Latest News About London Marathon 2026

Here’s the latest on the London Marathon 2026.

• Event plan and timing

  • The 46th TCS London Marathon took place on Sunday, April 26, 2026, in London, with the usual elite and mass-participation format. This aligns with the traditional spring timing for the race in London.[2][3]

• Expansion discussions

  • In 2026-2027 reporting, organisers publicly explored the possibility of expanding to a two-day event to allow more participants, potentially up to 100,000 runners, and to raise more funds for charity; no formal approval had been granted as of early 2027 coverage. These plans were described as exploratory and contingent on approvals and coordination among partners.[1][2]

• Attendance and applications

  • The London Marathon continued to attract a record number of applications; for 2026, ballot entries reached about 1.1 million, setting a world-record level of demand and underscoring London’s status as the world’s most popular marathon. In 2026, the event also set records for finishers prior to discussions of any expansion, with a substantial charitable fundraising impact in prior years.[3][7]

• Related events and additions

  • Around 2026, organizers introduced related events and new pre-race activities, including a Friday night 5K event in London as a lead-up to the marathon weekend, intended to broaden participation and engagement in the broader festival of running surrounding the main race.[2]
