Grim Leodis 2025

An undulating 6.5 mile loop combining a mixture of canal tow path, river bank, trail and a short road section – A little bit of everything. You get to see some beautiful sections of the Leeds Liverpool Canal and the River Aire.

Route information:

Terrain: Towpath/Trail and road

Course type: Lapped

Support : The routes will be both marshalled and signed. Well stocked feed stations can be found every three miles.

Cut-off Time

There will be a cut-off time of 6.5 hours. All runners should complete the course in that time.

During the race 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 ban 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.

Know your route: We offer downloadable GPX files for our routes. Our routes are mainly off road and not every corner or junction will have a marshal. Please ensure you have a version of the route to help you navigate.

Withdrawal: If you need to withdraw during an event please let the nearest marshal know. In certain circumstances we allow runners to drop distances during an event. Please speak to the timers or RD at the end of your run.

Transfers/Deferrals: You can self-serve your transfer or deferral either on this website or “Let’s Do This” depending on where you booked. Please try not to change your event or details on the day as it causes delays and queues at registration.

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.
