Benefit of a bike fit-Best $150 I've ever spent on this sport

I've had my bike for a year and a half now, and just recently had a professional fit. I thought it was fine, I was comfortable, no real pain issues, could ride 4+ hours without any problems, but I am doing my second ironman and felt it was at least worth looking into. I looked around at the local shops and the prices ranged from $250-$400. Then when asking for recommendations a local coach, mentioned that he does them at his home for $150. I talked to him briefly and decided to go that route. Also told me that he'd cut the price if he didn't have to do much, so that sounded like a deal.

I've done two rides since the fit and oh my god, the difference is amazing. My first ride was an 80 miler along a course I've done a ton and like clockwork I'm typically at 18 mph give or take. This ride, same effort level I was at 19.3(dropped a bit at the end doing some hills to get to 80 miles). I was more comfortable than before, and significantly faster. Not only was i faster, but I was faster for a longer distance than I've gone before. My longest ride prior to this one was 78 miles, pretty much the same route where I averaged 18.2.

I always under rated the value of a bike fit, figured I was comfortable and there are way more "fun" things to spend money on in triathlon. But, what I'm saying is if you've never been fit and even if you think you're good, it's well worth looking at. I'd have never known I could be so much faster and more comfortable.

By the way, the fit was done by Heath Dotson out of Asheville, so if you're in the area for whatever reason, I HIGHLY recommend him if you're need a fit. Did a great job and really looked at everything very closely.
