Very interesting and informative. I’ll have to try some of this stuff out.
(I don’t know how on earth you can drink coffee before going on a run, but that’s just me. I would suggest trying green tea for all of the people out there: it doesn’t make you feel like you just drank battery acid when you have an empty stomach, it doesn’t have as much of a giddy high or a crappy come-down, and it’s way, way better for you in general. And cheaper.)
