Riding The Surrey Hills

Starting on the fringes of the Surrey Hills, this ride takes you into their very heart and back out again, to explore a mix of the most popular tracks and hidden gems!

The Surrey Hills are one of the most popular MTB destinations in the UK. But in recent years, the focus on a small number of man made trails has led many to forget just what a great mix of open trail riding the area has to offer! From Winterfold Woods and beyond into the Surrey Hills, this is some of the very best riding in the south east, you’ll enjoy a series of climbs, descents with enough technical spice to keep things interesting, plus sweeping views and beautiful scenery. Another bonus with this area is surfaces that stay rideable year round, making it an ideal place to ride at any time of year!

Clarity on Charity: Our Statement

When we introduce a charity element to our events, we believe in in being completely clear about how much money will be donated to the charity, so you know how much you’re paying and where it will go. No foggy numbers or vague statements!

For this event, you must select either a £15, £20 or £25 donation to enter, and every penny of that donation will be donated to the charity (Comic Relief). This means that you are giving at the point of entry, and only need to fund raise on top if you really want to (but kudos to you if you do!) On top, we are selling the event t-shirt to raise money,and all profits from the sale of those shirts will also be donated to the charity!

We will announce the total raised and donated after the event.

Event Logistics

On the Ride

Once you’re ready to start, report to the start / finish area with your timing chap strapped to your ankle. Listen to the short briefing and ride across the timing mat as directed. As you go around the route, you will find bright orange signs and ribbons to follow. At route divide points, you will find yellow signs showing you which way to go to follow the Full, Mid or Short routes. These should guide you around the whole route, but use your map if you think you have strayed off course or have a problem with the route navigation. There are also emergency contact numbers on the edge of your map. Ride safely at all times, and remember that you are on public rights of way and roads. This is not a race, so please ride appropriately, and be friendly and polite to other trail users you meet. At the end of the ride, pass over the timing mat once again, and hand in your timing chip. For those interested in there ride time, these will be available on the computer screen at the finish.

Entry on the Day

You can enter the event on the day, although there is a small surcharge (so pre entering is recommended). Just arrive before the end of the registration period and pay at the desk.


Go to the registration desk on your arrival. If you’ve pre-entered via the internet or posted your entry, you’ll have a timing chip on an ankle strap to collect at the desk. If you haven’t pre-entered, pay at the desk and a chip will be allocated to you. Collect your colour A4 map at registration also. Next, get yourself ready to ride.

Following the Route

Follow the orange signs and orange ribbons (you will shown samples of these at the ride briefing) regardless of which route distance you are riding. Everybody follows orange. At route divide points, you will see a set of yellow signs, with “Full Route”, “Mid Route” or “Short Route” written on them, pointing in different directions. At this point, follow the right sign for the route you are riding. Once you get beyond the route divide point, you will start following orange signs and ribbons again.

(Please note, in spite of our best efforts, signs can go missing or be tampered with during the course of the day. Make sure you pick up a copy of the route map at event registration, and carry it with you for use if needed. We also send out GPS files to all pre entries prior to the event, so if oyu want ot have the route on your phone or GPS device, sign up online now!)

Food and Drink

Hot and cold food and drink and snacks will be available to purchase from the event centre before and after the ride. (Including our ever popular home made chilli!)
