Sebastian Sawe just ran 1:59:30 on the streets of London — the first sub-two-hour marathon in history on a sanctioned course. And he wasn't alone. Yomif Kejelcha, in his marathon debut, ran 1:59:41 to make it two sub-2s in a single race. On the women's side, Tigst Assefa lowered her own women's-only world record, with Hellen Obiri running a huge PB just under 2:16 for second.

Michael Doyle, Alex Cyr and Katelyn Tocci recorded this instant reaction from Knees Up on Hackney Road, with Jessy Carveth dialing in live from the finish line media center — including a quick word with Sawe himself before the press conference.

In this episode:

• The moment the media center went silent — and then erupted — as Sawe came around the final bend
• How a 90-second negative split delivered the first official sub-2
• Yomif Kejelcha's astonishing marathon debut and what it means for the next decade of the event
• Tigst Assefa, Hellen Obiri, and the women's race that almost got lost in the sauce
• The Adidas Pro Evo 3: why Adidas held it back from Boston, and what it does to the shoe wars
• Where John Korir's 2:01 in Boston now sits in the conversation
• Athlete vs. shoes vs. nutrition: the Maurten data on Sawe's pre-London block
• Whether the marathon has finally been "figured out" — and what that means for the rest of us
• Boston vs. London as a race weekend, the case for a two-day London in 2027, and why this one race may have just changed the sport

Michael Doyle and Jessy Carveth sit down for their full elite preview of the 2026 London Marathon, breaking down the top five storylines ahead of Sunday's race.

Sebastian Sawe and Jacob Kiplimo headline a men's field that Sawe himself says will require a course record to win: 2:01:25, set by the late Kelvin Kiptum in 2024. Kiplimo arrives fresh off a ratified 57:20 half marathon world record in Lisbon and a World Cross Country title in January. Sawe is expected to debut the Adidas Adios Pro Evo 3, setting up a head-to-head super shoe war against Kiplimo's Nike Alphafly 4.

The women's race took a hit when two major names withdrew, but Tigst Assefa (defending champion and women's-only world record holder) and Helen Obiri make it a showdown worth tuning in for: Obiri finally gets her shot at a flat, fast course after a career built on the hills of Boston, New York, and Paris.

In the men's field behind the big two: three former track stars: Yomif Kejelcha, Hagos Gebrhiwet, and Joshua Cheptegei: try to translate their 5K/10K brilliance into 26.2. Cheptegei is still looking to crack the marathon; Kejelcha and Gebrhiwet are both making their debuts.

The British field takes a hit with Emile Cairess withdrawing injured, leaving Mohamed Mohamed, Phil Sesemann, and Patrick Dever to chase Mo Farah's national record of 2:05:11. On the women's side, Eilish McColgan enters with a healthy buildup and a European 10K record (30:07 in Valencia) to her name.

It's London week. Michael Doyle, Alex Cyr and Katelyn Tocci deliver the Marathon Handbook one-stop preview of the 2026 TCS London Marathon: course, elites, weather, the jacket design, shoes, ballot drama, and the looming question of whether London Marathon Events can pull off a two-day "Double London" in 2027.

What's in this episode:

A brief history of London from the 1981 inaugural race (6,255 finishers) through the 1.3 million applicants now fighting for roughly 60,000 spots. Why the ballot has made London the single hardest World Marathon Major for internationals to enter, and how the charity-bib and running-club routes actually work.

A course walkthrough of one of running's great spectacles — the staggered southeast start, the 9:05 elite women's gun, Cutty Sark at mile six, Tower Bridge at the halfway inflection, Canary Wharf, Big Ben, and the jaw-dropping finish down The Mall past Buckingham Palace into St. James's Park.

Weather check: a probable high-40s to low-60s°F day, sunnier than ideal but dry and low humidity. The crew think we're lined up for a Boston-style "no excuses" day and some serious times.

The 2026 New Balance London kit, a.k.a. the "Cheetah Girl" jacket — the crew rate it, debate whether London should have a defined color system, and land on an official Marathon Handbook freshness score.

The Adidas Pro Evo 3 is expected to formally launch in London, likely on the feet of Sebastian Sawe and Tigst Assefa. The shoe wars angle, why Adidas held it back from Boston, and what a "win on the shoe" does for the brand narrative.

The Double London 2027 rumor: reporting out of the UK suggests London Marathon Events is exploring a two-race weekend. The crew debate every format — men/women split, elite/mass split, same weekend vs two seasons — and Michael lands on an elegant Boston-flavored solution: a qualifying race Saturday for performance runners, the iconic lottery mass race Sunday for everyone else.

Predictions and hot takes:

• Will London break the 60,000-finisher barrier for the first time in history?
• Does Sebastian Sawe go sub-2 on the London course?
• Does Tigst Assefa finally take down Paula Radcliffe's 23-year-old course record of 2:15:25?
• Where does Hellen Obiri land on a flat course she has never run before?
• Which brand wins the day — Adidas, Nike, or a dark horse?
• Plus the updated Marathon Handbook World Marathon Majors Power Rankings as of April 22, 2026.

Coverage plan for the weekend:

The crew will be on the ground Thursday through race day. Shakeout run Saturday at 10 AM in Hyde Park (Serpentine loop) — all welcome. Live watch-along Sunday at Knees Up cafe in Hackney, streaming on the Marathon Handbook YouTube channel as a second-screen companion to the broadcast. Instant Reaction podcast drops the moment the race wraps.
