Two Runners Shatter Marathon's Two-Hour Barrier in Historic London Race
Finn's Take· TL;DR- Sabastian Sawe became first athlete to legally break two-hour marathon barrier, winning London race in 1:59:30, shattering previous record by 65 seconds.
- Second-place finisher Yomif Kejelcha also broke two hours in 1:59:41, marking historic first time two runners achieved sub-two-hour marathons in single race.
- Revolutionary adidas Adizero Adios Pro Evo 3 supershoe, weighing under 100 grams, played key role with advanced foam and carbon technology improving running efficiency.
Breaking the Unbreakable
The streets of London witnessed history on Sunday as Sabastian Sawe became the first athlete to run a legal sub-two-hour marathon, winning the World Athletics Platinum Label road race in a world record of 1:59:30 . But he wasn't alone in this unprecedented achievement. Yomif Kejelcha finished second in 1:59:41 – the second-fastest time in history and the fastest marathon debut ever .
Sawe crossed the line taking 65 seconds off the previous world record set by the late Kelvin Kiptum in Chicago in 2023 and becoming the first athlete to run a legal sub-two-hour marathon, surpassing Eliud Kipchoge's 1:59:41 exhibition performance from 2019 . The magnitude of this breakthrough becomes clear when you consider that Sawe smashed the men's world record by 65 seconds – a margin virtually unheard of in elite marathon racing.
Kejelcha followed in an Ethiopian record of 1:59:41, the second-fastest performance in history and the quickest ever marathon debut, while Kiplimo secured third place in a Ugandan record of 2:00:28, also inside the previous world record . For the first time in marathon history, three men finished a single race under what was previously the world record.
The Technology Revolution
Both record-breakers wore the revolutionary adidas Adizero Adios Pro Evo 3 , a shoe that had gone on sale just two days earlier . The Adizero Adios Pro Evo 3 is adidas' lightest and fastest racing shoe ever — the world's first sub-100-gram supershoe, averaging 97 grams .
The breakthrough lies in its innovative design. It packs ENERGYRIM carbon technology, next-generation Lightstrike Pro Evo foam, and a kitesurfing sail-inspired upper into a shoe that elite athletes now trust to break world records . The new Lightstrike Pro Evo foam cuts nearly 50% of the weight from previous foam versions while maintaining a 39mm stack. Runners gain 1.6% better running economy and 11% greater forefoot energy return over the Evo 2 .
To put the shoe's weight in perspective, a shoe weighing less than a banana just broke the marathon world record . The technology represents a fundamental shift from traditional carbon plate designs, with Carbon-infused ENERGYRIM as a full-length, U-shaped, perimeter stiffening element, eliminating the need for rods or a broad plate. Unlike other carbon-plated running shoes, this allows a full stack of pure foam underfoot and helps deliver a 1.6% improvement in running efficiency .
The Race That Changed Everything
The lead group moved through the early miles at a controlled but ambitious pace, hitting 5km in 14:14 (2:00:03 pace). They remained together through 10km (28:34) and 15km (43:10), before reaching halfway in 1:00:29 . Sawe ran the second half of the marathon in 59 minutes and 1 second, pulling clear with Kejelcha after 30 kilometers and then making his solo break in the final two kilometers .
The winning time represents an almost incomprehensible pace. Sawe covered the last split (40km to 42.195km) at an average of 4:17 per mile pace (1:52 marathon pace) . For context, most recreational runners would struggle to maintain this pace for a single mile, yet Sawe sustained it for the final stretch of a 26.2-mile race.
Sawe was a late starter as a professional runner. He never competed at a global championship on the track, started racing internationally on the roads at age 26 in 2022, then won the 2023 World title in the half marathon before moving up to the full distance . His coach believes Sabastian has not reached his peak yet .
Redefining Human Potential
The implications extend far beyond elite athletics. Eliud Kipchoge praised the achievement, posting that it was proof "that we are just at the beginning of what is possible when talent, progress and an unwavering belief in the human potential come together" . Kenya's President William Ruto said Sawe had "redrawn the limits of human endurance," calling the triumph "a defining moment" that "reaffirms Kenya as an enduring force at the pinnacle of distance running" .
For everyday runners, the technology trickles down in meaningful ways. The carbon element delivers most of its benefit at elite pace
