He challenged Rotorua to beat Tauranga's entry numbers.
Alton said people were encouraged to dress up in any Christmas costumes, not just as Santa, and he already knew someone going as the Grinch.
Megan Kusabs, Graeme Dingle Foundation regional manager for Rotorua, said the foundation was grateful to be supported by the fundraiser.
Kusabs said the Graeme Dingle Foundation provided a range of personal development programmes for children and young people, including Kiwi Can for primary and intermediate age pupils.
There are currently three Kiwi Can schools in Rotorua - Horohoro School, Sunset Primary School and Kaitao Intermediate.
"We would like to be expanding and to take on more schools going forward, to support the young people in our community."
Each adult entrant receives a free Santa suit as part of the entry fee and children get a hat.
The courses are kept easy.
