About the Circle the Lake Half Marathon
The Circle Lake Association puts this September race on as a fundraiser, with proceeds paying for aerators and habitat work on the lake. It lands about two weeks before the Twin Cities Marathon, which makes it a natural final long tune-up for that field.
Course
The loop starts and ends at the old Millersburg schoolhouse and rolls through farm country on a mix of paved and dirt roads. The hills are steady rather than steep, but they accumulate, so treat it as an honest rolling course rather than a PR setup.
Race-day weather
Mid-September in southern Minnesota often starts in the 50s and warms toward 70. Much of the loop is exposed farm road, so sun and a light crosswind usually matter more than heat.
