If you outride someone, you ride faster than they do, or you cover more ground. The old picture is horses: one rider pulls ahead and leaves the others behind. You can still use it for bikes and motorbikes, but it is not a word you hear much on the street — more in stories, racing talk, and slightly old-fashioned writing. Though actually, English also lets a horse outride its rider, meaning the animal has gone further or harder than the person can comfortably handle. A few people also say outride a storm, meaning get through it on a horse or a boat; that is a cousin of ride it out, not a race. The meaning that belongs here is the race: your riding beats theirs.
