Athletics New Zealand Events Manager Gareth Archer, is excited by the big number of overseas visitors coming to Rotorua for the marathon.

"Rotorua is an iconic marathon with a unique course. It's also the oldest major marathon in Oceania, in a city renowned for its thermal wonders and scenic beauty so it's not surprising that we attract many international visitors to Rotorua for the race each year," Archer said.

Rotorua Marathon is on Saturday April 30. The half marathon starts at 8am and the full marathon is under way at 8:20am, both from the Rotorua Energy Events Centre.
