#1 It was an AH high school fic and Buffy and/or Spike were on the running team. I think it might have been a WIP.
yup...read this one a while ago. :
How soon is now? by Riahannonhttp://spikeluver.com/SpuffyRealm/viewstory.php?sid=18481At a loss at what to do with his daughter, Hank Summers sends Buffy to live with her mother in the small town of Sunnydale away from any trouble. There, Buffy struggles to forget her past, meet new friends and start over. And who just happens to be the boy in the bedroom next door?----it's not completed, so this might be the one you're looking for... the actual Spike and Buffy running together is in chapter 9 called -race you-.

hope this helped and it's not too late
