When I bike commute to work, I normally drop my bike off at my desk, switch my cycling cleats for normal shoes, and then head to the locker room to shower (cycling cleats really suck to walk in). I have a weird work schedule today, and I locked my bike up outside by the locker rooms, and went to my desk after showering. The only shoes I had in my locker to put on to walk to my desk were my running shoes.
Unfortunately, I forgot to change out of them before heading to the airport to catch a flight. At least this is a pretty low-level meeting today! (I also wish I had remembered gloves – it’s going to be 15f/-10C in Birmingham Alabama when I land, and I need to spend some time walking around the airport ramp)
