Kind of depends on the length of the race and your goals.  If it is a sprint or olympic distance, and it is not an A race, I would just take the day before off and then treat it as a hard brick workout.  If you're going for top performance, then taper the week before by reducing your volume and intensity by about 30%.  I usually take a rest day two days before the race (Friday in your case) and then do a short brick workout on the day before - 20 to 30 minutes easy on the bike with 3 or 4 x 30 second race pace accelerations, followed by 10 to 15 minutes easy running with 3 to 4 x 15 second race pace accelerations.  The idea is to remind your body what race pace feels like without exhausting yourself.  It also provides transition practice and a shakedown cruise for your race setup, if that's different then your training gear.

For a longer race the same basic theory applies, but you will want a little longer taper for 70.3 or Iron distance races.

Hope this helps.  Good luck and have fun on Sunday.

Hey Matt,

Have a great first race! I hope you'll fill us in afterwards & encourage a friend/family member to train along with you for the next one.

Enjoy!
