I'm not saying any of this stuff really effects me I just found it interesting.
Length of my hair:
XC: My top 3 races all happend within 2 weeks of getting my hair cut. I got my hair cut twice this season. The longest my hair was all season was districts and that was also my worse race.
Track: I started the season with basically no hair (swimming) and my season started great. I leveled out in the middle of the season and then judging by photos cut my hair and got two prs within the next 2 weeks.
New Shoes:
XC- Over then summer I ran a 9 mile run on a mountain (xc camp) in under a hour. This was the first time I ran in those shoes (stupid idea but it made me run fast).
XC2- First time I wore my new spikes I ran a grass pr.
Track- I didn't get any new shoes during the season. I used my old xc spikes for track. My training shoes already had a few runs in them before the season started but they were run that all I was doing was testing out my injuried leg so they weren't fast.
I have a few more but I have to go.
