Does Coffee Give You Energy?

Back in the day I used to drink coffee all day long not knowing or caring about my health. I don't think it does anything for me, irregardless whether it's decaf or not. But the smell and taste is yummilicious. Now I rarely drink it. If anything 1 or half a cup a week, and many weeks I just don't drink it.
But if I do drink, then this is how I do it:
     - fill cup up with soymilk and drink half of it
     - add a tiny spoonful of a creamer for flavor
     - fill the rest with coffee
Yes, it's a bit watered down but I get the taste and smell of it.

About an hour after I took a 15min break and headed to the gym for a quick workout. Mind you, these little workouts just help keep me moving since I have a desk job. I really don't want my rear end to resemble a Mack truck! So not pretty, unless you're like Sir-Mix-A-Lot!

This is what I did today.
incline of 2.5:
     walked 2min
     ran 2min at 4.0
     walked 2min
     ran 2min at 4.5
     walked 2min

incline of 0:
     walked 1min

stretch (I keep forgetting to add this part)

Usually when I run, the first 2min or so is a lil tough when it comes to breathing. But afterwards my body adjusts and I'm fine. So the first 2min run at 4.0 pushed me. But the second 2min run at 4.5 wasn't so bad. It actually felt pretty darn good. Now is this the coffee kicking in? I don't know. I've read reports where some say that they'll consume some caffeine 30min or so prior to their run for a boost of energy.

Does this happen to you?

Do you always consume caffeine prior to running, biking, swimming, etc?

What I also did today was change up my routine. I've been reading that starting out slower and then increasing your pace will help one not tire out so easily. So maybe this was the trick. Ahhh....guess we'll find out tomorrow.

And no, I didn't do my 30min run this morning. I left my vibrams at work. I was so looking to run in them. Tomorrow's another day.
