Treadmill Laziness

Would you believe I've spent the whole day wondering whether I'm too sick to go for my 6k run tonight? I am a complete wuss! I know I can do it, but I'm just feeling to lazy and scared to run more than 5.4k! Aaaaargh, God grant me strength! (In my defence, my nose has really been a cross between being stuffed and runny, so it's not as if I'm a 100% illness-free!)
