London’s sub-two-hour marathon entered a rule-bound record book

On April 26, 2026, Sabastian Sawe won the London Marathon in 1:59:30. Yomif Kejelcha followed in 1:59:41. Both finished below two hours, but the historical distinction depended on more than the clock: World Athletics initially marked the performances as subject to its record-ratification process. ^[1]

Sawe reached halfway in 1:00:29 and covered the second half in 59:01. He separated from Kejelcha about a mile from the finish. The race report distinguishes this competitive performance from Eliud Kipchoge’s earlier exhibition run; an exhibition time and a record-eligible race result are different claims. ^[1]

That eligibility has measurable boundaries. The 2026 rules require an approved course measurer, limit the straight-line separation of start and finish to half the race distance, and restrict net elevation loss to one metre per kilometre. These constraints prevent every fast point-to-point marathon from becoming directly interchangeable in the record book. ^[2]

Tigst Assefa also set a mark in London: 2:15:41, nine seconds faster than her previous women-only marathon record. World Athletics formally ratified both her performance and Sawe’s on July 23. Sawe replaced Kelvin Kiptum’s 2:00:35 from Chicago in October 2023. ^[3]

Assefa’s category matters. The rules maintain separate women’s road records for mixed-gender and women-only races. Separate start times can establish a women-only race when the gap prevents assistance, pacing or interference from the men. Calling her result simply the fastest women’s marathon would erase that distinction. ^[2]

For runners comparing courses and spectators reading a record headline, the useful questions are which category applies and whether ratification followed the initial result. This retrospective reports the federation’s decision; it does not independently certify the course or attribute the times to shoes, training or another untested cause. ^[2]
