FLOW Stormwater Run-off 5K
The event takes place on October 4, 2026 at Liberty Park in Powell, Ohio. It is the inaugural Stormwater Runoff 5K organized by Friends of the Lower Olentangy Watershed (FLOW). The course runs through Liberty Park and highlights stormwater management practices that reduce flooding and erosion, allow water to soak into the ground, or divert runoff safely into streams and creeks that feed the Olentangy River.
Registered participants receive a race t-shirt, with sizes not guaranteed after September 15, and a swag bag that includes sponsor items and a native seed packet.
Distances:
- 5K
- 1.5 Mile Fun Run/Walk
Registration opens July 1, 2026 and closes August 31, 2026. Registration fees are $30 for the 5K and $15 for the 1.5 mile event.
October 1–7 is Stormwater Awareness Week in Ohio, an educational effort about how stormwater pollution affects land, water, and farms and steps to prevent it.
All proceeds benefit Friends of the Lower Olentangy Watershed, a volunteer based 501(c)(3) established in 1997. FLOW’s activities include tree plantings, invasive species removal, stream water quality monitoring by citizen scientists, pollinator garden maintenance, litter cleanups (481 tires recycled and over 6,000 pounds of trash removed in 2025), and three volunteer run tree nurseries growing over 2,500 native trees and bushes.
