Another vote for the Auburn Triathlon here. I raced it two years ago. Beautiful course with hills. The swim is in Folsom Lake and the run is single track on some of the Western States trails. Excellent food and beer after from local brewery. Denver to Sacramento is an easy flight and Auburn is probably a 40 minute drive east on I-80. There are a lot of brewery's and wineries to enjoy in the Sierra Foothills.
Clean Sierra water, good roads with great scenery and an excellent run course that may stop you in your tracks to take in the views.
