What do you consider to be elevation?
I have been noticing postings concerning average speeds and how much they vary and many times the speeds vary because all of us live in different topographies. When I go on a bike ride in the wheat fields of Washington State...my elevation starts at about 1000 feet and as I do my bike rides I gradually climb to 1400-1600 feet over the course of 6-7 miles towards the foothills. Other times I can go upwards of 2600 feet when I decide to head on into the mountains a bit further. So....what is your elevation, and what do you consider to be tough ride?
