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. The current record for fastest completion of the challenge is 15 hours, 45 minutes and 38 seconds that was set on 21 May 2015.

At EAVE our mission is to eliminate the loneliness and isolation that can be caused by hearing loss. We work to educate people working in noise about the associated risks and what they can do to avoid hearing loss. Our ear defenders are smart because they not only protect hearing while doing noisy work but they also collect easy to understand data on actual personal and environmental noise exposure. This data can then be used to reduce and manage risks related to Noise Induced Hearing Loss. 

We will use our technology to map the noise levels on the entire London Underground network on April 3rd while also educating travellers on the underground about the levels of noise they are being exposed to. We'll also be sharing simple tips and tools to help people protect and check their hearing.  

The National Deaf Children Society focusses on three fundamental areas where they can make the biggest difference.

They'll continue fighting to improve the services received by deaf children and young people.

They’ll champion the development of good language and communication skills.

They’ll shine a spotlight on the importance of being independent and the transition into adulthood.
