Cycling board game published in Germany (in 1926), it's about indoor cycling and takes place on an oval track, those races are know as 6-tage rennen since they last 6 days. It has a roll & move mechanic but overtaking is only possible in straights (which have black dots) with a higher number, the overtaken rider moves to the neighboring white dot, misses a turn, and resumes the race from the black dot. You must reach exactly the last black point before each curve and overtaking in the curves is not allowed. The rider behind will stay behind losing any extra pips.
