The Loch Loop course in Scotland was released in the 1.33 game release. This course is one of the longer courses in Scotland and features ~5 miles(8 kilometers) of riding. The route stays on the flatter grounds, and as a result, covers a minimal amount of elevation gain. This is a great course for a flat route or flat time trial. The best bike for this course is definitely going to be the most aerodynamic frame and wheelset that you own.
