Six Days of Groningen
The Six Days of Groningen was a short-lived six-day track cycling race held annually in Groningen, Netherlands.
It was contested in the Martinihal Groningen from 1970 to 1972. After 2 successful editions, the public interest for the 1972 Six Days became so poor that the financial balance was negative.
In 1979, the race was organized again as part of an event Topsport' 79, but once more the public interest was minimal. It turned out to be the final edition.
