TrailO Ranking & Selection - general information

The British Orienteering Selection Policy for TrailO in 2018 is set down in three documents:

TrailO Selection Overview, which can be accessed here

TrailO Selection for 2018, accessed here, and

TrailO Selection Panel for 2018, accessed here.


The TrailO Steering Group operates a Ranking List which is used for selection purposes. An explanation of how it works is given below.

Links to the latest Ranking List and the points scored from the individual Ranking Events held up to now this year are to be found at the foot of the text.

1. Who gets ranked?

The Ranking List was originally developed to assist the Selectors make their decisions, so it only contains the names of those trail orienteers eligible for selection for the GBR team. BOF Members (except those from NI) are included in the ranking calculations. Since many/most NI orienteers compete for Ireland rather than GBR they aren't automatically included, but if they declare an interest in selection for GBR only rather than IRL then they can be included from that moment onwards.

2. Which events provide ranking points?

Only events selected in advance by the TrailO Development Steering Group (TSG) are included in the rankings. These will usually be the British Championships, the JK and the Irish Championships. When overseas events are included which take place over more than 1 day, then the results are combined. Only Elite classes earn Ranking Points.

3. How are the points calculated?

The full calculation details are provided in Brian Parker's Technical Note

4. How long do scores stay on the Ranking List?

The Ranking List is basically a rolling 2-year list, so events "fall off" the list on the 1st January following the date the event happened OR when the event is replaced by its 2-year successor. So for instance BTOC 2012 fell off the rankings on the 1st January 2015 (as there wasn't a BTOC 2014 in 2014 itself) whereas BTOC 2013 fell off on the weekend of BTOC 2015.

5. How are the points combined into a ranking?

Only your best X scores are combined. At the given date when rankings are considered for selections, the total number of qualifying events are added up. If there are only 5 events then it is best 3 to count, if it is 6-9 then it is the best 4. 10 and above it is best 5.

6. What is the "Planner's bonus"?

A significant number of the Ranking Events are planned by a subset of the contenders for WTOC and ETOC places. In order to encourage people to plan and control Ranking events, planners and controllers of Ranking events during the qualifying period, who therefore do not have enough qualifying results, will have the ranking points from their lowest results doubled up. Those who have planned/controlled (or otherwise given up on a competitive run to enable an event to take place) are allowed to double up their 3rd score (if best 4 to count) or 4th score (if best 5 to count). If it is best 3 to count then the 2nd score is only doubled if the competitor does not have the requisite 3 events.
