Editor's Note

This week's big theme

Premium wellness real estate is booming in the UK.

At a time when pubs and restaurants are struggling, we keep seeing wellness expand, and a shift from gyms to health as a lifestyle.

Third Space is growing fast, with clubs sold out before they open. The Fifth launches its high performance members club this winter. And clubs like RecoHQ are leading the way with community-led recovery studios.

It seems hospitality isn't dying at all. It's evolving. People might not want to spend £100 down the pub on a Friday, but they'll happily spend it on a membership to a luxury wellness studio.

Traditional hospitality is evolving too, with hotels like Six Senses leading on wellness, and digital detox breaks becoming fashionable.

Which leads nicely into this week's podcast guest, Hector Hughes, the founder of Unplugged, who tells us why he steals every guest's phone for three days.

Industry News

Garmin acquires TrainingPeaks and TrainHeroic

Garmin has bought the coach-led training platforms TrainingPeaks and TrainHeroic, just days after launching its screen-free fitness tracker. It is a clear step towards one integrated platform, where a Garmin user can plan their training, run the sessions and track their recovery without leaving the ecosystem. (garmin.com)

Why it matters: Most people training seriously are drowning in subscriptions for different parts of their setup, stitching together rigid integrations just to see the full picture of their data. Garmin now owns both the hardware and the data experience, which very few companies can claim.

Proximie signs UC San Diego Health across 44 operating rooms

Proximie, the London company founded by reconstructive surgeon Nadine Hachach-Haram, has signed a multi-year deal with UC San Diego Health to deploy its software across 44 operating and procedure rooms at four hospitals. The two will also build a model trained on surgical video and workflow data. (businesswire.com)

Why it matters: Most of what happens in an operating theatre disappears the moment the operation ends, so nobody learns from it beyond the people in the room. Proximie is leading the way in training models that help surgeons prepare for, optimise and learn from each procedure at a scale never before possible.

Function Health secures $450m to scale preventive health platform

Function has taken $450m in growth financing from General Catalyst to accelerate customer acquisition. The company has been buying up companies across lab testing, medical imaging, at-home blood draws and supplements as it moves to build the most comprehensive offering in preventive health. (insider.fitt.co)

Why it matters: Most preventive health companies focus on a few core pillars. Function is positioning itself as the everything platform at an accessible price, and that is hard to compete with if you only own half of the picture.

Tramp opens £10m health and wellness club in Mayfair

Tramp Health has opened a £10,000 a year ultra premium wellness club. The core philosophy focuses on integration of training, recovery, diagnostics and nutrition rather than treating them as separate things, with a longevity doctor and AI platform building individualised protocols for every member. (robbreport.com)

Why it matters: Health is evolving as a category. A gym used to mean a £50 a month subscription to a room full of weights. People now expect a full end to end wellness experience, and will pay an exceptionally high price to get it.

Priory pilots HelloSelf's AI companion for therapy patients

Priory, the UK based mental health care provider, has started a pilot at two of its London sites giving outpatients an opt-in service that uses HelloSelf's AI companion to help remember, practise and reinforce what they have learnt between clinician-led therapy sessions. (healthtechdigital.com)

Why it matters: Reflecting on and practising what is learnt during therapy between sessions is shown to dramatically improve progress. A technology-enabled way to bridge the gap is likely to offer better patient outcomes than waiting a week for the next appointment.
