Morning exercise is limited to the following:
1. Races: Rarely are races super close to my house (At least not the ones I pick, whoops). Plus, I have a "whoops I arrived too early I guess I'll sit in my car for 45 minutes." It happens all the time. So, with drive time and wait time, I'm usually not running until about 2 hours after I wake up. My body is okay by then.
2. Marathon training: In the midst of it, we would have 5-6 hour runs. It was summer. That means we started running between 5-6am. Oh god. It was awful. And by awful I mean really really awful. But, by the time we'd be finishing up the run, it would be way too hot. Stupid Southern California. But, it had to be done, and we certainly weren't running very hard. The runs were long, but very, very slow.
3. Personal training: With the exception of ten minutes of walking on the treadmill (Sure, sometimes I jog, but that's a personal choice), there is no cardio involved in my training sessions. So, it's not too rough.
The main issue is, my stomach is not a morning stomach. When I wake up it's all "is this real life???" I also can't eat for hours after I wake up. I've been awake for about an hour now, and the thought of shaking up my stomach contents (or adding to them) still makes me want to hurl.
So, yeah. I will probably not ever morph into Wake Up Early And Run Girl. But I am a rock star at being Run After Work Girl. When I'm prepared. It's easier when it's still light out, but I can make do with street running.
Not everyone can be a morning runner. And I'm okay with that.
