Need Some Advice

Plenty of people have gone into their first (or subsequent) HIMs underprepared (to varying degrees of success in finishing), but since you don't log your workouts, there's really no way to tell what "very little" means.

Three months prior to HIM (when you started the job) is peak training time. I assume you've been following some kind of a plan, and if you haven't been able to do most of the workouts, especially for your first HIM, it would be folly to do the race.

Can you safely complete the swim/bike/run? 

Will you enjoy the 56 mile bike ride, followed by the 13.1 mile run? 

If the answer to either of these is "NO," the smart thing would be to DNS (Did Not Start).  You might convince the RD to defer your registration for a year, but more likely not.  The RD isn't responsible for you starting a new job that takes away from training for a HIM. 

Most people are getting fairly close to tapering in thier programs, you have not even started a training program. Life sometimes gets in the way, we can all relate, but you sighned up 8/4,?????????????

Don't enter, you could get hurt or worse! Judging by lack of logging, your previous posts, and no comitted program, you dont have the conditioning for this distance race. Try to get a deferment on your entry fee, and don't say work got in the way, that would be a surefire rejection. Think about your signature line.
