For Dopey, especially!!
2 pairs of running sneakers.
Bring throwaway layer clothing- I usually get mine from walmart..sweatshirts are around 12 bucks and sweatpants about 9. Some of those mornings are downright cold
Temper your expectations for parks. 4 early mornings will zap you more than the races
After each race, get in that hot tub/pool and bicycle your legs around- huge help!
That big hot tub at Copper Creek was a godsend during a cold Princess Weekend.
