With a sprint I'd say just take the day before off, and maybe a light run or ride two days before. IMO you really don't need much of a taper for the shorter events. Just make sure you eat really well, and I see your in GA, so be sure to drink a bit more gatorade in the days leading up to the race. Thats just to top off the electrolytes you'll need in the heat. Hydration is key in all events- no matter the length!
And ENJOY!!! Are you a mom? If so, what a great present to give to yourself!
Kick some butt and let us know how ya did!!
