Realistic Roleplaying Tips:

Slow down! You don't need to run/jump everywhere. Take a walk in the forests.
If you do run while you travel, take the occasional rest.
Only travel in good weather. If you must travel in poor weather, wear appropriate attire. Consider running to find a camp or cave to wait out the storm.
If you come across a village, don't keep going. Unless you're doing something important, stop by. See how the livestock and townspeople are doing.
Spend nights in inns or taverns. If you are caught in the wilderness at night, stop por the side of the road as if you were camping.
