Head to Cleveland's Greenway Park on Friday evenings in late May, June, and July for Terra Running Company's 5th Annual Summer Sizzler 5k + 1 Mile series—a celebration featuring chip-timed, flat 5k races alongside a family-friendly 1-mile fun run, complete with lawn games, music, and surprises. Every participant earns race swag at each event, and runners who complete all three 5ks receive custom Summer Sizzler socks as a bonus. Registration is $25 for the 5k and $15 for the 1-mile (with early-bird pricing through March 31, 2026), or save 10% by signing up for all three 5ks together.
