London Marathon 2026 Preview: Course, Weather, Predictions, Hot Takes & Two-Day Race 2027 Rumors

The complete London Marathon 2026 preview from the Marathon Handbook podcast. Michael Doyle, Alex Cyr and Katelyn Tocci break down everything you need to know before Sunday's race: the course, the elites, the weather, the Adidas Pro Evo 3 launch, the 2026 New Balance London kit, the rumored "Double London" two-day weekend for 2027, and plenty of hot takes.

Will Sebastian Sawe break the 2-hour barrier? Can Hellen Obiri surprise on a flat course? Will Tigst Assefa take down Paula Radcliffe's 2:15:25 course record? Will London become the first marathon ever to crest 60,000 finishers? The crew answers all of it, and maps out the fairest way for London Marathon Events to expand to a two-day race without diluting the prestige.

We also preview our on-the-ground coverage: the shakeout run in Hyde Park, our live watch-along at Knees Up in Hackney, the expo at the Running Show, elite athlete press conferences, and the Instant Reaction podcast that drops right after the race.
