Tormund and his crew move in different directions than the army does. Neither of them made a direct line to Winterfell.
Also, like I said it's the fact that they have horses (as the crows said)....which move a hell of a lot faster than the dead army.
The Wall to Winterfell is like 630 miles roughly. A horse is going to ride at say 30 MPH that's 21 hours worth of travel time. So assuming they stopped and rested, they'd get back within 2 days easy.
Meanwhile, the dead army was walking at a slower than usual pace. The average human walks at 3 MPH, but it's safe to say those guys move even slower. Even so, assuming they're moving at a 3 MPH pace that means it'll take them over 8 days to reach Winterfell.
