Harvey Mills Longest Day 10K returns to Brookings, South Dakota on June 20th for its annual event. This run takes place in the Southern part of town along partially shaded bike paths and through neighborhoods that offer a mix of urban charm and natural beauty.
The race starts early at 7am under clear skies typical of late spring or early summer in this region. Participants will experience a firm but slightly soft surface, which can make for an interesting run. The UV index is expected to be very high on the day, so sun protection will be essential. Runners are advised to wear light, breathable clothing and perhaps consider a hat.
This event has been running since 2014 and has grown in popularity over the years, drawing participants from not just Brookings but also neighboring towns. The race supports the Harvey Mills scholarship fund, which helps local students further their education. This makes it more than just a run; it’s an opportunity to contribute positively to your community.
The course is a scenic out-and-back 10K that loops through the city, offering runners a chance to enjoy both urban and natural surroundings. The route includes several notable features such as tree-lined bike paths which provide welcome shade during warmer parts of the day.
At the start line, you will find familiar faces from previous years; some have even signed up for the 10K relay option, where teams can split their run time over multiple participants. Aid stations are set at strategic points along the course to ensure runners stay hydrated and energized throughout the race.
Weather on June mornings in Brookings is usually mild with temperatures ranging between 65°F to 75°F (about 18°C to 24°C). The UV index of Very High will mean strong sun exposure, so it’s important to apply sunscreen before heading out. A light breeze can help keep things cooler but be prepared for the possibility of a hot and sunny day.
