All 3 races start simultaneously with a mass breakout from Inveraray Jail down the Main Street to the Front Green and into Inveraray Castle grounds.
The first km and a half is on a tarmac surface through the estate grounds. After this the terrain is trail track the condition of which can be very variable depending on the weather. Expect lots of mud, bogs and very loose stones and you probably won't be disappointed! The race ascends 250m or so fairly sharply to the top of Dun na Cuiche where runners will go round the folly before descending to finish the race in front of Inveraray Castle making a very scenic run.
In addition to the main race of 4.5m/7km, there are junior races of 2.5m/3km (12-15yrs) and 2m/3km (6-11).
