Grades of Webster City Briggs Woods Ten Hills 5k

First of all the original 4.3k flagged course is soft but skiable as of 10 AM Monday, but the new loops...forgedaboudit! Using both GPS and Google Earth I entered the wild and wacky determination of grade percentage of our "Ten Hills" course. For uphills I measured from the start of when the uphill gets steep to the crest. For downhills I measured from the steep at the crest to the end of the steep grade (not the flat runout).The results are as follows:
#1 130' uphill with a 16'rise or 12%
#2 110' downhill (beside the 1st uphill) 12%
#3 170' uphill (at the base of #2) 15%
#4 315' downhill to the valley 6%
#5 210' uphill (from new loop) 14%
#6 320' long downhill traverse 9%
#7 235' uphill 19%
#8 375' downhill 12%
#9a 210' uphill (original on 4.3 k) 23%
#9b 215' next year traverse uphill to replace 9a 16%. #10 190' downhill (to long runout) 13%
