Everyone knows that Santa has a belly like a bowl full of jelly, but is that what you’d wish for yourself? To combat over-indulgence this holiday season, French insurer Allianz – a great supporter of health and fitness – and its agency Ogilvy have created RUNMIX: a 30-minute exercise soundtrack consisting purely of Christmas songs. Remixed by the musician Møme at the perfect tempo for running, squats and similar activities, the selection of tracks can be downloaded from all the most popular music platforms. Why 30 minutes? Because 30 minutes of physical activity a day can reduce the risk of heart problems by 30 per cent. So try to make sure that, this Christmas, it’s not just Rudolph and his friends who are doing all the running.
