Same format at Choo 70.3. They do have folks with signs that attempt to seed you, but I know there were people who thought getting in the front of the line (even though they swim 2:50/100........and I'm not kidding) was a good strategy (even though your time doesn't start until you cross the mat and jump in).

I seeded myself in the correct place in line.......and had an OK swim (very little contact).

Good luck.

**Edit....we jumped off the dock in 2 steady lines.
