Time Out says
The UK’s largest outdoor fitness festival returns to Hackney with a three-day programme of activities to help you work up a nice sweat. Take part in a host of free fitness classes led by Nike, or get stuck into sessions from Gareth Bale-endorsed rowing studio Rowbots, high-energy drum n bass boxing class Fight Klub or wellness dance organisers Morning Gloryville. For those who are really keen to get their heart pumping, there’ll be a free-to-enter 5k on Saturday. Or if you’d rather be a spectator, simply head down to Hackney Marshes to cheer on the runners taking part in the Hackney Half and soak up the atmosphere at the Market on the Marshes, where you’ll find food trucks, local brewery bars and stalls from independent Hackney retailers. In the words of Olivia Newton-John, ‘Let's get physical’.
