Friendly, inclusive, well-organised fun with great food. It’s always a pleasure to run with It’s Grim Up North — a low-key, friendly, helpful bunch who really look after their runners. Hot food, cider, cake and sweets all available at the finish line in abundance, plus friendly marshals and an inclusive atmosphere. Stephanie Innes-Smith

Very friendly and well organised event — great! Ian Rafferty

Runners’ paradise. Phoebe Little

Always great events. Really good selection of food, snacks and drinks. Very friendly and well organised runs. Angela Howarth

Awesome event. Well organised, fab marshals and great communication. Great event for anyone wanting to try a different distance. David Robertshaw

Absolutely fantastic — you will never find any better races than Grim ones. Thought the move of the registration place was better, though a portaloo at the start/finish would help for longer distances. The feed station was fab, as was the finish one. Louise Taylor

Fantastic, well organised eve. Kelly Baker

Lovely day out. Lyn Todd

Felt like you were with friends. Lovely event, well organised, friendly volunteers, a lovely run and a sausage sandwich — what else do you want. Andrew Davey

First 5k event with Grim Up North, very welcoming and very well organised. Will be returning for many more. Kristian Coates

Always a great experience running with Grim. Thanks to the whole team — everyone is so kind, positive and friendly. Really liked the registration over the road, great loos. There aren’t many marathons where you can finish, be given a bacon sandwich and wander back to your car with a medal and a warm fuzzy feeling. No stress, no hassle, just good running. So glad I chose this race for my first marathon — a flat course, spot-on running weather and an amazing atmosphere. Sarah Woffinden

Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
