tigst Assefa broke the women-only world record with 2:15:41, ahead of Hellen Obiri (2:15:53) and Joyciline Jepkosgei (2:15:55) — the first time three women have broken 2:16 in a single race.
Samarkand — Vilaça Takes the Opener
Back in Uzbekistan, Vilaça was composed throughout. Thirty-degree heat, a fractured race, a six-man lead group on the run — and then a decisive move in the final 400 metres to win the WTCS season opener in 1:43:33, edging Germany’s Henry Graf by four seconds and Canada’s Charles Paquet by eight. Hungary’s Márton Kropkó had led the swim in 17:33, but the run is where it unravelled for the rest. Oliver Conway and Hugo Milner posted the day’s fastest run splits — 29:36 and 29:40 — finishing fifth and seventh respectively for Britain.
Beth Potter won the women’s race with considerably less drama. Her 33:36 run — fastest of the day — overhauled the 34-second T2 advantage Georgia Taylor-Brown had built on the bike, and Potter crossed in 1:53:17. Leonie Periault took second in 1:53:26; Jeanne Lehair of Luxembourg finished third in 1:54:20. Defending WTCS champion Lisa Tertsch had a race to forget, finishing 33rd, over ten minutes down.
The Qualification Picture
Yee wasn’t the only notable absence. Hayden Wilde and Matt Hauser both skipped Samarkand in favour of T100 Singapore — a sign of just how fragmented the men’s elite landscape has become heading into the LA28 cycle. Three podium-capable athletes missing handed Vilaça a clean early points lead. On a qualification timeline opening in May 2026 and running through to May 2028, that kind of start matters.
Yee’s next triathlon start hasn’t been confirmed. He remains the man to beat for Los Angeles. But Vilaça and others are already building their case.
What’s Next
The WTCS circuit moves on to its next scheduled stop, with athletes chasing LA28 qualification keen to bank points early in a two-year window that rewards consistency above all else. For Yee — in triathlon and in marathon — the clock is still very much running.
