Ahh bugger! We have lots of log stepups too and they really freak me out. I find that as long as I keep practicing at one particular place where they have lots and lots, of all different heights, I can sort of work my way up to bigger ones.

But if I have a few weeks without doing many, I have to start again to get my confidence back and also I am doubly squeamish at any I have ever fallen over.

But I'm kind of the opposite about the HR. If I know one is coming up, I'm pedalling like hell to make sure I have enough momentum to overcome my crappy technique! So my HR will be through the roof!

The other thing that really helped was to do a session with a coach who is big enough to catch you when he spots you over them!
