Similar to Cobie, I've been ill - just not too bad, but then again I was on vacation too bad timing.
Street:
I don't have any specific things, but I do have two scenarios: 1.) Commuting - 65 miles, one-way; although lately in the mornings I through on some extra stuff... sweat pants, rain jacket and pants, sweater, and some rain over gloves, which I love. After tucking the front coming home from work with only a helmet and gloves (had work shirt and slacks), I've learned 'it's better to sweat than to bleed' -- plus getting road rash debris'ed by a smartass reinforces the need for gearing-up; 2.) Riding the twisties with friends, which is a quick gear check, bike check, and go.
Track:
Nothing out of the ordinary. I make sure my bike is prep'ed, pack the night before, start hydrating (usually beginning the morning before going to the track), get plenty of sleep, have a couple bananas in the morning and try to get my mind right [pay attention to procedures, ride my own ride, etc.]. For me, my mental status is the driving force. For example: I did a weekend thing at Pahrump with Trackxperience, which was my first weekend experience. Had a blast the first day, a great BBQ at the track with them, but during the second day around 11 am, I couldn't hold a line or hit a turn-in / breaking point to save my life -- my mental status crapped out so I bailed out.
To be dreadfully honest, after leaving the Marine Infantry life (line corpsman, babe) I pretty much quit exercising, for which I'm now paying the price. One thing that I have come to enjoy and appreciate is the participation in bike forums. Not only here, but in the other bike forums as well. True, there's a bit more trash talking in a few forums (hehe ) but I think whether in jest or in guidance, the mere act of talking and reading about riding further solidifies skills, traits, ideas, thingies, do's-n-dont's, etc. Before my first time at a track, I'm readin and chatin... preparing myself for the tricky turns and those little tips from the guys who've been there. Knowledge is key, which is why I went to my first CSS class.... without the key, you can't unlock the life-altering fun, that is, riding.
