Ride your ride, folks. Don't be uptight about switching things around as you get fatigued. Everyone does it.

Breathe in.... repeat after me: whatever feels best when I ride is best.... breathe out.... breathe in.... repeat after me: I don't have to get uptight about studies and techniques... breathe out.... breathe in.... repeat after me: I don't have to compare myself to everyone else.... breathe out.... breathe in.... repeat after me: I'm ok, you're ok.... breathe out.... breathe in... repeat after me: all bikes are beautiful, and so are all riders, I don't need to feel insecure about my bike or my technique... breathe out
