2020 will be our sixth MBO Score series and we have planners lined up to test your navigation and time keeping skills! Held mainly on Sunday mornings throughout the year, these are 2 or 3 hour Mountain Bike Orienteering events run using the MBO Score format. Events are run by SLOW and London & South East Adventure Racers in affiliation with the BMBO.

We have 4 Virtual MBO Score Courses available using the phone based App MapRunF which you can go and try at any time.

Small Area Format (SAF)

Events will usually include a choice of 2 courses, 3 or 2 hours. Both options will use the same map and checkpoints but the 3 hour one may be run as a Small Area Format (SAF) course.

For SAF, the checkpoints will be labelled red and blue, you choose which colour to start on and collect as many of that colour as you wish until you swap to the other colour. Once you’ve swapped you can’t revert back to the original colour. Points will be evenly split between the colours. For the 2 hour course the colour has no significance and you can visit the checkpoints in any order.

This example Mogador event  map shows our final event of 2018 redrawn as a SAF event.

Series Prizes

Series prizes will be presented to the top 3 finishers in the following categories:

Male Veteran (50+), Male Senior (18-49), Female Veteran (50+), Female Senior (18-49), Youth/Junior.

Series rankings are based on your top 3 scores from this years events. To be eligible for prizes, participants must have attended at least 2 events.
