Ok, so I found a bright white rocknear the last place I tipped over and that is my marker. Then I move it to where I make it. For a while, I passed the rock, if only for a few feet every time. I think it was part technique, and part "there is the rock gotta make it". But the last three times I didn't and last night it was by thirty yards at least.
What seems to happen is if I get below a certain cadence pedalling, I just can't the pedals turning faster again and it turns into a viscious circle of reduced speed, lower cadence, reduced speed til I cant turn thm and I go down. I am just glad it's a short drop.
Any other ideas for anyone to help me out?
