Races run on Saturdays or Sundays, mainly in Wicklow.
These races are longer than the very popular Wednesday night league races and tend to be run on open mountainside.
As a rule they are not marked and runners would be expected to be able to find their way from a published route. No electronic navigational assistance may be used for championship races. You may record the route on a device for post race analysis, but you may not use it for in-race navigation.
