Note to self: after a hilly century the previous day, and a light-to-moderate-intensity 35-miler in the late morning, do not plan to haul one's 42-pound child in a 20-pound trailer behind one's fully-loaded 45-pound commuter under one's fat-arse 200+ pounds up McClure Ave without feeling it in one's knees just a wee frickin' bit.
