Tri Burgh is a standard Olympic distance triathlon consisting of a swim of 1500m, a bike ride of 40km and finally a 10km run. The course is varied and includes challenges specific to the course and the geography of west Mayo. It will take place on the 4th June 2011. The swim is an open-water course in Clew Bay - wetsuits are mandatory. The bike route is generally a circular route, but has an out and back leg taking in the magnificent Doo Lough Valley. This has a fast downhill section which is a climb on the return. The remainder of the bike course is on generally flat ground allowing the participant to take in the spectacular scenery.
