Pain in left foot - uh oh, or okay??

RUN 6.2 miles in 60 mins. 2 mile WU, 2 mile at 9:05m/m race pace, 2 mile CD

Yet another treadmill run. I'd love to join the Thursday run group! But it was below 10F outside. Not warm enough yet. I got "my" treadmill for once. They're different, they really are. I play favorites.

Somewhere around mile 3-4 I felt a mild pain in my left food, under the 2nd or 3rd toe when I roll the foot to take-off. Was mild, didn't feel it much running.

My Race Pace is calculated to be 9:10 for a 1:59:59 half mary. So I ran 9:05 and it felt fine. That's the first time I've run that faster pace sustained, I've been doing songervals mostly.

As for the foot, it hurt a little more afterwards, and even now (the next day) I'm aware of it. It kept me up a bit last night, thinking about how February could be a no-go if this is really an injury. Stress fracture keeps coming to mind, but I've been running steady 3x a week for 2 months now, and I've been at this 12-18 mph for at least a month. So I haven't drastically increased, and I honestly don't feel like I've done the proverbial "too much".

So I wait to see what comes of it. I can feel it just jogging across an intersection :(  My planned runs for this weekend were are a 3 and a 6, I can bike those if needed -- the forecast is for the mid-60's!!!
