Run The Grim Reaper 2025
2025-05-24 00:00 - 2025-05-25 23:59 | Grimsthorpe Castle Park & Gardens, Estate Office, Grimsthorpe, Bourne PE10 0LY, UK
We are delighted to announce that The Grim Reaper is back at the stunning Grimsthorpe Castle Estate in South Lincolnshire on May 24 & 25, 2025. Runners have the option of four solo distances – 10, 40, 70 & 100 miles – plus 40-mile and 100-mile team relay options. There will be two 10-mile races, one in the morning and a night version.

Expect a mix of estate roads, limestone tracks and grass trails. Trail shoes are recommended, especially in damp/wet conditions.

The new direction for the Grim Reaper

The Grim Reaper was relaunched in 2023 by Steve Cole & Laura Bailey, runners local to the Grimsthorpe Estate who compete in races of distances from 10km up to 100 miles. Their plan was to create an event that catered for runners of all abilities in a stunning location with a friendly, supportive vibe. It’s fair to say that the 260+ runners in 2023 feel they achieved that goal, judging by the 4.8* (out of 5) rating on Letsdothis.com.

Located at the beautiful Grimsthorpe Castle

The route is a 10-mile loop that covers beautiful grass trails through ancient woodland, limestone tracks, quiet estate roads and a stretch along a disused Victorian railway line. It also skirts around the picturesque estate lake before reaching the start/finish point in front of the castle itself.

We class this as an ‘undulating’ trail course with no major hills to contend with, making it ideal for those new to ultra-running, looking to take the next step to a longer distance or aiming for a PB. The course will be fully marked.

Route / Aid Stations

The 10-mile loop around the stunning Grimsthorpe Castle Estate includes a mix of grass trails through ancient woodland, quiet estate roads, limestone tracks and even a disused Victorian railway line. You also skirt around the beautiful Grimsthorpe lake before reaching the start/finish point in front of the Castle itself.

Medics

There will be fully qualified medics onsite throughout the event.

Aid Stations

If you are running one of the ultra-distances, you are expected to be self-sufficient and manage your own supplies. You are encouraged to bring your own tent/shelter, which can be left close to the start/finish point. There will be an Aid Station at mile 5 stocked with limited snacks & water. There will also be a toilet located at the aid station.

DETAILS

Food DrinkThere will be hot food and hot/cold drinks available to purchase throughout the event (from 6am on Saturday until 10am on Sunday).

Sorry no refund will be given as this will be out of our control. In the 10 years this has not been a problem.

There are three different distances plus a team relay to choose from: a super sprint, sprint and standard plus a relay option for the standard distance triathlon.

We are also running an Aqua Bike race. The first wave goes off at 6.30am and then every 15 minutes

Summer 10K
2025-07-11 00:00 - 23:59 | Coombe Abbey Park, CV3 2AB Coventry
Where is it?

Coombe Abbey Park, Coventry is run and managed by Coventry City Council. The What 3 Words location is here.

Parking costs up £3 for 1-2 hours. There is a toilet block next to the HQ on site. Coombe Abbey Park (CV3 2AB) is on the outskirts of Coventry and 6 minutes from Junction 2 of the M6. The closest train station is Coventry.

If you want to see what the venue is like watch the venue preview here.

Can I run with my dog?

No, it’s likely to be too warm, even later in the day to be running with dogs.

Course description

You’ll be running through woodland, meadow and over grass fields. Depending on the weather leading up to the event this could mean muddy, not so muddy or rock hard! There will be exposed trees roots, uneven surfaces and a few gates to navigate but the running will always have a view.

The route is undulating but not hilly. A truly great venue and route!

What does it cost?

We operate a tiered pricing approach. The earlier you enter, the cheaper the event but never ever will you pay a booking fee!

Before 11/06/2025 £16

After 11/06/2025 £21

Unaffiliated entrants pay £2 extra. Why not join your local running club or sign up the Big Bear Brigade and save 10% off entries for ever!

How far is the race?

10k! This might seem a bit pointless to mention given the name but this is different to a normal Big Bear Event. You’ll get the same love, a medal and some goodies but you can’t run all night!

I’ve heard you do cupless events?

Yes, but not for this event. Unlike our other events we will have some biodegradable cups with water/electrolyte available on the course. If you have a foldable/collapsible cup you can bring, even better but we don’t insist on it for our short races.

Has the event been run before?

Yes! We have won a Racecheck Gold Award for this event in 2024 and have won Gold awards in previous years. It has over 150 reviews scoring it at 4.8 out of 5! You’ll love it!

I’m not that fussed by a medal..

In that case our partnership with Earth Runs will be perfect! Rather than give you a medal you don’t really want (and to help reduce waste) we’ll give you a Big Bear Tree Token. Not only will a tree be planted for each token given out but the token is also full of wildflower seeds for you to grow at home!

Is there a cut-off?

Effectively 2 hours. This is how long the medics are booked for. The hope is that cut-off shouldn’t exclude anyone from entering. Please do contact us if that is the case. We do have to be conscious of the sunset too!

The Bridge Children's Triathlon
2025-07-13 00:00 - 23:59 | Dartford, United Kingdom
The 7th Bridge Children’s Triathlon will take place on the 13th July 2025. Entries are now open for the 2025 Dartford Bridge Children’s Triathlon. Every year we learn a bit more and we try and improve our events.
New swim course for this year’s children’s race. No lap’s just one loop for each race. 50m, 150m, 200, 300, this will make the swim easier for the children.
Due to time restrictions we are limited to only 50 in each age race wave. Boys and girls may be racing in the same wave. The children’s race is a stand alone race now. It was to hard to run it after the adult race. We need to have reopened the road by 10am so all waves will need to start on time.
We will be fencing off all areas this year for safety reasons. We will also be moving the Transition area down to the trees to give us more room. The Finish will also be moved 20m again to give us more room (see site plan)
Registration will only open at 5.30am for the children’s race. All children must be at the start area 15 minutes before their wave is due to start. Start times will be sent out the week before the race date by e-mail. They will also be posted on the web site
If you have any questions please feel free to ask before the day of the race. Estimated start time for each age group. This will be confirmed on 10th July.

Dormouse Challenge
2025-11-21 09:00 - 15:00 | Salcey Forest, NN7 2HX United Kingdom, Northamptonshire, NN7 2HX, United Kingdom
What’s a 6 hour event?
It is an event that enables all abilities of runner to run together (or hike/walk!). Ultimately you can run as many 5k laps as you wish in the time limit. You can run one lap in 20 minutes, pick up your medal and Big Bear drink and go home! Alternatively you can head out on your 15th lap at 14:55 and finish in 6:30 having covered over 50 miles! It’s completely up to you.
There is no pressure from us, but we’ll also see if you want one more lap! The format is great for people looking to run further than they’ve ever done before, do a long training run for future events or to enjoy a sociable event with your friends.
Where is it?
Salcey Forest is a Forestry England site with a café and toilets near Northampton. Use the post code NN7 2HX for Sat Navs . It is here on What 3 Words.
You do have to pay to park (we’ve negotiated a special offer of £3.50 for the day! We’ll send emails out to entrants to make this happen). That said, be a hero and car share, save money and the world!
The number 33 bus stops inside Salcey Forest (just after 9am) and goes between Northampton and Milton Keynes.
It is 18 minutes from Northampton and 9 minutes from Junction 15 of the M1. The closest train station is Northampton.
How far is the race?
You decide! The 3.5-mile off-road loop means your race can be 5k or even over 80K and anywhere in between. You decide how many laps you’re going to do on the day within the 6-hour time limit. If you’re looking to cover a marathon distance you’ll need to complete 7 laps (+ a little out and back) and a half marathon will be 4 laps (and a little long at 14 miles!).
Course description:
The route is along well maintained pathways. There isn’t a meter of asphalt and the pathways are mainly crushed stone or very well trodden open forest floor. Obviously being in the middle of a forest the narrower ones are covered in tree detritus and can become a bit muddy and grimy, especially when wet. On a dry day road shoes will be perfectly acceptable, on a wet day trail shoes may be a better bet as some parts can become a bit slippy.
What does it cost?
Before 21/10/2025 £37
After 21/10/2025 £42

The GRIM Challenge
2026-01-11 | Army Tank Training Area, Army Tank Training Area, Fleet Road, Aldershot, United Kingdom
About the event:
GRIM is a tough trail race in which you will certainly find yourself at times cold, wet and dirty, it is not an obstacle race, it’s a running event. We don’t build any ramps, walls or swings on the course. All the obstacles are natural, formed by tanks driving over the route or by incessant rain in the weeks leading up to the event. Of course at this stage we can’t guarantee the rain but it’s never let us down before! In a few places you will be crawling under cargo nets or wading though waist high water. The distance may not sound daunting but don’t take this lightly, on a cold December morning, the GRIM is a challenge and you will think it aptly named when you have run it.
Entries close on December 3 at NOON.

For runners arriving without a vehicle, Finish Line Bags may be deposited at registration, where they will be stored in number order and accessible to runners at the end of the race. Bags should be clearly labelled with the runner’s name and bib number.
Course Markings
The course will be marked with Centurion Ribbons and Centurion marker arrows for the entire duration.
Pacers
No pacers are permitted at any point on the route.
Crew
No crews are permitted at any point on the route.
Medical
There will be a dedicated team of race medics available throughout the race, including a static first aid team at the finish line and a minimum of one roving team out on course at all times. If you suffer an injury or accident that warrants direct medical attention, the medics will be on hand to provide you with exactly that. Contact numbers and full details of what to do in an emergency will be given to you in the pre-race information packs and again at race registration. Due to the nature of the course, ie, some remote and far from roads, the medics may take some time to reach you, or potentially be out of contact tending to other runners. In those instances, you should contact the emergency services on 999 AS WELL AS the race medics. Full instructions on what to do in an emergency can be found in the infopacks.
Kit
80% of the course is on trail. Trail shoes are advised.
There will be kit checks during the race and at the finish. Runners must carry the following mandatory equipment at all times. A time penalty of one hour will be imposed for any item found to be missing at any point on the course. Please refer to this page for explanations on the inclusion of the items below.
