Kristof Vandewalle won the 25km time trial stage from Adriano Molari and Britain’s Steve Cummings in third.
After winning the two previous stages Majka still had work to do today to hold off the Movistar pair Benat Intxausti and Jon Izaguirre who were only 18 and 22 seconds behind, respectively.
Majka, now known for his climbing having won the King of the Mountains jersey at the Tour de France, managed to limit his losses and finish 13th in the time trial to take the overall win by just eight seconds.
Majka becomes the first Polish rider to win his home tour in eleven years when Cezary Zamana in 2003. Omega Pharma’s young neo-pro Petr Vakoc, who held the yellow jersey earlier in the race, held on for a top ten finish.
