I think if you are training for only the 50, you are also " training" for the 100.
That's true. Raw speed definitely helps the 100. So does working on technical aspects of the swim (eg, starts, turns, breakouts).
Can you really just train for the 50 without training for the 100?
Sort of. I think that training for the 50 carries over to the 100, but lactate tolerance is more important in the latter. If ALL you do is speed-work, and very few (or no) lactate tolerance sets, then your 50 will be significantly better than your 100. Just my opinion, of course.
