These guys are pretty similar to raptors in terms of reflex time. If you're quick to react, you can avoid their jumps, and slowly pick away at their health. However, they are definitely not as fast as raptors, at least on land. If you come across one, head to the nearest land, and either book it and don't look back, or keep your face to it, moving backwards, with a projectile weapon of your choice.
