TAPER ???

I AM TRAINING FOR A 70.3 IN SEPTEMBER...MY QUESTION IS I AM USING 2 SPRINTS AND 2 OLYMPIC TRIATHLONS BETWEEN LAST WEEK AND THAT RACE AS TRAINING...SINCE THESE RACES ARE BEING USED AS TRAINING SHOULD I STILL TAPER THE WEEK BEFORE THESE TRAINING RACES ??? IF I TAPER I AM LOSING TRAINING TIME FOR THE 70.3
