When the clock turned the page
London is already one of the fastest major-marathon courses on the calendar. In 2026, the lead pack did not nibble at the two-hour mark — it walked through the door. Sawe and Kejelcha both finished under 2:00:00, something no one had done in a fully scored road marathon at this level. Behind them, the depth remained brutal: the men's top ten alone stayed packed inside times that, a decade ago, would have been era-defining on their own.
Up front, the race told two stories at once: a generational team performance for Adidas, and a single-model sweep of the biggest results that the supershoe era has ever seen in one mass-participation major. That is rare air — and it matters because it ties a technical bet directly to a day that will be replayed in highlight reels for years.
Not the INEOS 1:59 number — a different line in the book
Eliud Kipchoge's 1:59:40 in the 2019 INEOS 1:59 Challenge is still a cultural landmark. It was also a closed-course, pace-assisted, non-standard format — built to prove a human could cover 26.2 under two hours, not to slot into the same record tables as a city marathon with open racing rules.
What Sawe did in London, as reported, sits in the same book as Kiptum, Kipchoge, and the rest of the world-record lineage: a World Athletics–eligible build of road marathon under major-marathon conditions. The shoe does not "replace" 2019 — it extends the story into sanctioned racing. That is why Sunday mattered to governing bodies, brands, and fans in three different time zones, not just the finishing straight on The Mall.
Why the Adios Pro Evo 3 is more than a lighter update
Most annual supershoe launches shave grams or tweak plate stiffness. The Pro Evo 3, as described by Adidas in pre-race materials cited by the running press, aims at a weight class that barely overlaps with typical elite racers: a claimed ~97g (about 3.4 oz) in a common men's race size, with stack heights at the 39mm heel / 36mm forefoot band that stay inside World Athletics road rules. That is not "trimming laces" — it is a ground-up reallocation of what carbon is for in the system.
ENERGYRIM: carbon at the edge, not under the full foot
Instead of a full-length plate channeling a spring-like lever through the metatarsals, the ENERGYRIM is a perimeter frame: carbon hugging the outer edge of the midsole, leaving the center of the forefoot to behave more like a deep column of Lightstrike Pro Evo foam. The engineering pitch is simple to say and hard to do: stability where the rim is, compliance where the foot loads most — and less mass than a solid plate that has to run the length of the shoe.
Foam, upper, and grip
Adidas is also marketing a new generation of Lightstrike for this line — the "Evo" step — focused on lower foam density per mile of cushion for a given return target. The upper is pared to what elite marathon racing tolerates: light mesh, little spare structure, race-day priorities only. The outsole leans on forefoot rubber in reporting on the build — a nod to the fact that prior Evo generations caught criticism for how they behaved in wet, turning miles.

What this week means for shoes going forward
1. A new weight floor for the podium. When the winning shoes in both headline races are coming in near 100g in race sizes, the rest of the industry no longer gets to treat "light" as a 180g shoe with a new paint job. It forces R&D programs to ask whether grams should move out of the midsole, the upper, or the "must-have" full plate first.
2. Perimeter carbon is now a public blueprint. Brands that have been locked in plate + foam + pod architectures will reverse-engineer the rim idea in wind tunnels, fatigue labs, and on the track. You should expect a wave of edge-stiffness concepts that try to get most of a plate's effect with less of its mass.
3. Regulation and ethics get louder, not quieter. When times move this fast, World Athletics and national federations face the same questions as after previous jumps: Are stack rules enough? Is there a need for energy-storage limits, not just height caps? The shoe cannot answer those — but the result sheet will be Exhibit A in every meeting for the next 18 months.
4. Two product worlds, one sport. A $500, barely-there elite instrument will not replace the volume sellers that most runners will actually buy. It will, however, re-price what "flagship" means in marketing — the same way concepts cars pull families toward smaller tech wins (foam, rubber, geometry) on mainstream trainers.
What this does (and does not) mean for you
A historic weekend for one shoe line is not a instruction to order the most aggressive build on the page. The Pro Evo 3 is aimed at athletes whose mechanics, loading patterns, and racing schedules can use a minimal upper and a narrow, soft heel without paying in missed training weeks. If you are a heavy heel striker or you need torsional help from a shoe, the sensible play is to stay with platforms built for that — our heel-striker guide is a better map than a podium photo.
