Popular Event

The ever popular obstacle course starting and finishing in Chiddingfold is back. This year there will be a special team event and inflatable tubes to crawl through down by the river.

The route of run-forest-run is about 11km of cross country racing that includes about 1km of obstacles in the forest at the half way point.

Run to the forest, jump around the trees and then run back to the village. How hard can it be? Itll be as hard as you want it to be. This is a great race for teams, families, beginners and experts alike.

Run-Forest-Run route


The route of run-forest-run is about 11km of cross country racing that includes about 1km of obstacles in the forest at the half way point. Please note that the forest is private property and that entering outside race times is considered trespassing.

If you forget everything else – follow the little yellow arrows. There are over 100 arrows on the 10k course – that’s one about every 100m – so if you run for more than 2 minutes without seeing an arrow then turn around and retrace your steps. Two people did not follow this rule last year and got lost for an hour.

The course is mostly off road and on muddy clay paths with some sandy sections. It can be done in road shoes, but you will probably be faster wearing shoes with some tread. Wear clothing that allows you to move freely if you get muddy or wet. Expect several of the sections to be muddy and slippery with concealed tree roots, so be careful – it’s better to slow down and stay on your feet than to slip on your coccyx and hobble the 5 km back to the village. If it’s raining and you run slower than 9 minute miles, we recommend that you wear a waterproof layer to stay warm. If you run faster than 7 minute miles then you will literally be steaming if it rains. Try not to show off too much.

The outward run is on public bridle paths and takes you through thick mud, minor roads, a farm and a heavy clay path in Frillinghurst forest before arriving at Fowlshatch Copse where the obstacle course is set. At gates and pinch-points, outbound runners have priority, but please be courteous especially if the inbound runner is doing 6 min miles and you are walking.

The map shows both the run and the obstacle sections. There will be a marshal near the river to offer assistance, should you fall in. As a general rule in the obstacle course – if you get into difficulty then make some noise. There will be a marshal or another competitor nearby.

If you see another competitor in distress, then please don’t use them as another obstacle. Please offer a helping hand. We have a hero of the day award, so let a marshal know if someone has been a star!

Please stick to the paths inside the forest, there are several fallen and dangerous leaning trees away from the event paths. We don’t want anyone hurt!

The return run retraces the outward path. At all gates and pinch points – please concede priority to outbound runners. Please listen to the marshals at all times and do as they say. They are there for your safety.

At registration, you’ll collect your number, timing chip, T shirt and safety pins. There will be a map of the route and some photos of the course. Free Tea and Coffee is available to Runners and Marshals. Bacon butties and Jane’s special Lemon Drizzle cake are available when you finish the run.

The race start is just outside the Race HQ. Your time will be taken as you cross the start line. Please don’t bunch up at the start. If you’re fast, then come to the front. If you’re going for fun rather than speed, then please let the faster runner get away. If you want to run with your team, then approach the start together and be nice to the start marshal. It’s her decision!

There is a very narrow and sharp turn just past the church at about 800m. Please turn right IN SINGLE FILE. There will be a marshal on the corner who is really good at shouting, so don’t be the runner who makes him practise on you because you’re running on a main road on a blind corner.

The finish line is at the Race HQ. Be careful when you turn left onto the main road and head past the church. When you cross the finish line, the timer will stop and you can remove your chip, collect your medal, check your time and go into the Race HQ where you can get refreshments and a bacon butty.

Please hand back your chip at the end, otherwise we will have to hunt you down to get it back.

There is a bacon roll (or vegetarian roll) for all runners and marshals as well as tea, coffee, Jane’s special Lemon Drizzle cake and juice available. Awards will be presented at the time shown at the top of this page.


If you're in a team then please use the same team name for each entrant (you can enter all at once or at different times - you can all group together at the start line).

You can also enter in teams of 4 or 8.
