The 2026 London Marathon is set to take place this weekend, and registration for 2027 is already open. The biggest headline for next year's London Marathon is the 100,000-runner field and the two-day format — a livelier runners' festival week. When registering you can already choose to race on April 25, 2027 or April 26, 2027! The 2026 London Marathon ballot had 1,133,813 people enter, setting a world record. With next year's field set to double, how many will enter the ballot? Did you take part this year? How about next year? Thinking of entering the ballot?
