I've gone against skilled Udyr players, and they were difficult to run away from. Given all of his various forms it seems like he can be very successful and find you and stun you with his bear form long enough to find other champs to help with the kill, or he'll just kill you himself. If you have Flash or some other Summoner spell you can use then it can be easier to run away, but if it's on cooldown it can be the difference between managing to survive and dying.
