Circle the Lake Half Marathon, 10K, and 5K

A Race with a Purpose: Fun, family-friendly, dog-friendly a race with a purpose as all proceeds help improve our lake water quality. Last year we raised over $32,000 which went directly towards 3 new aerators for the lake to reduce invasive weeds/algae, and promote a healthy fish habitat.

Marked by beautiful views and a country feel, the Circle the Lake Half Marathon, 10k, and 5k will take you along the shores of Circle Lake in rural Rice County, MN. Located just 20 minutes south of Burnsville, MN, these courses are run over rolling hills on a mix of paved and dirt roads.  It is possible to spot bald eagles, osprey, deer, ducks, pelicans, and to hear the hum of a distant tractor.  Runners will have views of the island in Circle Lake, home to many species of wildlife.  These courses are open to competitive racers, families, dogs, kids, seniors, and are Ear Bud friendly.   We start and end at the historic Millersburg School House and you will follow the same route the Jesse James Gang once traveled.  

 The Half Marathon is held two weeks before the Twins Cities Marathon, making it perfect for those of you training for that race.  Our half marathon is tough and will test your mettle. There are several big hills that will challenge you!  All races will be chip-timed. There will be posted mile markers and water/sports drinks will be available throughout the course.

 All racers registered prior to August 23rd will get a commemorative t-shirt. We cannot guarantee a t-shirt for registrations posted after that date.  Medals will be awarded to all finishers.  We will also have a prize for the male and female winners of each race.

There is a $10 price increase on August 23rd.  Register early to assure your spot and save some money.  Same-day registrations will be available.  Races are rain or shine and we cannot offer refunds or transfers to another person.

 Invite your family and friends to cheer you on and celebrate your accomplishment at the Boonies Grill, located at the start/end of the race.  Boonies is pleased to offer you one complimentary drink after you finish.

Same Day Registration runs from 7:15-8:15 A.M. The 10k and Half Marathon races begin at 8:30 A.M. The 5k race begins at 8:35 A.M.

Circle Lake is used for recreation, sports, and by naturalists.  This is a charity event sponsored by the Circle Lake Association. www.circlelake.org  The association has many projects completed and much more planned to improve the lake's watershed.  The proceeds from this event go toward funding those projects.
