Today is the first day of the Great British Walking Challenge as part of the National Walking Month organised by national charity "Living Streets" -  the month includes Walk to Work week (14–18 May) and Walk to School week (21–25 May).

Living Streets are urging everyone to record their walking miles during the month of May in a challenge to see how many times the nation can collectively walk from John O'Groats to Lands End.

To sign up to the challenge and log your personal miles, calories burned and carbon emissions saved visit the Living Streets website and join the campaign.
