The course has been planned on the Mourne Mountains 1:25,000 map (1st edition) from Harvey Maps. There is a 2nd edition 2014 version of this map but the controls will be placed on features that are correctly shown on both versions. The OSNI activity Map of The Mournes won’t be as useful. Both maps are available from any good online or local retailer – including our superb sponsors – Jackson Sports. WE DO NOT SUPPLY maps as part of the entry process.
