2nd Annual Racing Underground
1.2 Mile & 2.4 Mile
Open Water Swim

Put this one on your calendars! Racing Underground will be hosting a long-course open water swim at the Boulder Reservoir on Saturday September 4th.

Swimmers can choose from 1.2 mile and 2.4 mile options. There will be a mass start at 6:30am, however the start line will be open until 7:00am for those swimmers who would rather not start with a group. Swimmers will have until 9:00am to complete their swim.

This swim can be as competitive or non-competitive as you'd like. All participants will be chip-timed (from their individual start to their individual finish), and results will be posted throughout the morning, as well as on our website on the afternoon of the event.

Food and music will follow the swim. Awards will not be presented for finish places - instead we will hold a sponsor merchandise drawing for everyone!

Registration for either distance is just $20 through August 15th and $25 thereafter, and includes chip timing, park entry, a safe course, good food, and a chance to win some great merchandise prizes. Click here for a print & mail entry form or click the button above for online registration.

COURSE: The swim course will be a large rectangle, which you will swim in a counter-clockwise direction. The course will be marked with large 5' diameter orange buoys. One lap of the course is 1.2 miles. You may swim 1 or 2 laps. You may switch your swim distance, however you do need to let us know that you have switched so we can list you correctly in the results. You will not come out of the water between laps - the 2.4 mile swim is a continuous swim. CLICK HERE FOR A COURSE MAP

Swim Course closes at 9:00am.
All swimmers must be out of the water by 9am.
No one will be allowed to start a second lap after 8:00am
