Hall of Fame
The best in the world are listed on two pages:
Hall of Fame 1:free style
Hall of Fame 2:default routes
To qualify for the Hall of Fame 1, you can run on any possible route.
To qualify for the Hall of Fame 2, you have to stay within the fences and walls, and you have to pass all checkpoint banners.
The Hall of Fame 2 was started in March 2012, so there are still some gaps to fill.
