North Face Endurance - Wisconsin

I did it last year during a back to back weekend...had this one on saturday and one in Ill on sunday....was gonna do the 50K due to it starting before the marathon but it was my first back to back weekend so opted for the marathon....had 2 miles left to go and was with another runner who was finishing the 50 miler and the folks at the last aid station (which we later found out was the aid station for the relay) sent us both the wrong way and we did a 6 mile loop....thank God it brought us in a loop and back there as we had no idea where we were when we would be back or anything...was sending FB messages to the RD on their site and they finally figured out what had happened.....so I ended up doing a little more then a 50K that day hahaha. I knew something was wrong as I didnt see my color flags and the 50 mile guys and some others were there so it was the start part of the 50 miler and 50k that looped in somehow, I wanted to turn back but we knew he was almost done due to his mileage and he said no this is my colors and I would say well I only have a little more then 2 miles also and my color isnt here cant imagine the finish being different for out races with the same distance to cover?  It was pretty, there were some nice trails and also open prairie type fields....hot but was expected.
