Thoughts?

I'm less than a week from my first half-marathon in over a year, having just gotten back to running in June after a year hiatus.  I've also been knocked flat the past three weeks with a lingering sinus/headache thing, and just when I was feeling better, a fever and sore throat.  My questions are thus:

1.  Did I take on too much too soon, setting myself up for this?  Let's say I started at 10-12 miles a week, and hovered around 20 most of the summer (though I hit thirty once).  I was also lifting and swimming, but not super-reliably, and not since the school year started.

2.  Should I still run the half on the 10th?  I'm pretty sure I'll feel better by then, but will have lost a month of training and will be recovering from various illnesses.  But, if I can knock it down to the 10K, at least I won't have to DNF, right?

So send positive vibes my way...the clinic didn't think it was strep, but we won't know until tomorrow.  In the meantime, I'm taking lots of fever reducers and cuddling with the kitten.  No running for me, thanks!


P.S.  Finally got my Garmin!  Have not yet used it except as a costume detail for Spirit Week at school...
