New to Open5 events?Introduction

An Open5 is an Adventure Racing style event where you visit as many controls as you can by bike and on foot within a 5 hour time limit. You navigate to each control location using an OS map, given to you at registration, with pre-printed controls on it (see example map extract on the right). Each control is assigned a value and you will be given a control sheet at the start (see example extract on the right). But beware - some controls are not live, so you can't completely plan your route before you start! The winner is the person who has collected the most points. You can make the event as hard or as easy as you like as there are no fixed routes. You can either run or bike first - it's up to you – as long as you collect at least one bike control and one run control.

The events are usually held in areas which provide a good challenge for beginners as well as regulars. We like to select interesting locations which have natural beauty for our events. Controls are located on paths and tracks of mixed-terrain and self-navigational around your chosen route is a key aspect. The emphasis is on having a fun day out at your own pace.

Your first Open5 event

We do try and keep things simple but invariably we get a good number of questions before events and on the day from those new to this kind of events. This little article will take you step by step through the day.

Before the event:

Sort out your kitEven if you are local to the event it will invariably be an early start on the Sunday morning. It’s a good idea to sort out your kit well before the weekend. Do you have all of the mandatory kit listed in the rules? First Aid kit, Whistle, etc.

What about your bike? If you are going to get it serviced don’t do it in the week before the event or if you do make sure you take it out for a few hours off road before the day. If you need to hire a bike give us a shout at Open Adventure and we can often point you in the direction of a hire company that can deliver to the event.

Sleep well.

The morning:

RegistrationTime whizz’s by so we recommend you arrive early. Park your car and come to registration. At registration you will receive a double sided A4 map, running / MTB numbers, and an electronic device called a Sportident (SI) dibber which is attached to your wrist.

The SI dibber is used to record when you started, finished and which control points you visited on the event. If you find yourself competing in number of similar events each year, you can buy a SI dibber from

The map we issue has a Ordnance Survey (OS) 1:50000 map on one side with the MTB controls (points you have to visit) already pre-printed. On the other side is an OS 1:25000 map with the foot controls pre-printed.

Look at the mapDisappear back to your car to collect your bike and any kit you might need for the day, food, drinks, clothing, spare shoes. Occasionally the start is right beside the car park so you can leave stuff in the car, on other occasions the start is a short cycle away so you might need to be able to carry anything you might need at the transition e.g. running shoes, extra food, etc.
