The Pacific Crest long course triathlon is one of a number of triathlons staged in Central Oregon each year, but it is the only one of its length. The standard format for a long course triathlon — sometimes referred to as a half-Ironman — is a 1.2-mile swim, a 56-mile bike ride and a 13.1-mile half marathon run, for a total distance of 70.3 miles. Legs may vary slightly from race to race due to course logistics. Completing such a race requires a commitment to training and presents an enjoyable, if lengthy, challenge on race day.

Several other long course triathlons dot the Pacific Northwest racing calendar each year. Some are established races, while others are as new as just their second year. For those multisport enthusiasts who find that the distance suits their fancy, the following is a list of additional long-course triathlons in the region, which may help for race planning in this or future years.
