Answer :
People will need to go through more than one obstacle at three places in the course: The 1/3 mark, the 1/2 mark, and the 2/3 mark.
The tires are at these spots
--\--\--\--\--\--\
The cones are at these spots
----\----\----\
And the hurdles are here:
------\------\
When you combine these:
--\--\\--\\--\\--\--\\\
You get two marks at the 1/3, 1/2, 2/3, and Final spots (Final can be 1, 2/2, 3/3, or 6/6.)

the people will have to go through these obstacles more than once:
The tires are here
--\--\--\--\--\--
The cones are here
---\---\---
but this would be the hurdle which is at the end of half the course
----\----
only one spot so it would only be the first two cuz they are repeated
