missing a gear 

Surging one's pace too early or too fast during a run or race and failing to keep it. This often results in hitting the wall, and irreparably kills a runner's chance to run a good time.

Damnit! I tried to pass that group on a hill and I ended upmissing a gear. I fucked up the rest of my race!
