I know. I'm a beginner and the most obvious answer is that I just need to work on my endurance and practice. But I can swim breaststroke (my best stroke) seemingly forever without feeling the exhaustion I do after sprinting a 50 free or even slowly swimming a 100 free. I swim on my own (not with a club), but did join a group workout on Tuesday. The instructor was pleased with how my freestyle looked, so I don't think I am doing anything horribly wrong. I do think I have a weak flutter kick. All in all I do think I am going to be a sprinter, but I would still like to be able to do a slow freestyle during a workout and go farther than 100 yards. Tips?
