Note on the W21E/W21L classes: Based on the number of entries received, the W21L and W21E classes have been amalgamated. The resultant class will be called W21E; it is the same standard as a W21E course, but the length of a W21L course. The length of the course has been chosen based on finishing times in these classes in previous competitions held on this terrain.
The Black Lakes are situated on the rough open mountain terrain of West Cork, which was last used for Irish Championships in 1999.

"I've been on The Black Lakes twice. The first time in 1996 at Shamrock O-Ringen, and the second time 2007 at an OK Linné training camp.
I remembered the terrain as quite varied, from flatter marshy areas to technically difficult slopes. All in all, a beautiful and tough area that was really enjoyable, especially the scenery at the lakes!"

Like the Black Lakes, Crohane features rough open mountainside with considerable rock, marsh and contour detail
that has been typical of the Shamrock O-Ringen. The runnability is variable, and dependent on the rainfall in the weeks preceding the event.
In 1998, Crohane Mountain was the scene of the first round of the
Orienteering World Cup.

Muckross (Killarney National Park) is an old forested estate beside the world famous lakes of Killarney, with a wide variation in terrain type.
This was the scene of the World Cup Relays in 1998, and the area has been newly re-mapped for Shamrock 2009.
The forest is mostly deciduous and fast-running, with many paths, and with rocky, steep and contoured parts.
The open fields interspersed with rocky forested sections will make for an exciting finish to this year's event.
