I love coffee.  Probably even more than I love running.

I drink about a half a pot of coffee most mornings, and if I’ve got an early morning gym session, I bring my to-go mug of coffee with me.

So of course, I’ve thought about running with my coffee as well.

Obviously trying to sip a steaming cup of black coffee while running isn’t going to work so well, but I’ve come up with the next best thing!

Caffeine is a well-known performance enhancer as long as you don’t overdo it.  A little goes a long way and for me, that’s not much.

I love racing with starch instead of sugary gels, but I’ve found that adding a little bit of corn syrup pumps up the glucose but does not sour my stomach.  But with only one teaspoon, it’s not quite sweet enough for me in this recipe, so the liquid stevia helps with that.

Feel free to adjust according to the amount of sweetness you like!
