Share 'Doing a race at the end of week 9 of competitive season'

Hello Mike, I'm following your 36-week program to do my first half ironman on august, 23. In week 9 of comp. season of the program (july, 19), there's a 2k swim/60k bike/15k run race I really would like to do. Is it smart to do that race? If so, how should I change the workouts of that week to deal with the sunday race? By the way, I really love the program, I love the way everything is written…
