Middle-distance triathlons: the 13 toughest?

Ironman 70.3, Half Iron, Middle-distance. Whatever you want to call it, 113km racing is on the rise. But which is the world’s toughest course? We crunch the stats to pick our 13 hardest from around the globe…

6. The Lost Sheep, Kenmare, Ireland

During the past 14 years, the Lost Sheep Half Iron Triathlon has established itself as the toughest middle-distance race in Ireland. Organised by Cork Triathlon Club, the race is limited to 400 competitors and is a surefire bet to sell-out each season.

The 1.9km swim takes place in the pretty Kenmare Bay before a consistently lumpy 83km bike, which takes competitors from Kenmare out along the ring of Beara peninsula. Along the way are a duo of monster climbs, switchbacks and a 150m tunnel. While the bike course may be 7km short of official Ironman 70.3 distance, the organisers say they’ve yet to find anyone asking for more!
