About This Event
The Grim Leodis offers runners a taste of everything that makes Yorkshire trail running special, wrapped into a 6.5-mile loop along the historic Leeds Liverpool Canal and River Aire. The multi-distance format allows runners to choose their challenge, with the same undulating route repeated for half marathon, 20-mile, and marathon distances. This Trail Running Association licensed event showcases varied terrain including canal towpath, riverside trails, and brief road sections, all fully marshalled and well-supported with feed stations every 3 miles. The race operates as a cup-less event, emphasizing environmental responsibility while maintaining the high standards expected from Its Grim Up North Running. Based in Kirkstall, the event provides beautiful views of two of Yorkshire's most significant waterways while offering a true test of trail running versatility. The 6.5-hour cut-off accommodates runners across all distances, making this an inclusive event for the broader trail running community.
