Onlookers could not help but notice the Jingle Bell Jog and Santa Walk.
First, there was the sound of bells ringing as the joggers made their way from the Trafalgar Centre to Tahunanui Beach.
Jogger Janae Grundy, decked out with 584 bells, took the prize for having the most ringing bells.
They were sewn on to her tiered skirt, threaded through her hair, tied on to her shoes and worn around her neck and wrists.
The jog is a family tradition for the Grundy clan with all eight members having joined in the event for the past five years.
Then there was a mass of red as the joggers dressed in festive costumes.
Nelson Events organiser Averil West said more people went to the effort of dressing up this year and got into the spirit of the event.
They included Phil Costley and son Oliver, 3, who took out the prize for the best dressed under 12.
The pair turned heads with Mr Costley dressed as Santa pushing Oliver the elf in a sleigh.
"Shouldn't it be the other way around?" others asked them.
"Maybe next year," said Mr Costley.
He and Oliver worked together on turning an old mountain buggy into the sleigh.
"He loved the whole thing," said Mr Costley, who is a teacher. "He had a great time making it and spending time together was cool."
The jog raised more than $400 for the Heart Foundation and prizes included bags of fruit and vegetables.
