Set against the backdrop of lush green hills and serene lakes, the Hillside Lakeside Marathon offers runners an unforgettable experience. This annual race is scheduled for September 18, 2026, providing participants with ideal fall weather conditions as they navigate through picturesque landscapes. The marathon route begins at the heart of Lakeview Park, where runners are greeted by a stunning panoramic view of the lake and surrounding hills. The initial kilometers take place on smooth asphalt paths that wind along the lakeshore, offering plenty of opportunities for scenic photography stops while still maintaining a comfortable pace. As participants move deeper into the race, they transition onto gravel trails that lead through dense forests filled with towering trees and vibrant undergrowth. These sections challenge runners' endurance as they climb gentle hills and navigate rocky paths, all while enjoying fresh air and natural beauty at its finest. The second half of the marathon sees a return to more open terrain, where runners can pick up their pace on well-maintained roads that lead back towards Lakeview Park. The final stretch offers an exhilarating downhill run through shaded streets lined with cheering spectators before crossing the finish line amidst a festive atmosphere in the park's central square. In addition to the marathon itself, there are also 10K and 5K options for runners looking to explore parts of this scenic route without committing to the full distance. Each participant will receive a commemorative medal upon completion, celebrating their achievement and the unique experience that is the Hillside Lakeside Marathon. The event not only attracts serious athletes but also welcomes recreational runners who appreciate the opportunity to enjoy some of nature's most beautiful scenery while engaging in athletic competition.
