Half Moon Bay is where Silicon Valley goes to actually slow down.
The coastside city has a median age of 47.4 and a 65+ population of 23.1% — higher than the California state average — with a median household income of $157,884, per U.S. Census data. This is a population that already tracks HRV, glucose, and VO2 max; they came to bone quality through their longevity reading, not through a primary-care referral.
Healthcare on the coast funnels through San Mateo Medical Center’s Coastside Clinic — excellent for primary care but limited for advanced imaging. DXA access means driving 25-40 minutes over Highway 92 into the Peninsula, where appointment lead times can run 6-8 weeks.
HALLĒ chose Half Moon Bay because women who biohack their way to age 90 shouldn’t have to leave the coast to monitor the one tissue that determines whether they can still hike Mavericks at 75.
What Makes Half Moon Bay Different
The Cabrillo Highway location is co-located inside Upgrades in Health and Wellness, which means members can pair their REMS scan with the broader recovery and performance modalities Upgrades offers — making it a single coastside visit rather than three Peninsula trips. Tuesday-through-Saturday hours fit how coastside members actually live: weekdays for work, weekends for the trail.
The Half Moon Bay Coastal Trail runs 11.5 paved miles along the bluffs from Miramontes Point to Pillar Point Harbor — the daily trail of choice for the coastside’s senior runners and walkers. Coastal-trail mileage is excellent for bone loading, but rocky shoulder spurs and the wet-season fog account for a meaningful share of distal-radius fractures locally. Quality data — not just density — is what tells a runner whether to add load or back off.
