In 2020, we organized our first sim racing tournament in iRacing. The pandemic and lockdown accelerated an idea we had since 2018. Of course, a key role in this was played by Iskren, the driving force behind the entire project to this day. After many years in Richard Burns Rally, he transitioned to iRacing.

Our experience in real motorsports certainly helped us dive into this adventure with confidence. Time has passed since then. Many people have joined the project and have significantly contributed to its overall growth. Some have moved on, but most of the core team continues to develop the wonder known as sim racing.

Over the course of four years, we organized nine seasons of the national sim racing series in Bulgaria. We managed to create a community that grew from 10 good friends to nearly 1,000 members. In 2021, we became the 14th official national championship in iRacing. We went through various car categories, worked hard, made mistakes, and learned from them. We still do—and we enjoy it.

In 2022, we organized a Richard Burns Rally championship, stepping outside of iRacing for the first time. In 2024, we organized and held our first drift championship, which attracted over 300 participants from around the world. That’s when we faced a tough dilemma: should we continue growing nationally or open up to the world? In the end, we chose the latter. From Bulgarian Electronic Racing Series, we rebranded to Best Ultimate Leagues and Electronic Racing Series, keeping the same abbreviation—BULERS.

Throughout all this time, we’ve organized over 500 races, almost all of which were broadcast live. We’ve worked with established brands like Acer, Heineken, PokerStars, Pringles, Red Bull, and others. We’ve also organized several charity tournaments.

Since 2025, we’ve been working hard to elevate the BULERS brand to a global level and become a recognizable platform where every sim racing enthusiast can find the right environment for growth, competition, and expression.
