The Chatfield Classic will consist of a 1 mile swim followed by a 2 mile swim.  In between the two races, there will be a short break to allow people to warm up, warm down and rest.  Particpants who have not swam at the Chatfield gravel pond in the past should be aware that there is a gravel bar in the middle of the lake.  The gravel bar can create some shallow and slightly technical swimming, and also adds some race character.
