Running
A short burst of speed: 62% faster than walking for about four and a half seconds, then you need a breather.
Running empties a sprint tank in 4.5 seconds flat out. Once you stop, it has to rest for just under a second before it starts refilling, and it takes about 3 seconds to fill completely.
Land animals run a little slower than you walk, so a chase is one you can win if you commit to it. Birds and fish are another matter.
