All proceeds will benefit the Zelienople Rotary Club and the Zelienople-Harmony Area Chamber of Commerce. The Half Marathon will be a very tough course. The Half Marathon is a very tough course. The 5K is rolling hills and the 1 mile is flat. Overall, this will be a great race for anyone training for the Pittsburgh Marathon.
