Ultra biathlon –
6 hours long, 1 1/4 long wooded trail loop.
End of the loop is range with biathlon targets at 50 feet. Each loop you shoot 5 rounds either off hand or prone 1 point for prone, 3 points for off hand. Bonus 1 point for cleaning the prone and 5 points for cleaning offhand.
Thinking of having a leader board outside the range so you can see where you stand to help decide what position to attempt on each loop.
Winner has the most points. Then we put the rifles away, break out the beer and eat fried chicken!
