Elysian Harriers, history question

Hi, i have been trying to find information regarding the Elysian Harriers running club who i believe to have been based somewhere near Dublin in the early 20th century, but basically come up empty with all searches. So perhaps somebody who has been in the athletic club scene for a long time might have information?
The reason is that my grandfather of whom we know little about was in this club, so finding any details on where it was etc might help uncover more information about him.

Thanks in advance!
