I did a bike Biathlon early this year. It consisted of biking to check points (which were conveniently located up several STEEP hills) and taking a shot at a target using a slingshot the first time, and bb gun the 2nd and third time. Oh and there were also warm jello shots to take too.

Also I got my ass kicked on the ride. I ended up doing only 3 pulls and got dropped at mile 11.35. I kept going and eventually picked up with the B group at mile 20. It sucks because the B group is a little too slow while the A group is way to fast. Ended up averaging 20.5mph over the 43 miles. I think the A group was doing 23.5-24mph average when I dropped off.
