Jacek Gollob was born 27th October 1969 in Bydgoszcz, Poland. He is a former Polish motorcycle speedway rider who has twice won the individual Polish Championship (1998, 2000) and also won the team and pairs championships several times (1993-1997 and 2002). His younger brother Tomasz is also a speedway rider.
Currently – in 2017 – he is the coach of the speedway team Polonia Bydgoszcz. I got this autograph after Unia Tarnów vs Polonia Bydgoszcz match (April 9, 2017). More about rider and this card.
