In May 2025, Michael Zervos broke the Guinness World Record for the fastest person to travel to every country on Earth—completing the journey in just 499 days. With the Matador SEG45 Travel Pack on his back, he crossed borders, dodged bribes, ate everything from tarantulas to cow hoof, and connected with people all over the world.
We caught up with Michael to uncover what it actually takes to do the impossible, and how he accomplished it with the SEG45 Travel Pack.
WHAT ARE THE GUINNESS WORLD RECORD REQUIREMENTS FOR 'VISITING' A COUNTRY—DOES A LAYOVER COUNT?
Technically, the Guinness’ rules only require that you set foot in the country. However, you must collect a specific set of evidence.
The Guinness’ required evidence:
- An approved route beforehand, journaling every day exactly what you did
- Two witness signatures from those who saw you in the country
- Digitized receipts (hotels, food, entertainment)
- Digitized tickets (boats, planes, trains)
- GPS waypoint in each (.gpx files)
- Videos showing you there
- Photos showing you there
- Any media you received along the way
Instead of taking the easy route, Michael stepped deeper into each country—meeting contacts, chasing his mission, and actually experiencing the world.
“I made a promise to myself that I would at least stay one night in every country. On average, I spent 2.5 days in each place–though I spent less time in microstates or certain small islands. The most I spent was 6 nights in the Marshall Islands.” – ZERVOS
