if it makes you feel any better:
completely knackered after cooking all day, upon returning home I decided I'd get a few cheeky runs in. Got on the bike and nothing felt right, climbed up a nice rooty roll in that I've done a few times now, sat at the top gazing into the middle distance and not "feeling it" at all, started to roll felt like my feet were on backwards and then lost a foot and fell over my bike into a few nice and fresh nettles! then tried to ride down some steps that I've never ever had a problem with to almost the same result! mincing like a gay kitten devoid of any gnar! I need more sleep!!! (and skillage) feel like a right (brused and sore)numpty!
