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…

9. Ironman 70.3 St. George, St. George, Utah, USA

It’s the race where Alistair Brownlee made his statement of 70.3 intent in May 2017 but, despite his course record of 3:41:58, it’s actually one of the toughest Ironman 70.3s on the circuit for us mere mortals.

The one loop swim takes place in the calm, if chilly, waters of the Sand Hollow Reservoir before the bike leg takes in rolling hills and the signature climb up – and through – Snow Canyon State Park. The run, meanwhile, includes scaling Red Hills Parkway and going through the Red Cliffs Desert Reserve, all under the scorching Utah sun.


5th today behind some amazing athletes. Couldn't have asked for much more out of today! Really enjoyed racing in St. George! The city gets behind the race, and some major competition makes the racing fun! Thanks to all those people that support me! You make all the pain and suffering worth it! #showyourstripes #timetofly #domore #TeamTYR 📷: @talbotcox
