I should have mentioned in the first post, to get a real view of a particular hill, you have to look in small scale, so map a mile or less of a route to get micro measurement of a hill. My hill, in Las Cruces NM starts where hwy 70 intersects I 25 and goes east for about a mile and a half. The worst part, about a mile, I measured at 480 feet with an aircraft, very accurate altimiter. But map my ride shows it less vertical. Mabye I misread the altimiter? Map my ride and the altimiter agree on a longer distance, from work to home so maybe there are some small discrepancies in there, or I just wrote down a wrong number, poor math skills, can't even subtract right.
Most likely my mistake, and then I used a bogus number to calculate.
The hill does have a flat spot, and a dip for an underpass as I ride the hwy frontage, so I figured the steepest parts had to be 10%, but the map my ride says, 7% and average over the whole hill on a longer distance scale, a wimpy 4%! Still enough to melt down a motor though! That discouraging, but it was 105f, and the motor was a crap brushed model. Some hills I rode the other day that I did find pretty steep mapped out at 13%. Gee no wonder my wife was not happy! She started refusing to go hiking with me 25 years ago :lol: I never learn do I.
The program does have a few flaws, I keep getting a route that goes out on the road, and then beelines back. Not sure what I'm doing that causes that, but most likely some kind of spazzing out with the mouse as I click. I looked at a route we used to gravity race in my youth, from the top of a pass to Kingston NM. This road leaves I 25 going west near caballo lake about 60 miles north of Las Cruces. Holy crap, no wonder it was fun. Those ramps into the turns are mapping out in the 15 -20 % range. I can't belive nobody died back then! Ah to be young and durable again.
It was interesting to see how much less steep the 10% hill I talk about really is. It's still a steep climb, but only one part of it is 7%.
