Hints Needed Please

[rsvp]

Late in life (getting on for 70) I've come into a sport which requires me to remember seven, 500m obstacles which are on a course. Each option may be driven in any way providing they are taken in alphabetical order and are subject to certain criteria - this I perfectly uderstand. Each obstacle is completely different and has a myriad of optional courses which may be used to an individual competitors advantage. What I would like to know is, has any aber any hints on how I can remember the individual routes? Got by last year with just walking the course a thousand times but am trying to save the legs a bit this year. Need something simple to use in the heat of the moment! Thank you
Have tried this in sport but got no replies.

i'm finding it really difficult to envision what it is you are actually asking - what sport is it?

horse driving trials Bednobs. One part of the competition is to drive obstacles, each of which has numerous options. What I'm looking for is any ways to help me remember seven completely different routes.
