Part of a Community

CrossFit Sydenham isn’t just a new gym - it’s built on a strong foundation.

As the sister box to CrossFit Catford, we’re already part of a thriving, established community that’s been growing and supporting athletes of all levels for years. With the same experienced coaching team, shared values, and welcoming atmosphere, we’re here to help more people discover the power of CrossFit.

One community, two locations - stronger together.
