An incredible achievement.

The 37-year-old open water marathon swimmer from Colorado completed the record-breaking feat at around 6.30am Tuesday morning, more than 54 hours after she set off from the British port of Dover.

It took her more than two days to swim the 130 miles across the busy English Channel four times.

Congratulations!
