Serious and recreational athletes will circle Hamilton's Lake Rotoroa on Sunday.
Participants can register on the day and select a distance - walking or running four, eight or 12km in either a 16 and under or adult classification.
The Hamilton Road Runners' Hamilton Lake Fun Run and Walk starts at 8am with the 12km walk. All other distances, which leave from the Hamilton Yacht Club, start at 8.30am.
The Hamilton event is the last in a series of three in a summer series. Hamilton Marathon Clinic ran the Blueberry Run on February 10 and Te Awamutu Marathon Clinic organised the Kakepuku Run on February 24.
People who take part in all three events qualify for the lucky draw to find the winner of a $1500 travel voucher.
