The Dunav Ultra cycling route is often mistaken for a traditional race – when in fact, it’s something entirely different. So what is it about this evolving trail that keeps drawing in adventurers year after year? And how did one of Bulgaria’s most unique travel experiences transform from a bold idea into a must-ride journey?
The race-like association with Dunav Ultra goes back to its very beginning. It all started when three amateur cyclists set out on a personal challenge: to ride along Bulgaria’s entire northern border in under 48 hours. The journey soon became an annual tradition, growing in spirit and ambition, while preserving its raw, adventurous edge. Over the years, it caught the attention of the media and a close-knit community of cycling enthusiasts looking for something off the beaten path.
Since 2018, however, Dunav Ultra has been undergoing a transformation — evolving from a boutique, invitation-only event into a growing platform that champions cycling tourism across Northern Bulgaria. A key focus has been the seamless connection between the Danube River region and the Dobrudzha heartlands, forming a single, integrated adventure route. And at the end of it all? The chance to earn your very own Dunav Ultra Certificate — a badge of honor for those who complete the journey.
This shift has started to draw in a growing number of enthusiasts from all over Bulgaria and beyond — riders of different backgrounds, experience levels, and motivations. What unites them is a common spark: the urge to challenge themselves and to discover this part of the world in a truly unique way — from the saddle of a bicycle.
How the Dunav Ultra Certificate Came to Life
The Dunav Ultra Certificate first appeared five years after the route was created — a symbolic token of achievement for those who completed the journey during the official annual event. Two years later, with the launch of the Dunav Ultra mobile app and its selfie check-in feature, the initiative took a bold leap forward.
That’s when the so-called Dunav Ultra Adventure Kit was introduced — unlocking a special app feature that allows solo travelers to earn the certificate as well. No longer limited to one event per year, cyclists could now ride the route at their own pace, in their own time — whether in spring, the height of summer, or even late autumn.
In doing so, Dunav Ultra has redefined its own origin story — without abandoning it. What began as an extreme endurance challenge has evolved into a sustainable platform that promotes cycling tourism across one of Bulgaria’s most fascinating, yet often overlooked regions.
“With every passing year, the route transforms not just its own nature, but also the mindset of those who ride it — shifting the focus from reaching the destination to valuing the journey itself,” says Boris Begamov, creator of Dunav Ultra.
Dunav Ultra’s growing popularity has now reached far beyond Bulgaria’s borders. It has become the foundation for collaboration with the EuroVelo network — particularly the renowned EuroVelo 6, which follows the Danube River from its source to the Black Sea. Today, Dunav Ultra stands as a natural ambassador for promoting the spirit of transcontinental travel.
In 2024, the route even caught the attention of Lonely Planet, earning a spot in the prestigious Top 50 Best in Travel list worldwide. It was featured as a recommended destination linked to the Danube Limes — the ancient Roman frontier that once followed the course of the river.
What began as a small, boutique adventure — fueled by a desire for personal challenge and change — has now become a catalyst for regional transformation.
Your Guide to Unlocking the Dunav Ultra Certificate
It’s important to know that the Dunav Ultra Certificate is more than just a personal achievement — it’s an official recognition with a deeper meaning. By completing the route, you become part of a greater mission: to help promote over 110 towns and villages — from quiet riverside settlements to hidden gems across Northern Bulgaria, in the Danube region and Dobrudzha.
Getting your Dunav Ultra Certificate is a simple, intuitive process. All it takes is purchasing the Dunav Ultra Adventure Kit and using the features of the Dunav Ultra mobile app. With the app as your guide, you’ll follow the route and check in by taking selfies at 26 pre-defined locations — each marked in the app as a control point.
These aren’t just random stops — they’re iconic landmarks, hidden corners, and special places that bring the route’s identity to life. One selfie at a time, you’ll uncover the spirit of the Danube and the rich character of the region you’re crossing.
Once you’ve visited all 26 locations, the app unlocks the option to request your certificate. Starting in 2025, the Dunav Ultra Certificate is delivered straight to your email — ready to print, frame, and proudly display as a lasting reminder of your journey.
According to Boris Begamov, creator of Dunav Ultra:
“Over the years, Dunav Ultra has evolved from an annual challenge into a platform for cycling — and beyond. Whether you choose to embark on the route using the Adventure Pack at your own pace, or join the annual Dunav Ultra event, each experience offers something unique. Both bring meaningful value to the region and lasting fulfillment to curious, adventure-driven souls.”
One Route, Two Adventures – The Annual Event and the Certificate
Every year, at the end of summer, the Dunav Ultra route comes alive with its signature group event — a mass ride that draws up to 150 cyclists from different countries. United by a shared love of movement and a curiosity for discovery, participants take on the adventure through an official Starter Pack.
Unlike traditional races, this event winds through local villages and towns, with control points set right in the heart of the communities. Local municipalities play an active role in supporting the initiative, turning each checkpoint into a moment of connection between cyclists and the people of the Danube.
During the event, each participant chooses their own pace to complete the route and earn the Certificate — a symbol of a finished adventure and a contribution to a greater cause.
There are still a few bold riders who chase the legendary 48-hour challenge — and they’re always a sight to behold. But most participants come for the shared experience: the spirit of group cycling, the joy of meaningful encounters, and the chance to create new friendships along the way.
Unlike the summer ride with the Adventure Kit — where you can take 10 or more days to fully immerse yourself in the rhythm of the journey — the annual event tends to move at a faster pace. Most cyclists complete the route in 5 to 7 days, riding with purpose, momentum, and a collective energy that defines the experience.
Annual Prize Draw: Another Reason to Join the Adventure
Whether you complete the route using the Adventure Pack or as part of the annual event, once you earn your certificate, you’re automatically entered into the Dunav Ultra annual prize draw. It’s not just a fun bonus — it’s a small thank-you, a surprise reward for the effort and inspiration you’ve poured into your journey.
But beyond the prizes, completing the Dunav Ultra route and earning the official certificate is far more than just another cycling achievement — it becomes part of your personal story, something you’ll carry with you long after the ride is over. So if you’re looking for an adventure filled with meaning and emotion, maybe it’s time to look toward the Danube.
