Doona Days

I've been enjoying the warmth of the doona for the last 2 mornings, and it's been sooo nice! I know I could get up and walk for an hour, expecially now that the cold snap appears to be over (for the moment), but what I really want to do is run - but if I run fairly hard on Monday nights, should I also run (gently) on Monday and Tuesday mornings? Is that overkill?

My left hip is a bit achy this morning, so I'll rest it until tomorrow night (that's my excuse, anyway). But I've been enjoying the morning runs and don't really want to give them up when I start running 3 nights a week again.
