Hi guys, new on BF with a quick question. If a 10% grade is ten feet of rise over a hundred feet, how is it considered hard? On my bike route there's a couple hills that rise at least 30 to 40 feet, and I can get through them pretty easily. I know that some of the 10% grades you guys talk about are sustained and long, but it doesn't seem too hard for me to climb. Can anyone post pictures of hills that are around 10%?
