I see it this way:
You spend a lot of time training (I assume, unless you are genetically gifted) for race day. This sport means a lot to you (again, I assume), yet Trek has never been largely committed to the tri market. They put out a model for a year or two (think Hilo) and pull out. Hop in, hop out. There are other bike builders who are more vested in the sport--and you as an athlete than Trek. IMnsHO, Trek tri-bikes reflect their attitude towards the sport--tertiary at best.
Supporting the LBS is good, but if you’ve purchased a few of those road bikes from them, they should survive the season without selling you an Equinox.
