What an incredible year 2016 was for parkrun and junior parkrun in the UK. When we sat down to compile this, our first-ever annual review, it was a rare opportunity for us to take a moment to reflect. Not just on our amazing growth and landmark achievements over the past year, but how much we had matured both as an organisation and a wider movement. In 2016 we celebrated our 12th birthday, and as we enter our exciting ‘teenage’ years we are in a fantastic position to continue with our vision of making the world a healthier and happier place.
