London Marathon 2026: Your Guide to Running, Watching & Key Details

The London Marathon, a cherished event for over 40 years, is set for Sunday, April 26, 2026. This colossal mass participation race typically kicks off with Elite and Wheelchair events from 8:30 am, followed by the main field around 9:30 am. The iconic 26.2-mile route begins in Greenwich and Blackheath, merging participants by mile three before winding through Woolwich, Greenwich town centre (passing the Cutty Sark at mile 6), Rotherhithe, and Bermondsey. A highlight is crossing Tower Bridge at mile 12, marking the halfway point. Runners then navigate a circuit around Canary Wharf (mile 18) and the Isle of Dogs, eventually following the Thames towards Westminster Bridge, culminating in a spectacular finish on The Mall in front of Buckingham Palace (mile 26). Other notable landmarks include the Tower of London, London Eye, and Big Ben.

Watching the marathon offers varied experiences. Prime locations like Greenwich, Tower Bridge, and the finish line area are exceptionally busy, providing an electric atmosphere. For a quieter viewing experience, spectators can head to Rotherhithe, Bermondsey (miles 9-12), or east of Limehouse and Canary Wharf (miles 14-21). Five accessible viewing areas cater to disabled spectators, and the entire event is broadcast live on BBC One, BBC Two, and iPlayer, allowing for easy home viewing.

Participating in the London Marathon offers immense personal achievement and significant fundraising opportunities, with many attempting Guinness World Records in elaborate costumes, such as Captain Underpants or a Felix Project van. However, securing a spot is highly competitive; the 2026 ballot attracted 1.1 million entries for an event that saw 56,000 finishers in 2025. Aspiring runners often pursue coveted charity places, requiring a minimum fundraising commitment. The event also brings temporary disruptions, with extensive road closures starting days before and continuing into Monday, impacting traffic and bus services along the route. Residents are advised to move vehicles by Saturday night to avoid towing.
