Noob here. I got started w/ triathlon 3 years ago. I completed my first 70.3 (Redman) at the end of last year. Decided I was ready to give IMTX a shot. (Living in central Ark, it was close for me as well.)
Also, like you, I have a young family. The window of having time to train gets smaller by the day… My second child was born last Nov. My son was two then. It only gets harder to find time to train as they get older.
I set up a pain cave in my garage. 80% of my training was done on the treadmill or bike trainer watching kids movies with my toddler and putting my infant daughter to sleep with the hum of the machine I was on. The truth is, even w/ two kids, as long as their small (under 3) 90% of what they need can be right in your house. So I set up garage so I could do everything but swim right there anytime I had a spare hour, or half hour, or whatever. There’s time there if you can take advantage of it.
Now that my son’s 3 and daughter is 1, I can’t see how I could have legitimate time to train w/o quitting my job, ditching them with my wife all the time, or going broke on babysitters. Plus, it’s kinda of fun to be around them.
I don’t regret my decision to move forward and do an IM this year. Your SO needs to be 100% on board. And you’ve gotta, for the most part, give up everything but your job and family. That’s why IMTX worked for me. We stay close to home during the first four months or so of the year. From Memorial day through New years, it feels like we’re gone every other weekend.
IMTX is hot. But it’s a great race. Really well supported and well run. (You can search ST for my race report, if you’re so inclined.) So, just slow down, take in lots of salts and fluids, and enjoy the day.
Sorry to be so disjointed w/ my response. In short, IMTX is great (and hot, but so what). It will only get harder to train moving forward w/ your family. If your SO is with you, do it. You won’t regret it.
