The Importance of Concentration in Races

I feel like the concentration of trying to stay on someone's feet is actually quite difficult, which is why you kind of touch their feet. And even if they swim a couple meters extra, it behooves you to probably stay with them. I've just never had- It's crazy. This happens at the front of races for age groupers and for professionals. Obviously, you guys professionals, you're all very fast. But I've never been able to swim with someone in a race.
