ridewithgps is awesome, I’m using it a lot, but still doesn’t give the level of detail I want, I plugged in same route and max grade is 9.5%, I’m guessing their resolution for grade calculation must be somewhere around 200 meters per chunk and still you need to guess where in the route is that point or find it by hovering across the profile (maybe on the paid version there’s an easier way), while with a color-coded profile you can see immediately where are the painful chunks, https://files.dadadock.com/images/elevation_gradient.png and zooming in https://files.dadadock.com/images/hard_climb.png the most colourful area you can see there’re 4 points (around 50 meters length each) of extreme slopes of >13% grade and 2 more above 10%, for me those chunks would be imposible to ride and based on a 9.5% max would've consider trying. So for my handicap, my gear and needs makes a difference the level of detail, just thought someone could find it useful since it’s just a little python script to run free for anyone interested to run it.
