While I've been pregnant I've continued to run, albeit a significantly slower pace and less distance. I've been running 2-4 times a week, usually between 3 and 5 miles. My pace has gotten slower and slower. My pre-pregnant pace was around 9-10 minute mile. Today I hit an all time low:
4 miles at 11:54 pace. Ouch. Some people pogo-stick faster than that.
Last saturday I ran 5.1 miles at 10:47 pace, so I'm writing today off as a fluke- or maybe my Nike Plus was out of whack today.
