Depends, are you a FOP swimmer"? True, you won't win/lose the race, but I disagree with jmk above a little bit. If you can get out quickly and be in the first few people at the first buoy, you'll have a much cleaner swim. Anyway, my tips, almost all my tris are running beach starts
Seed yourself front to back. If you are FOP, go to the front row. BOP, hang out in back. Self explanatory.
Seed yourself left to right. Get in the water
(or ask the guards, or watch prior waves
) to see which way the current is going, if any. Sucks to have to swim back to a buoy the current has taken you past. Line up and enter the water UP current of the buoy.
Walk the entry before the start. If you plan on running in, make sure there aren't any holes in the knee deep water. Stepping into one of those unexpectedly sucks.
Run to the water, high step with your knees until you can't clear your feet, dolphin dive until waist deep or so
(or when you can't effectively push off from the bottom anymore
), swim.
Coming in, check out behind you to see if any waves are coming. If they are, try to catch them. Whatever happens, keep swimming to shore.
When your hand touches the bottom, do a couple quick dolphin dives then run out
(opposite of going in
)
