With snow comes the risk that you'll hit ice on your route. Graman recommends staying on high terrain and avoiding low spots where water tends to pool. If your run includes sprints, first slowly jog the path you want to sprint to ensure there's no ice. "Slipping when sprinting is much more common, and we can prevent this as best we can if we do a prelap to make sure that it's a safe place to run," Graman told POPSUGAR.
