I mostly practiced front crawl in the 25-meter pool, which was often emptier and so required less awareness of what was in front of you. The 50-meter pool has dedicated lanes for "fast front crawlers", where people move around in a long-stretched rectangle. But I didn't dare to use it yet – think I'm still slower than when using breast stroke.
But by now, I *did* manage to front crawl a full 50-meter lane a couple of times, which felt great!
