The extraordinary course is widely known as one of the most challenging yet most scenic and rewarding on the Ironman 70.3 circuit.

The race as a whole is an athlete favorite. In 2017, out of all Ironman 70.3 races across the globe, the St. George event received two major Athlete’s Choice Awards from the Ironman organization: Best Race Venue Experience and Best Host City Experience, according to a previous St. George News report.

As the county prepares to welcome athletes and put on a race of this magnitude, a host of events have been organized and road closures announced.
