Chatfield Classic

August 13, 2017

Chatfield Reservoir, Littleton


4th Race in the Mountain Swim Series


This is a new event for 2017.  It 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.  Participants 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.

Participants may sign up for either the 1 mile swim, 2 mile swim or both.  It will be the last event of the year for the Swim Series and overall series winners will be announced at this event.  It is also a good training swim for the Horsetooth Open Water Swim, which will be held on Sept. 10, 2017 approximately 1 month later.  We hope to see you in the water!!!
