You pull up outside your house and make your way to the front door at geisha speed;
You look at the height of the front doorstep and think to yourself "Who the hell put that step there?";
You retire to the couch with your water bottle. When the other half mildly enquires "What's for dinner?", you yell "Toast!, we are having toast for Sunday dinner and you're going to make it!";
You are certain that you must have been hit by a train, despite the fact there is no railway track within 20 miles;
You check your Garmin/phone thingy and realise you've run 20 AND A HALF miles, not 20 miles.
Ah well, by Tuesday I'll be ready to run again ๐
