On the road again

I ran my favorite neighborhood run at a tidy pace last night. It felt great. Nice to have fresh legs, even if I was kind of spazztastic and off my rhythm, but as long as I'm still in shape, that will come back. I'm still totally torn about what to do on Sunday. I'm really anti walking in races. Even in my worst tri I managed to shuffle my feet just enough to feel like I was trying. I'm just not sure I have six miles of running in my legs quite yet. I have more soreness this morning from last night's quick and easy run. I know 100% I could probably go out there and run a PR 10k but at what expense to the long road of building my mileage back for marathon training?
