High Barnet bus delay impacts Tube Challenge attempt

Daniel Keeble, 43, completed the London Underground network's Tube Challenge in 19 hours and 17 minutes on 10 October 2026. The challenge requires visiting all 272 active Tube stations using only public transport within a single continuous journey. Keeble began his attempt at Chesham at 5:16 am and concluded at Heathrow Terminal 5 at 12:30 am the following morning. During his journey, Keeble raised £2,500 for Cancer Research UK.

Keeble's attempt was affected by a 40-minute delay at High Barnet station. He arrived to find the connecting bus he needed had departed, causing him to miss his planned connection. This delay meant he had to wait for the next available bus service. The challenge rules permit the use of scheduled public transport between stations but prohibit private means such as taxis or bicycles. Keeble noted that delays involving overground services or buses are the primary risks in such challenges.

Despite the setback, Keeble was able to resume his journey and eventually reach Heathrow. He expressed relief upon seeing the last train to Heathrow was still scheduled to depart with sufficient time, allowing him to complete the challenge. The current world record for the Tube Challenge is 17 hours, 46 minutes, and 48 seconds, set by Robin Otter and Thomas Sheat on 10 August 2024. Keeble stated he is already planning another attempt, potentially incorporating the Elizabeth line.
