Weiss typically comes out of the water behind his competition and rides straight through the field. He has a tendency to get too jumpy, however, during the first half of the race. To control his effort, Weiss consults his SRM power meter to look at his average power. Weiss says he, “always trains with watts and I really have to check my average watts during the first hour because I have to slow myself down. Otherwise I would have too much adrenaline and motivation coming from the swim and I would go too hard.”
