You know, I've heard a few people say, "this is only masters, it's no big deal."
Yet, as I meet more people I learn about stories of people enjoying the sport, and the years of dedication they've given to swimming. 60+ years old, still healthy, still strong, going 32 for 50 fly... ???!!
Being fast at 20, great, way to go.... Try a lifetime of dedication, that's even greater.
