I was the one with the battery, but I'm going to save that for racing.

Sometimes I visualize Pac-Man when I'm running intervals. Wakka-wakka-wakka-wakka, scoop up a power-up. Sometimes I'll visualize a flaming ball of energy at my crown and/or center.

Running, vary your route so you have different things to look at. On the path that you cycle on, notice little details that go by too quickly when you're on the bike. It's always amazing to me that the same route can look completely different on foot, on the bike, and in the car. (Also on the motorcycle, which is extra interesting, considering the speed is usually pretty similar to car speed - you just notice different things.) I can't focus exclusively on form, but I like to be in my body a lot when I run, which is quite a bit of engagement.
