Leeds & Liverpool Canal. Linking the cosmopolitan cities of Liverpool and Leeds, the Leeds & Liverpool Canal is the longest canal in Britain built as a single waterway. Join us for just one or all five days of the event and enjoy the sites from the lovely trail paths. However many days you participate for the Grim Up North Running Team will look after you. With rural walks, noteworthy heritage and peaceful boating it will provide the perfect way to run the 127mile length (and a bit more) of the canal (routes to be adjusted to ensure marathon distance is achieved each day) . You decide how many days of this event you would like to participate in, starting in Liverpool the team will be there to support and encourage you all the way back to Leeds. A bespoke medal we be awarded as always to all participants, those completing all five days will receive a special edition hoody.
