The GrimReaper UltraMarathon is a non-stop race in teams or as solo runner/walkers that continue through the night for those doing the longer distances Incorporating multiple 10 mile loops around the grounds of Grimsthorpe Castle Estate. Teams can be made up of between 2-4 persons and will share the distance out between the team members. Teams and solo runners/walkers can choose between 40 ,70 or 100 miles. All race distances start at the same time and all have the same time limit of 26 hours. Camping available and a great atmosphere guaranteed.
( 9.30am start for all solo and team categories- EVERYONE starts at the same time ). All event distances and categories have the same time limit of 26 hours
All team categories are to use 1 chip timer that acts as a relay baton. This can be carried by one person in the team and that person can be joined by as few or as many team members as you want on the laps. The team members decide who runs which lap and how many people in the team can accompany the timing chip on the laps.
Runners to complete approx 4 , 7 or 10 laps of 10 mile loop. Each competitor will be given an electronic timing chip which they must place in the timing receiver at the far end of each loop and at the near end of each loop. When you have the correct number of verified laps you have completed the race. After completing each loop you will arrive at the organisers tent where you have access to your kit. The route is beautifully varied incorporating hard limestone trail, grass trail and tarmac trail with fantastic scenery and wildlife on show.
Grim Reaper competitors must be at least 18 years of age on the day of the race.
Even if you have never competed in an ultra marathon before, Your physical fitness will only get you so far and your mental toughness will determine whether or not you cross the finish line. This is an event that tests your endurance and stamina, not your navigational skills. Many Ultra races require a certain amount of navigational skill which frustrate some entrants.
These entrants will be relieved to know that no map skills will be required as the large looping route will be clearly marked. The organizers will provide water, tea coffee, a selection of food (but please don’t rely on this as it may not suit your dietary requirements) and toilet facilities. As the estate is privately owned spectators will only be allowed a limited amount of access, which will be decided nearer the time. If spectators want to volunteer to assist with the running of the event though they will be able to stay on the estate for the full duration of the event (please use contact page to request to volunteer)
Supporters are welcome to attend - Please bring your family and friends to pic nic in front of the castle and support you. Thevenue has a beautiful adventure play area for children , fantastic wide open spaces to pic nic in fron tof the castle.

Recommended Minimum Requirements For Solo Entrants
Each distance is open to both elite and novice runners but we do recommend having a certain fitness level for each event.
The time limit of 26 hours makes the 40 mile distance very achievable for even the slowest of entrants.We would say though that a person entering this event should have a reasonable level of fitness as a minimum.
The 70 mile distance is still very achievable in 26 hours but we would recommend a good level of fitness to complete.
The 100 mile event is very challenging and is ideally suited to runners who are extremely fit, healthy and experienced ultra runners.
General Information for Solo Runners
