Get ready for a brand-new summer running tradition in Saint Louis! The Summer Sizzle Series offers four Thursday night races across different parks throughout the season—a 2-mile run in June, a 4K in July, a 4-mile run later in July, and a 5K in August—with flexible participation (complete just 3 of 4 races to earn a finisher medal and exclusive series shirt). Each event features a 1-mile fun run option, post-race socializing, and music, making it the perfect midweek excuse to get outside with friends and stay motivated all summer long.
