Two boys, one wearing blue and the other wearing white, are riding their bikes off a large jump on a dirt trail surrounded by trees.
Two boys are racing in the woods.
People can ride bikes on dirt trails even when they are not racing. A dirt trail surrounded by trees doesn't mean that the trail is located in the woods.
