I can see how those of us, like me, who aren't that good at any other stroke might want to do this. But boy are they different events. The 200 is a real lung-busting endurance race (for a 200) while the 50 is a pure muscle sprint. It's almost like they are different strokes. It might be a little hard to switch gears between the three of events, but I'm sure it can be done. How to train for it? I don't really know. Swim a lot of breaststroke and have days where you practice the 200 and days where you practice sprinting, I'd guess.
