i'd also suggest something to those who have to stop. this only works for the road, though. Weave up the hill if you feel you can't make it going straight. I have a psychological panic freakout (with tears) that gets triggered if my heartrate goes to high. I can fight through it, but it stinks crying in panic as I fight my way up. so last time, I tried weaving. 10 feet width of a weave was sufficient to turn the hill into a baby. I felt silly zig-zagging, but the method could probably render any steep hill into nothing. this is more difficult if you are riding with many other cyclists or a narrow car-bound road. but it is something to try.
