Points System for League

For the purposes of the league, competitors will only be ranked against those in the same age class.

Points will be awarded in each age class in line with the IOF point system as used for WOC and EOC events. The first 40 competitors in each age class will score points as follows:

60, 54, 49, 45, 42, 39, 37, 35, 33, 31, 30, 29,28, 27, 26 ..1

A competitor may enter a higher class but will not score league points. If a competitor wishes to count in a higher age class throughout the season instead of their normal age class this must be declared to the league coordinator. For example an M50 rider may wish to compete on the A course. A competitor who enters a shorter class will be declared non competitive in the league and not score points.

Age Classes and Courses

To score points in the National MBO League competitors must enter the course appropriate to their age class.

Age classes will correspond to the courses at events as follows:

• A Course – M21 (Open men), M40, M20.
• B Course – W21 (Open Women), W40, M50, W50, M60, M/W 18 & W20,
• C Course –W60, Youth
• D Course - Score (Non-competitive)

For the purposes of the league, competitors will only be ranked against those in the same age class.

Course length

A course Estimated Winning times

• Sprint - 20 to 30 minutes
• Middle - 50 to 60 minutes
• Long - 90 to 110 minutes
• Ultra Long - 120 to 140 minutes

B & C courses will be of a shorter length but of similar standard of difficulty. The estimated winning times may be close to but not exceed the winning times of the A course when the age, gender or experience of the competitor is taken into account

D courses will be a score format using all of the controls from the other courses to provide a suitable challenge for novices to MBO. A novice may be new to orienteering, mountain biking or both. It will also provide an introduction to Orienteering style maps for riders more used to MBO Score (Trail Quests) events. The format could have a time limit or be a Spanish Score (collect all) format.

Expected winning times will vary depending on the area, but will be displayed at the event.

Further information regarding the character of the different distances can be found on the accompanying extract from the IOF rules. These can only be guidelines as the nature of the terrain will influence the style of event.
