Swim
On race day, arrive an hour early to set up your transition area. Put your bike, shoes, and helmet in a place that's easy to get to. Set a towel on the ground so you can dry your feet before putting on your bike shoes. "Start at the back of the swim field if you're uncomfortable, and take your time," says DeBoom. The swim takes place in San Diego Bay, where water temps are around 65 degrees. Try to swim the course the week before.

Workout

Mon., Wed.
1,000 yds, in intervals (10x100 or 15x50 yds), at moderate intensity.

Sun. (race day)
.62 miles.

Bike
Get your bike tuned early in the week and ride it afterward. San Diego's race is a slightly hilly out-and-back ride from Spanish Landing Park to Cabrillo National Monument. On race day, Reed keeps his shoes clicked into his pedals so he can slide his feet in quickly. Whatever you choose to do, try it out beforehand. "It's never good to try something in a race for the first time, so if you want to go without socks or gloves on the bike, get used to it in training first," says DeBoom.

Workout

Tues.
60 mins at low intensity.

Sun.
19 miles.

Run
"On race day, think like a triathlete at all times, not a swimmer or a cyclist," says DeBoom. "You may be the strongest cyclist, but it won't do you any good if you go all out on the bike and are too tired to run afterward." The race-day course is a flat point-to-point along San Diego's Harbor Island and the Embarcadero – it's the perfect place to employ Reed's running technique. After the race, suck back plenty of fluids before that celebratory beer. Then enjoy. You've earned it.

Fri.
40 mins at low intensity.
