Organisers are hoping to double the number this year.
Dennis de Monchy, a member of the Tauranga off-road runners group, is helping organise the Santa run.
Mr de Monchy said the event was open to all ages as long as participants wore a santa or Christmas-themed suit.
"People can embellish their suits and costumes as much as they like.
"Last year we didn't only have Santas but elves, reindeer, Mrs Clauses, and I think we even had a couple of lovely angels. It's brilliant family fun and it's all for a great cause," he said.
Mr de Monchy said participants could run, walk, skip or hop - finishing the course however they liked.
Prizes will be awarded for the fastest male, female and child, the best dressed adult and child santas and the best all-round corporate team.
Mr de Monchy expected competition for the fastest santa title to be fierce, with some very fast santas headed to Tauranga.
Every $28 adult entry fee entitles the entrant to a free Santa suit, complete with hat and beard, to be collected from the registration stand on event day.
The $10 fee for children does not include a Santa suit.
KidsCan chief executive Julie Chapman said the event was a fun way to get into the Christmas spirit with friends, family or work colleagues, whilst raising funds for a great cause.
