We're taking on the Thames Bridges Challenge, walking 25km across all 16 of London's historic bridges, in memory of Ruby Fuller.

Ruby was the daughter of Emma Jones, who is part of the Ashden Cities Team. Ruby was a passionate eco-warrior. She died of blood cancer (lymphoma and leukaemia) aged just 18.

She asked for money to be raised in her memory to find better treatments for blood cancer. Every penny we raise will go directly to supporting research.
