“The Summer Walk was a great experience and so well organised, mapping our route so accurately through central London and we didn’t make a wrong turn once. There were timely pit stops and the food offering was great. I’d definitely be interested in doing something else through Ultra Challenge.”
– Jodie, #TeamAcorns walker
