Long, low-intensity efforts aren't the only way to build endurance. By incorporating short surges into a steady effort, you will increase your oxygen uptake and training stimulus. Completing a low-intensity effort with a surge every 4 minutes should feel comfortable, but the constant change in power and surging will provide you with significant gains in endurance.
