It is public event for runners of all ages, the Butterfly Run has a distance for everyone. Participants select a level of participation—they can choose the 5K, the 10K, the family fun run & walk, or even pick one of two other options—run on your own time “virtually,” or you can sleep-in and forgo the running all together. Regardless of your preference, every mile completed and every dollar raised means thousands of East Tennessee children receive the health care they need.
