He said the Rotorua Marathon was marked down as one of the tougher marathons but "there's only one in the world where you can run around a lake start to finish and has been run 53 years consecutively, except for 1999 when it was washed out".
Registration starts on Friday from 2pm at the Energy Events Centre, where the start and finish line are located, and people could also check out a variety of trade stalls set up.
Lake City Athletics Club captain Phil Gulbransen, who will be running the half marathon, said about 85 club members would be taking part.
Most have completed the club's 16-week marathon clinic where people build up slowly to take on the full distance.
"Everyone seems to be really excited about it. They have spent a lot of time getting ready for it.
"We cater for everyone and all distances, depending on what they want to achieve."
Rotorua Association of Motels chairman Mike Gallagher said his two motels were very busy with most other motels also full or close to having no vacancies.
"Normally marathon weekend is really busy, but the rest of May has dropped off with forward bookings not as good as last year.
"Certainly, the sports events, and all those other events, up to the start of May has helped stretch out the season. Now for us moteliers it does quieten off, but we do have a busier period for the week around the Lions tour," he said.
On Friday 2174 school children from around the region will finish the final 2km of their 42km Rotorua Mini Marathon they have been completing over the year.
Otonga Rd School sports co-ordinator Neil Carrington said 481 students from his school were taking part.
"They've done it as part of their school fitness programme by running a 2km loop around the school.
"It's all been a bit of fun and have been doing it for a few years now."
