Computomarx Steeplechase Courses were designed to correct the two chief problems in constructing a steeplechase course. These problems are:

- Accurate measurement of the water jump
approach and return so that a true 3000 meters is run. Many
steeplechase courses are set out using methods which either:
- measure the approach and return with a wheel
- drive pins in the track the required distance out from the curb and measure around them with a tape
- join the water jump to the track with circular arcs which do not join smoothly to the track as discussed below

- The joining of the water jump approach and
return to the main track such that no abrupt changes in curvature or
"corners" are present. Mathematically speaking, this says that the
first derivatives of the track and paths to the water jump must be
continuous at their junctures. Improper joining of the approach and
return paths to the track requires the athletes to slow down and run
wide twice each time the water jump is negotiated, a total of fourteen
times. Obviously this condition results in slower times for the race.
## COMPUTOMARX SOLUTIONS

Computomarx Steeplechase Courses solve both of these problems at once by one of three methods.

- Using portions of ellipses for the water jump approach and return for either interior or exterior water jumps
- Circular arcs joined by a straight section primarily for interior jumps
- Extended straightaways with circular arcs of the same radius as that of the main track joining the jump for exterior water jumps.
