Resting is as hard as running

Tapering for this race has been tough. My knee is still exhibiting some soreness but I know I still have 3+ days of recovery prior to the half marathon. I wanted to get in one more run before Sunday but decided that protecting my injury is a far better strategy. I know that I shouldn't lose much conditioning after holding off from running for eight consecutive days but I'm struggling with the idea that I might. This lack of aerobic exercise is making me grouchy. I suppose it's better to have a negative response to rest than to embrace the sedentary lifestyle.
