Most endurance athletes plan for recovery days. Tomasz Sobania planned to run through them — and on June 28, 2026, he crossed the finish line in Times Square having done exactly that.

Fifty consecutive marathons. Fifty US states. He started at the Golden Gate Bridge on May 10 and finished in Manhattan forty-nine days later — one day ahead of schedule, and one day faster than a record that had stood for twenty years.

It was never really fifty marathons. It was fifty mornings of standing at a new start line on a body that had already run the day before, and the day before that. Marathon 27 on legs that had carried him through 26. Marathon 50 on a body that had covered over 2,100 kilometres with only hours to recover between each one.

The question was never whether Tomasz could run a marathon. It was whether he could do it again tomorrow morning — for forty-nine mornings in a row.

He did. Every step fuelled by Vitargo.

Designed with a certified sports nutritionist and performance expert, Tomasz's fueling protocol was built around one non-negotiable: the carbohydrate source had to clear the stomach fast, deliver energy immediately, and leave nothing behind to cause problems on the road.

That ruled out every standard carb drink on the market.

Most sports drinks are built on maltodextrin — a short-chain glucose polymer that's inexpensive, widely used, and slow to leave the stomach. For a single event, that's manageable. Across 49 consecutive marathons, that accumulated GI load would have ended the expedition before it reached New York.

Vitargo is different at the molecular level. It's the only fuel Tomasz trusted for all 2,100 kilometres.

Before each marathon
Maximised glycogen stores without loading the stomach. Vitargo's large-molecule carbohydrate passed through without the osmotic delay that causes bloating, letting Tomasz load carbohydrates the night before and wake up ready — not heavy.

During each marathon
Stable energy delivery with minimal GI impact, mile after mile. Vitargo empties from the stomach with a half-emptying time of 17 minutes, against 33 minutes for standard maltodextrin drinks — fuel reaching working muscles faster, without sitting in the gut mid-effort.

After each marathon
Accelerated glycogen replenishment before the next start line. Research shows Vitargo drives 70% faster muscle glycogen resynthesis in the first two hours post-exercise compared to standard carbohydrate drinks. Over 49 days, that two-hour window was the difference between finishing and not starting again.

It's the science that carried Tomasz through 50 states without a single day off.

Most carbohydrate drinks are built on small, high-osmolality molecules that slow gastric emptying — the body's built-in brake on fluid and energy delivery during exercise. The stomach senses a concentrated solution and holds it back.

Vitargo is built from a unique high-molecular-weight glucose polymer derived from starch.

Its extremely low osmolality — around 62 mosmol/kg compared to 336 mosmol/kg for standard carb drinks — means the stomach never registers it as a concentrated load.

It passes through faster. Energy arrives sooner. For 49 days straight, that difference is what let him line up again.

For 49 days, the media team documented every marathon, every recovery, every new start line — from the Golden Gate Bridge to Times Square.

Now the expedition is history: 50 marathons, 50 states, a 20-year record broken.
