Tube Challenge
The Tube Challenge is the competition for the fastest time to travel to all London Underground stations, tracked as a Guinness World Record since 1960. The goal is to visit all the stations on the system, not necessarily all the lines; participants may connect between stations on foot, or by using other forms of public transport.
As of March 2025, the record for fastest completion (272 stations) is held by Robin Otter and Thomas Sheat, who completed the challenge in 17 hours, 46 minutes and 48 seconds on 10 August 2024.
A similar unofficial tube-related challenge is also completed where participants try and ride all 14 London Underground lines as quickly as possible. This challenge was dubbed: "The All Lines challenge".
