Once you get to the end, repeat. And play these as triplets and make sure to use your pinky and first finger. Try to keep your pinky from flopping around (meaning keep it arched). This is actually pretty difficult to speed up at first because it feels awkward.
Repeat on all strings and use a metronome or drum beat to work up to speed.
