TORCS is cross country/hare scramble races. Not sure exactly what a enduro sprint is. We line up in rows by class, start dead engine 1 minute between rows. Race for 70 minutes plus finsh your lap obviously. Courses are varied, not sure of this year but last year had a couple that had some mx involved. Usually go arounds on jumps if you just don't want to do them. Most are woods only with some grass track stuff at some venues.

Only been to Revs once but if I got the right track, it had a long, rough grass rack section and some very good woods riding. Of course he tries to vary tracks from year to year.

Hope this helps.
