I haven't done the race, but frequently train up there. I always come from the other end of the Aran. If one could race a loop from the South end, it would make a cracker of a course. Unfortunately not very practical.

It is a great ridge with some stunning views from the top, little chance for you to stop and enjoy them but return one day for a run out .

Worth noting it is higher than Cadair - but with none of the crowds.
