What is one aspect players prepare for when playing on courses with a lot of elevation changes?

Players preparing for courses with significant elevation changes need to adapt their club selection and distance control due to the impact that elevation has on ball flight. When playing on hilly terrain, the elevation can affect how far the ball travels; for instance, shots played uphill tend to require more club because the ball doesn't travel as far, while shots played downhill can fly farther than expected.

Additionally, the reduced air density at higher elevations can lead to longer distances for each club compared to areas at sea level. This requires players to carefully evaluate their approach to each shot and make informed decisions about both club choice and the distance they can expect to achieve with that club. The ability to adjust to these factors is crucial for scoring well in such environments, making this aspect critically important in preparing for these courses.

The other options focus on more restrictive or less relevant practices that would not adequately prepare a player for the complexities that elevation changes introduce in their game.
