We have members of all shapes and sizes, individuals and families, from juniors through adult to veterans.

3Rockers are at all levels of fitness and of orienteering experience, from beginners (maybe just like you?) to some who have been orienteering since the sport started here in the 1960’s. Remember, we were all beginners once!

We have fitness training at UCD, Belfield, twice a week and we stage orienteering competitions all year round, including night events, mountain bike orienteering and street or park events, as well as the conventional forest or mountain Leinster League or Championship events. Fitness (running) training is at 6.30 on Mondays and Thursdays at UCD, Belfield.

Not just Competition!

Orienteering is a sport with a lot of different aspects and opportunities for you. If you are not that interested in competing, we have lots of other things you might like: mapping, course planning, organising competitions, controlling (like refereeing events). Orienteering also has quite a high level of IT or computing, from mapping through event admin and results, so you might find your particular niche there.

Where do we go orienteering?

3ROC have an extensive portfolio of high quality maps for a number of locations on the eastern seaboard of Ireland. These cover a wide variety of terrains from open mountain to parkland with a bit of everything in between. Customised maps are typically printed off for 3ROC orienteering events at a scale of 1:10,000 or 1:15,000. Among the areas currently mapped are:

  • Three Rock Wood, Dundrum
  • Pine Forest, Rockbrook
  • Phoenix Park
  • Farmleigh, Castleknock
  • Clarabeg, Laragh, Co. Wicklow
  • Carrick Mountain, Glenealy, Co. Wicklow
  • Carlingford Mountain, Co. Louth (Details on the local geology here)
  • Glendalough, Co.Wicklow
  • Griffeen Park, Lucan
  • St Catherine’s Park, Lucan
  • Devil’s Glen, Co. Wicklow

Club equipment and clothing

You will see 3ROC members running in their distinctive red and black orienteering tops at events all over Ireland and further afield. You don’t need one, but once you get into the sport you will find that an O-top is a useful and comfortable thing to wear orienteering. We stock a supply of club gear at reduced prices for members. We also have SportIdent (SI) card timing chips at a reduced rate for our members.

Club O-tops are available from Lindie: Junior sizes are subsidised by the club.

We have also got a great Regatta soft shell jacket which is weatherproof and comes in red and black with the club logo embroidered on the front. These come in sizes from XS up, but not childrens’ sizes. We also have lightweight Bryzos running jackets, running hats, O-trousers, buffs etc.

We also have black fleece beanie hats with the embroidered 3ROC logo, ideal for those cold O-days!
