HONOLULU (AP) — A Grand Canyon river rafting guide who aimed to become the first American woman to row across the mid-Pacific solo has completed a record-breaking journey from California to Hawaii.

Hundreds gathered to cheer on Kelsey Pfendler as she pulled into a Honolulu harbor Friday night on her 21-foot row boat, Lily, after nearly a month and a half at sea, local media reported.

Pfendler, who launched from Monterey, California, in May, set out to become the first American woman, youngest woman and fastest woman to make the more than 2,400-mile journey solo, according to her website. Hundreds of thousands of people followed along with her journey on social media, where she shared the highs, lows and quirks of her trek in videos taken as she bobbed alone on the vast ocean.

Pfendler appears to have broken both the previous women’s speed record as well as the men’s speed record, according to records maintained by Ocean Rowing Society International, which adjudicates ocean-rowing achievements for Guinness World Records. The organization didn’t immediately respond to requests for comment from The Associated Press about Pfendler’s finish.
