<human>: Which is better: running or biking?
<bot>: Running is a great way to get in shape, stay healthy and have fun. It can also help you build up endurance, speed and stamina. On the other hand, biking is an excellent form of exercise that provides cardiovascular benefits, strengthens your muscles, and can be done at a much slower pace than running. Ultimately, it depends on what you are looking for when choosing between running and biking.
