Third Space Marylebone

A Marylebone Club With London Roots

Third Space Marylebone sits in a part of central London that values rhythm. Marylebone moves at its own pace, quiet streets, independent names, and a quiet confidence that does not need to shout. Third Space was founded in Soho in 2001, and then grew into a collection of London clubs built for people who take training seriously. The Third Space Marylebone club opened at The Marylebone Hotel in 2011, and it has operated in Marylebone since then. That track record gives members something rare in fitness: continuity. A place that is not chasing trends, just delivering standards, day after day. Visitors can expect a calm welcome, considered spaces, and the sense that time spent here will pay back in energy and clarity, not just sweat. Some come to train before the day begins, others to reset between meetings, and many to finish strong.

Training and Recovery Done Properly

Inside, the promise is capability wrapped in comfort. As a luxury health club, it offers two floors of training space, bespoke functional rigs, a sprint and sledge track, strength equipment, and performance Wattbikes, plus a purpose-built yoga studio. Studios host expert-led classes across strength and conditioning, cycle, combat, and mind and body formats. Recovery is built in, with a three-lane pool, sauna and steam room, and the option of physiotherapy. Changing rooms are treated as part of the experience, with Cowshed products, fluffy towels, and grooming tools, plus an optional wash, dry and fold service. Members can also book personal training and use on-demand sessions through the brand’s app when they are away from the club. The club describes its classes as award-winning and led by leading instructors. Formal accreditations are not publicly stated, but established travel and spa industry press have covered the Marylebone opening and facilities, and Third Space is regularly included in editorial selections of London’s high-end gyms. It suits members who want training to feel like a serious part of city life, not an afterthought.
