Over 100 brave runners took part last year in the sponsored streak that raised almost £5,000 to help conservation efforts for endangered polar bears throughout the world. Volunteers jogged or walked the 3/4 mile course wearing nothing but running shoes and polar bear masks at the award-winning park which is home to four majestic polar bears. here are a selection of pictures from last year's event to remind you of what you can expect to see.
