Iron Passport
A worldwide gym finder for people who train when they travel — 2,700+ gyms, destination discovery, a gym passport, and day passes gyms can sell directly.
What it is: Iron Passport helps traveling lifters stay on track, anywhere on earth. It finds and compares gyms in the city you're landing in, and gives gym owners a way to reach the travelers already searching for them.
The problem: Every trip starts with 45 minutes of searching "day pass gym [city]", clicking dead links, and calling places that no longer exist.
What's shipped:
- Gym Finder — 2,700+ published gyms across 69 cities (September 2026), each page built with structured data for search.
- Destination Discovery — pick a trip, see where to train.
- Gym Passport — stamp, rate, and review the gyms you visit.
- Gym Compare — head-to-head brackets for choosing between gyms.
- For gyms — a free claim flow, plus Gym Pro ($29.99/month), which lets a gym sell day passes directly on its page.
Free for travelers — no paywall, no membership.
Approach: Search-first and answer-engine-first. Programmatic city
and gym pages, ExerciseGym and FAQ schema, an llms.txt, and an
automated growth loop that adds gym supply and handles gym-owner outreach.
