Hiking and jogging

Hiking and jogging are interactions that a Sim can unlock by gaining enthusiasm in the Nature and Fitness hobbies, respectively.

The player can tell a Sim to "Go Hiking" or "Go Jogging" by clicking on that Sim. The player can then send up to three other Sims in the household along with that Sim, regardless of their enthusiasm in Nature or Fitness. Pets can also go along on a hike or jog, but they count as Sims when deciding how many will go. The Sims who are going hiking or jogging will leave the lot for about one Sim hour.

Hiking
Hiking is unlocked through the hobby "Nature". Sims who have a high hobby level in nature will want to Go Hiking.

On a hike, a number of things can happen. A hiking Sim might find a nice bit of something, get a bug to put in his or her collection, or meet a new Sim or pet. On the other hand, a hiking Sim might get into poison ivy, be followed home by a skunk, or even be attacked by bees.

Jogging
Jogging is unlocked by having enough enthusiasm in the Fitness hobby. If Seasons is installed, jogging will raise a Sim's temperature. Sims can get sunburned if they go jogging when it's very hot.

Walkbys are sometimes seen jogging in the front of the house. If the walkby is a neighbor who owns a dog, the dog will jog along. Werewolves will be seen jogging only at midnight.

Jogging is also an Athletic ability in The Sims 3.
