It depends on the person, but for a sprint, the taper is usually the week of the event. Maybe a week and a half for an oly. For my first sprint tri, this was the plan my coach gave me. I have used basically the same plan for every race since. It works well.

Sunday BRICK 90 min Bike/ 30 min Run
Monday 45 min Run
Tuesday 45 min Bike
Wednesday 30 min swim
Thursday Rest
Friday Rest
Saturday Race
Sunday Rest


Good Luck
