Running plan for the week...

Tues 4.5mi
Weds intervals (8x400)
Thurs 3mi
Fri rest
Sat 4mi
Sun 9mi

Following a Hal Higdon plan this time... we'll see how it goes. It seems there are no hills in his plan, though, and I'm running a hilly 12k and a hilly-ish HM. Maybe I should substitute some of my interval days with hill days, or trade off? Tuesdays trade off between tempo runs and intervals, maybe I should run some hills in my tempo run or just substitute hills entirely for intervals or something. Hmm.... mix and match?
