24 hour racing is one of the best ways to start racing, since it is more of a relaxed atmosphere.

some tips - pre-ride the course to figure out what your times are, then you can plan to be at the transition area on time....
plan your eating well - the fatigure and excitement can put tummy on edge. So eat what you love, and yes it might mean some simple carbs. for me i eat powdered donuts (mmmmm donuts), fig newtons, chips, plain pasta and perogies for most of my 24 hour racing. no fruits, period. i told that to a team mate, and she ended up barfing up her cantelope during her lap because she thought she would be fine. everyone teased me about my pepto bismol and everyone else used it 'cept me!
clothing - it can get cool at night, and weather is unpredictable so bring it all!

i pre-bag my bike clothing, so that i don't have to think about it too much (ie one short one jersey, sports bra and socks in each bag).

DO NOT LEAVE THINGS un covered over night, the morning dew gets on everything! i have laughed seeing teams hang everything "just so" when they set up camp, only to have it all soaked my morning.

practice your night riding

i'll think of more later, time for the AM coffee

Smile!
