Difficult how?
DIFFICULT BY LENGTH
I am not sure what you mean by your question. If you mean "difficult to complete a lap in a short amount of time," then the longer tracks will be more difficult. The Rallyman GT tracks are rated for length, measured in hexagon tiles. There are three length groupings, short (14-), medium (15-21), long (22+).
DIFFICULT BY TIME (solitaire mode)
If you want to compare tracks directly for speed, you can compare the best recorded solitaire mode times.

NOTE: Solitaire mode is significantly different from competitive mode.
