A few things I learned at my first national race.

The guys are a lot stronger in the national expert class than Michigan expert class.
Short track is ruthless! Fast, shoulder rubbing and you need a really good warm-up
Super “D” is crazy fun! but you need some pads if you fall, a little more travel and stronger wheels.
When you fall you body hurts!
Rocks get stuck in helmet vents.
XC - the course was though! 70% climbing, over 800’ in the first 3 miles the decents were just as hard! No rest period!
Naked crits are funny!

Over all, the weekend was great!
