SLOW MBO - Holmbury St. Mary

This mountain bike orienteering event returns to one of our favourite locations in the heart of the Surrey Hills. There's a huge choice of routes over some of the best mountain bike trails in the South East and which remain rideable all year. On return to the event base, refreshments will be provided and prizes will be presented to the winners of the 2025/26 Series.

The event is open to anyone (age 12+) from experts to those looking for some exercise in the countryside. It will also count as the first event of the 2026/27 season.

You’ll be given a marked up OS A3 waterproof map and have 2 or 3 hours to plan your own route and visit as many checkpoints as possible. You can enter as a solo, pair or family team.

To participate you will need the MapRun App on your iPhone or Android phone. A link to download the course will be sent shortly before the event. The PIN code will be given at the start. It's important not to enter the PIN code until you are ready to go as your time will start as soon as you do so.

If you're new to orienteering and don't have a map board you can borrow a basic one to attach to your bike.

Start Times: 09:00am – 10:30am

Time Limit: - 2 Hours, 3 Hours
