Run 36:00 
First time I have ever cut a run short due to FDF's.
So many bites I had an 'allergic' reaction that I have never had from FDF's (or anything else) before... I killed easily hundreds of them but handily lost the war!! At times actually killed them by the handful that I caught out of the air around me!?!?!?!
Will utilized the hang back and let the leader take the Flies method, but he still got a LOT of bites
