Description	Its our birthday you can run if you want to :) Come and join us for our Birthday celebration. This trail running extravaganza has plenty to whet the appetite of participants. There's the choice of a 6.6 miler, half marathon or a marathon  looped course making this the perfect day out for runners of all stripes. The Kirkstall Abbey based course is a multi-distance trail run through the glorious trails surrounding Kirkstall Abbey in Leeds, all courses will be run over a mixture of field, pavement, trail and canal towpath, giving participants an exciting blend of different terrains. The route consists of an 6.6-mile loop which plunges participants through sprawling paths that weave alongside the beautiful River Aire and Bramley Fall Park. There's river crossings and twisting trail elements in the loop, ensuring that you're unlikely to forget this fantastic day out. Those in the 6.6 miler will run a single loop, those in the Half Marathon will run just over a loop, those in the marathon will run 3.

During the race and important things to note:	We try to be cup-less: Our feed stations are normally around every three miles and offer drinks and a range of food but please bring your own re-usable cup or bottle. Headphones: Most of our courses are off road but we still prefer you not to wear earphones and due to oncourse incidents, we have taken the decision to ask you not to wear large over ear headphones. These block out any other sounds and don't allow runners to hear marshals, vehicles or other users of the route. If you do need to wear earphones, then please use bone conducting earphones or "one in one out" in ear pieces. Please note, there may well be unmarshalled road crossings. Transfers/Deferrals: You can self-serve your transfer or deferral either on the Grim Up North website, this is a free service. Please try not to change your event or details on the day as it causes delays and queues at registration. Please note if you need us to transfer your entry we may apply a £5 charge. If you are struggling, injured or want to retire please notify the closest marshal. We no longer mail out a race brief as most of the information is here on the website however we advise you to visit our FAQ section and join the “Grim Up North Chat” group on Facebook which will help with any other questions you have.
