A 5.3k route through Beeston and Holbeck that is not for those who suffer from vertigo. The route takes you over the railway and M621 twice on footbridges, just don’t look down.
Not a bridge too far?.. A day trip up to Ilkley to conquer the second set of three bridges is in order: http://runleeds.co.uk/running-route/ilkley-three-bridges/
