Who are London & South East Adventure Racers?

We are a local community with a shared interest in multi-sport racing. While our focus is adventure racing, our members participate in everything from mountain marathons, trail running, kayaking, mountain bike and foot orienteering, climbing, sportives and more. Find out more at the London & South East Adventure Racers Facebook group.

Our first MTB Score series of five events in 2015 was a great success and we are back in 2016 with a set of brand new planners and locations.

What is a MTB-Score Event?

MTB-Score is a fun and exciting form of orienteering on bikes. Unlike MTBO which uses specialist maps, MTB-Score uses regular 1:25,000 scale Ordnance Survey maps which are more familiar to most people. Primarily off-road events, a mountain bike is the preferred choice, however hybrids and cross-bikes can also be used.
Depending on the event, between 2 and 7 hours are allowed to visit as many control sites as possible in order to maximise the points total, making route choice and navigational skills a high priority.

Events are open to all abilities and ages and racers can enter as either solo or pairs.

Where are the Events held?

Events are held in various locations around the Southeast where sufficient space and interesting terrain is on offer. Event venues will usually be a pub or sports centre.

What does the map look like?

Competitors are given a pre-printed 1:25,000 Ordnance Survey map with up to 30 control sites of varying point value positioned on bridleways, byways or forestry trails.
