My cadence monitor has been broken (wires) for a little while so I haven't been using it. However I much enjoyed it back in the days. I find that when I'm not paying attention and becoming tired, it's often related to my cadence dropping to the 70s. When I notice it, I downshift to an easier gear, spin at about 90rpm, and my morale is on the rise again!

I think I'll work on fixing it after my race this weekend.
