Biking compares favorably to running in terms of cardiovascular fitness, offering a lower-impact alternative that can still deliver significant benefits. Cycling tends to be easier on the joints, making it suitable for a broader range of individuals, including those with injuries or joint issues. Both activities elevate heart rate and improve endurance, but biking often enables users to ride for longer distances without the same level of fatigue experienced in running. However, running may burn more calories due to its higher intensity. Ultimately, the choice between biking and running should align with personal preferences and fitness goals.
