East Fjords Longevity Reset — 5 Days

This is the nerdiest retreat in Iceland, and proudly so. You arrive to a morning of baseline testing: VO₂ estimate, HRV, mobility screen, sleep questionnaire. The next four days train what the data shows: graded fjord hikes, cold adaptation in the sea, sauna protocols, strength foundations, and evening lectures your inner sceptic will enjoy. Meals are built by our nutritionist around local fish, lamb and greenhouse produce. You leave with a written report and a 12-week plan. Run by Dr. Arnar Þórsson (sports medicine) with a team of four. Eight guests per cohort.
