Maple Ridge Run - Monday, May 28, 2018- Owasso Island, 25th & Owasso, Tulsa, Oklahoma

The Maple Ridge Run is one of the longest running (pun intended) 5K races in the Tulsa area. It is one of the few races in the US that takes place entirely within a single neighborhood. Maple Ridge Neighbors are pleased to support this Memorial Day event for the past 32 years and look forward to many more.

The Maple Ridge 5K and Fun Run share a course through the beautiful and historic neighborhood located in mid-town Tulsa, Oklahoma. The 5K course is two loops through the hills and meandering streets of the Maple Ridge Neighborhood. Whether you are racing for a personal record or out for a leisurely walk with your neighbors you will enjoy the manicured lawns and historic homes throughout the area.
