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. If the Sim is a young adult living in a college dormitory, the player may be able to send dormies along on the hike or jog, even though they are not considered household members. The Sims who are going hiking or jogging will leave the lot for about one Sim hour.
Hiking is unlocked through the Nature hobby. Sims who have a high enthusiasm level in Nature will want to Go Hiking. Before Sims leave the lot for a hike, they will normally change into everyday clothes. If Seasons is installed and the temperature is low enough, they will change into outerwear. Also, hiking may raise a Sim's temperature if Seasons is installed.
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 is unlocked by having enough enthusiasm in the Fitness hobby. Sims who have a high enthusiasm level in Fitness will want to Go Jogging. Before Sims leave the lot for a jog, they will change into athletic wear and do stretching exercises. Sims can build the body skill and gain fitness by jogging. 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.
