It's Not About Swimming More
We have all been there as triathletes. You're a good bike / run athlete, and you came from another sport at which you excelled. During your WHOLE life athletics have offered you a simple equation: put in the time and get the reward.
Except it's not working with your swim.
You've watched a million YouTube videos (stop doing that). You've read books and performed drill after drill during your sessions. You've abandoned drills, exasperated, and just decided that you'll get faster through more training volume. Except that doesn't work either, and now your shoulders are injured.
You're especially tired of going to the pool and getting lapped by the 10 year-olds at swim practice next to you.
Are you thinking about abandoning swimming altogether, since it seems that no matter what you do you never get any better? Are you (gulp) considering becoming a duathlete?
WHAT IS GOING WRONG?
Forgive us a short digression, but one thing we always tell athletes is that swimming is far more like golf than other endurance sports. Golf is almost all technique (although you should really try playing 18 holes before you say there isn't any endurance component to it), and golfers hone their skills through long, deliberate practice.
Any of you catch the crucial word in there?
Yeah, "deliberate." Most triathletes haven't been taught correct technique in the pool, so they resort to what they know best: slogging through hundreds of hours of pool time, hoping that simply by swimming more they will improve. We'd ask you to think about the golf analogy again, and maybe you've gone to a driving range before and experienced the unique frustration of hitting a ball badly again and again and again.
Do you think you'll become better at a skill by repeating a bad swing 1000 times? A million times?
Because that is precisely what you are doing in the pool if you don't know correct technique. You are simply repeating bad habits over and over.
That's right: your swim sessions may be making you a worse swimmer, not a better swimmer.
