The key component of my training that is essential to be successful in open water at the elite level is changing your speed. I think that's a common misconception at the age group level; it's really tough to get faster if you just practice at one consistent speed. Sure, that might get you in decent aerobic shape, but you have to be able to separate yourself from the pack in a race or respond to moves being made by other competitors. I might be a "distance" swimmer, but in some form or another I will be working on my sprint freestyle in every workout as well.
Example of main set (long course meters):
8x50 free on :50 seconds (hold :30 sec per 50)
200 free cruise on 3:00
4x100 free on 1:30 (negative split the 100)
200 free cruise on 3:00
2x200 free on 2:45 (negative split the 200)
200 free cruise on 3:00
400 free for time on 6:00 (went about 4:14)
200 free cruise on 3:00
Total of 2400 meters
