All races will begin with an in-water start and finish onshore. The course is a 1-mile rectangle and
will be swum in a clockwise direction. One time around the course will constitute the one mile events. Three circuits
around the course will constitute the 5 K. Course map is available at the following link:

The National Championship 1 mile will be swum first, followed by a non-championship 1-mile for OEVT (single day
registrants) and those using Category II swimwear. See USMS Rule 303.7 http://www.usms.org/rules/part3.pdf for
description of Category I and II swimwear. Those who enter after the maximum number of entries has been met for the
National Championship may swim the non-championship 1-mile instead, if that entry limit has not yet been met. The 5K
swim will begin one hour following the finish of all one mile swims with swimmers with Category I swimwear first (USMS
members and OEVT), followed by those with Category II swimwear. Category I and II maybe combined in the 5K
depending on the number of entries. Swimmers will be seeded by 1500 meter or 1650 yard times, seeded fast to slow.
Seeding will be by waves with maximum of 50 swimmers per wave. The course will be cleared of swimmers before the
next event begins. Seed times are required. NT entries will not be accepted.
