But this time after you come to a momentary stop I want you to ease off the forward pedal pressure even more and just enough so you feel gravity pushing your foot back up which at the same time will mean you will roll backwards ever so slightly.
And it’s not just your feet that ratchet back, but your bike and your whole body will move just slightly back too. At first this may feel strange, but it’s the basis for maintaining a balanced track stand.
You may need to experiment with hill steepness, the steeper the slope the more pronounced and immediate the roll back feedback will be, but the more power and pressure you’ll need to hold you in place, and then start up again with your forward foot pressure.
Practice until this feels normal and natural!
