The 20 Miler Relay Race is a team canoe relay covering 20 miles of river in two sections with a mid-race team exchange. Teams of up to four paddlers pair up to paddle each section using Headwaters-provided canoes; lifejackets must be worn for the entire race. The event includes transportation to and from the river if needed, a race-day t-shirt, an after party and awards ceremony with trophies for the top three teams and a prize for best team costume.
