With the 50th Rotorua Marathon quickly approaching, it is fair to say the marathon has become something of an icon in the geyser city.
The Rotorua Marathon is well-known in New Zealand for being one of the oldest and most beautiful marathons in the country.
Held in May, the marathon does a full circle of Lake Rotorua and attracts thousands of participants. It is not only for runners but attracts walkers and joggers who want to give it a go.
The marathon started in 1965 and has only been cancelled once, in 1999, due to flooding.
Colin Smyth has finished every marathon but he wasn't the only Rotorua runner to have finished that first one.
