A couple months back I decided for no reason to train and race in a Duathlon. I knew I wanted to do a muli-sport, knew I wasn't a competitive swimmer, and settled on a Duathlon. A duathlon is a two-sport race hence the name where you run, bike then run again. Not to be confused with a bi-ahtlon that combines cross country skiing and shooting things with a rifle! There are various distances just like in a Triathlon from sprint, Olympic to full. Read official distances here.
I consulted with a talented triathlete I know named 'Jim' who recommended a local race held by 'Wolf' in the San Pablo Dam area, Orinda, CA. I knew the area was hilly, beautiful and given the next race was a month away jumped at the chance to race it.
