"This Girl Can" hit our screens on 12 January 2005 - and in an instant, how women exercise changed. Developed by Sport England, the campaign included cinema, outdoor, and social media advertising - and a Twitter campaign using the hashtag #thisgirlcan.

Behind this phenomenally successful idea were many people including Kate Dale, Campaign lead for This Girl Can. Kate has been at Sport England since 2004, and continues to lead this award-winning, disruptive campaign to get more women more active. 

Did the campaign work? Between January and July 2015, phase one of the campaign resulted in over 95m online views; 733,000 mentions on social media; 581,000 fans or followers across all platforms; over 1.2m visits to the website; it was talked about a thousand times a day on social media in over 110 countries... more importantly, 2.8m women were more active, of those 1.6m re-started exercise and 250,000 more women were active at least once a week (vs men, who stayed unchanged).
