Switzerland's Marcel Hug and Catherine Debrunner arrive at Sunday's TCS London Marathon carrying the same ambition from opposite ends of the record book. Hug is one victory from equalling David Weir's record eight men's London titles; Debrunner, already the three-time defending champion, missed her own women's world record on this course last year by two stubborn seconds and has said publicly that putting it right is the only reason she is back on Blackheath so soon after Boston. If both Swiss push-rim specialists win on Sunday they will close the 2026 spring majors with five wheelchair victories between them from six starts — an almost ludicrous level of duopoly in a discipline that has never been deeper.
Hug's form is beyond doubt. On Monday he cruised to his ninth Boston Marathon title in 1:16:06, his fourth straight victory on Boylston Street and his eighth podium in the race's history. He has won the last five men's wheelchair crowns in London and seven in total; Sunday's race gives him a chance to become only the second male athlete to lift that trophy eight times. The man he would be joining, David Weir, sits in the BBC broadcast truck these days and has gone on the record calling Hug "the greatest there has ever been on a marathon course". A pushback is likely from Japan's Tomoki Suzuki and the Netherlands' Jetze Plat, who finished second and third in London last year and have both posted faster splits in training over the winter, but nobody in the field has beaten Hug over 26.2 miles since 2023.
Debrunner's task is arithmetically tighter but tactically cleaner. Her current women's world record of 1:34:16 was set on the Boston course in 2024; on the undulating but net-downhill London layout last April she came home in 1:38:22 — two seconds short of the London course record she herself holds. The TfL road surface has been re-asphalted along the Embankment since then, a small detail that Swiss-Paralympic coaches quietly welcome, and the forecast of a dry 12C with a light south-westerly tailwind through the second half of the course is close to ideal. Debrunner has said the 2026 edition is "a chance to fix an accounting error" — a characteristically low-key Swiss line that hides a training block built almost entirely around a sub-1:34 attempt.
The resistance in the women's field is formidable even with Manuela Schär racing with reduced ambition after a shoulder problem through the winter. Tatyana McFadden, London champion four years in a row from 2013 to 2016, has been producing her best track form since Rio, and Australia's Madison de Rozario — the last athlete to beat Debrunner in London, back in 2023 — has altered her race-day push-rim set-up to get on terms in the early miles rather than rely on a late surge. Britain's Eden Rainbow-Cooper, fresh from her second Boston title on Monday, is a genuine podium contender at 24 and has said a sub-1:36 is the goal; her Boston time of 1:30:51 was run on a faster course but suggests she can press Debrunner on any benign day.
Both wheelchair races start at 08:50 British time from the Blue and Green Start in Blackheath, 40 minutes ahead of the elite men and 23 minutes ahead of the elite women. The BBC coverage on BBC One and iPlayer from 08:30 will carry the full race; the winners are expected at The Mall shortly before 10:20. The double prize for Swiss Para-Athletics would mean four London trophies in the cabinet in one morning and, for both athletes, the end of the spring majors campaign with records intact. It would also confirm what Weir said in the Telegraph this week: that the current era of wheelchair marathon racing is the strongest any generation has ever seen, and that two athletes from a country of eight million people are running it.
