Two Locations

3 Aces CrossFit offers two of the best training facilities in London.

Come shake off the stress of city living at our 3,700-square-foot urban oasis in Kennington. Nestled in the heart of London, Kennington has plenty of space for no-holds-barred CrossFit, plus an atmosphere of camaraderie our members love so much you’ll catch them hanging out in our lounge on Friday nights. Set in two railway arches with exposed brickwork, Arch 1 has an extension on the back that’s unlike any other CrossFit in the city. Arch 2 offers artificial turf and strongman kit. All this, combined with Kennington’s outdoor area, easy access to running routes, and capacity for full-length rope climbs, make it easily one of the most intriguing and well-equipped gyms in London.

Our Lee Valley location, at 2,800 square feet inside a top athletics centre used by Olympic athletes, is the only one of its kind in Europe. Our box is sandwiched between a 200-metre indoor track and a 400-metre outdoor track where you’ll see Olympic athletes training for their next event. What better way to get your head in the game of training than to work out next to some of the world’s most elite athletes?

Reviews
  • Such a great space, really well equipped, excellent range of equipment. The highlight is definitely the coaching though. All three coaches are extremely knowledgeable and so friendly. Would highly recommend.

  • One of the best CrossFit boxes in London. A fantastic space with excellent facilities and top notch coaching from three of the best coaches in town. Rich, Mark and Caspar are exceptionally good at tailoring training to the individual's needs.
