As well as working on form I'm trying to be conscious of a desire to ease off and instead try to push for another gear.
... and isn't it surprising when you find that there is another gear and you can engage it?
Surprised the hell out of me in my last run, I can tell you ;-)
Good luck with the races. I hope all the training works well and you put in a performance you are happy with.
Thanks. It's a great feeling when you can override the brain's attempt to hold you back. Training the mind is just as important as training the body.
