Jogging will give you endurance, but you need to work on your speed. Practice sprinting at short distances; sprint for 15 seconds and rest for 15 seconds. Another drill is to start at the baseline center, shuffle sideways to the left corner (of the baseline and singles side line), then shuffle along the baseline to the other corner (right). Get back to the baseline center and sprint to the left corner of service line and singles side line; from there back pedal to baseline center (As shown in the image). Time your self and sets target to improve your footwork.
