I used to run 5 miles a day M-F and then 6.5-8 miles Sat- Sun. It's early in my pregnancy (6 weeks), but my energy is ridiculously low, so I've reduced that to a 5k each weekday and 5 miles each weekend day. After my run today, I had to take a 2 hour nap and I'm STILL wiped. Am I exercising too much?
Also, while I'm not puking (much), I cannot finish any meal -- I'm just not hungry. So maybe that's not helping things.
Re: am I exercising too much?
the first Tri you are going to be dead tired all the time. I would grab my ipod, put on my sports bra and tennis shoes...and DH would find me on the couch sound asleep when he got home.
your energy will go right back up in the 2nd tri. As for working out, you can keep doing what you were doing before as long as it is comfortable. There are certain exercises that you need to modify or eliminate as you get later into your pregnancy, but for runners your body will tell you when it is time to trade your run for a walk.
I worked out (im not a runner, im a crossfitter) up until my due date then didnt work out at all for the week i was overdue due to blood pressure issues. But the docs said my working out all 40 weeks helped speed my recovery afterward, so keep on runnin!
