This is the Griggstown Grinders' Longest Day Ride ... a week or two late following last week's downpour.
Steve was due to lead but went down with some sort of lurgy, but Diane turned up having been washed out from her vacation trip.
So, close to 33miles and according to ridewithgps.com, over 2000ft of climbing, it seems this site accrues every element of where the road is uphill, thus accumulating every single foot ascended. Some sites don't give such a high figure as this. I suspect their sample rate may be lower.
