The Bflow agency has become a sponsor of the Tannaberg family racing stable in Posumavi region. This young racing stable was established in 2009, when Army General Josef Becvar bought from MD Frantisek Cizek from Cesky Krumlov, a pregnant mare Haraletta, to whom the first racehorse Herbebois was born the following year. The stable has been registered by the Jockey Club of the Czech Republic since 2012. Horses from the Tannaberg stable were trained in the past by Mrs. Helena Blazkova and Mr. Karel Germic in Lysa nad Labem and Mr. Jaroslav Drlik in Prague-Chuchle. Since 2019, Mrs. Martina Havelkova has been the coach and also the rider of the stable.
