To celebrate the jog, everyone taking part that purchases a ticket and turns up to watch the Blues take on Montpellier wearing their Santa outfit will be given a voucher to purchase half a chicken in the Nando's Brewery Quarter, Cardiff.
More than one and a half thousand people are expected to put on their Santa hats and help to raise £40,000 for the vital work of BHF Cymru. After exiting the Castle, the route winds around 5km of Bute Park's beautiful winter backdrop. Participants are invited to run, walk or jog, making it an event suitable for all the family.
All adult participants will receive a free Santa suit upon registering and children are encouraged to come in Christmas fancy dress.
Event organiser Hannah Townsend said:
"We are calling on the people of Cardiff to sign up to this fantastic event.
"It is one of the area's most popular festive events and we always get great feedback.
"There is something for everyone, whether you wish to walk, run or jog to get festively fit.
"Every participant will receive a free Santa suit, so get yourself into the Christmas spirit and take part.
"I guarantee people taking part will have fun so why not sign up today and help us in the fight against heart disease, Wales' biggest single killer."
Gwydion Griffiths of Cardiff Blues said, "Cardiff Blues are proud to be teaming up with the British Heart Foundation and Nando's to celebrate Santa's Run.
"The British Heart Foundation Cymru Santa's run is a great way for people to help raise funds for a very important charity and a fantastic way for all to get into the Christmas spirit.
"The Cardiff Blues v Montpellier game is sure to be an exciting encounter in Europe's premier club competition.
"It's great that we have teamed up with Nando's for this special offer and after the Cardiff Santa Jog we hope everyone will go to watch the Blues and enjoy a lovely meal at Nando's.
"Having worked closely with Nando's on a number of activities recently we really feel our relationship is growing from strength to strength and would like to thank them for their generosity."
Ben Browne of Nando's Cardiff added,
"We are delighted to help support the British Heart Foundation Santa's Jog.
"We here at Nando's Cardiff are big rugby supporters so it's great way to reward the runners and hopefully there will be a great atmosphere at the Arms Park for the Cardiff Blues v Montpellier match before supporters turn up to use their vouchers."
