Four intrepid women have just broken the world record for rowing across the Pacific Ocean, completing the feat in just over 34 days. The Lat35 team, which included Libby Costello, Sophia Denison-Johnston, Brooke Downes and Adrienne Smith, completed the 2,400 nautical miles from San Francisco to Honolulu on Tuesday.

Speaking to Good Morning America, Denison-Johnston explained that the unassisted crew took two-hour shifts – sleeping for just 90 minutes at a time. The record-breaking voyage was the first time anyone in the boat had rowed unassisted and in the open sea.

It was all part of The Great Pacific Race, which starts from San Francisco’s Golden Gate Bridge and ends on the Oahu shores of Hawaii. Since the inaugural race in 2014, the route has been rowed by 16 Guinness World Record holders – including the first blind athlete to row the distance.
