Chris, we have had two events that combine sports. One is the "Mountain to Sea Event" from Mt Baker down to Bellingham, WA Bay. The event combines a run, cycle and sailing event.
We also had events in our "Nutfreezer" races with a "Sea and Ski". Hobie Cat sailing event on one day, and downhill ski race using NASTAR courses at a nearby ski location on the second day. The NASTAR system adjusts for age, sex, etc. A local pro sets the course baseline time each day. The Ski race counted as one or more of the races, and was combined with the sailing races for a total score.
