OK, so here's my original track idea for Prague. I liked to call it Ying-Yang and you can see below why
This layout is much more dominated by straight and fast sections. The total length is 5.6 kilometers (about 9 miles). It runs counter-clockwise.
There are two straight sections, the S/F straights ore than 900 meters long and the "upper straight" which is in fact two straights connected by a very fast chicane.
