Right on, Jeni! You'll love it -- and even if you don't (as IF!!) at least you gave it a try.
I wrote a paper for my pysch class last semester on how athletes stay focused during competition, what negative influences lessen performances, and how to overcome them. Basically, what it comes down to is being aware of all those factors that seek to bring you down, or just simply having "mental toughness". Concentration IS all that!!
Outside distractions do play a factor in breaking an athlete's concentration, so I tend to agree with Velogirl. Leave your cheering section at home (or stash them in a place where you can't hear them during the race) and tell them to not approach you beforehand. You'll be nervous enough!
So, I wish you good luck and "mental toughness". Oh and remember, speed rules.....and girl racers ROCK!!!
