I've heard over and over - listen to your body, some days will be harder than others. I heard my body loud and clear this morning, and just a half-mile into my planned 5.25 miles. There was the piercing ache in my right side, my shins making themselves known and my breath escaping my lungs but not returning. I know, sounds like I'm overreacting in massive proportions. Maybe I am.
Maybe my muscles are still recovering from my Pilates class yesterday? Though I always go to Pilates on Fridays before my Saturday runs.
Maybe I didn't drink enough water yesterday? I'm sure last night's salty homemade popcorn didn't help.
Maybe it was just a bad day.
I ran/walked my way home, not evening breaking the one mile mark. I'm going to stretch, drink a few gallons (exaggeration) of water and try again tomorrow.
