2020 WOWSA Awards
The Lake George two-way crossing by Caroline Block, Ph.D. was nominated for the 2020 WOWSA Awards in the World Open Water Swimming Performance of the Year category with the following nomination: Lake George has been crossed by marathon swimmers since 1958, but only infrequently to say the least. The 51.8 km Queen of American Lakes is a long, narrow lake in upstate New York. Dr. Caroline Block, the only person to attempt two-way crossings of the [[North Channel] between Northern Ireland and Scotland, took her endurance, willpower and support team to the shores of Lake George to attempt an unprecedented 103.6 km two-way crossing. A tough 52 hour 24 minutes later, Block emerged victorious and smiling. The 36-year-old anthropologist became the first person to attempt and complete a double. For yet another multi-day non-stop marathon swim by a modern-day Renaissance Woman, for pushing herself beyond expectations and setting a world record, and for being so positive, personable and passionate about pioneering new swims, Dr. Caroline Block of the USA is a worthy nominee for the 2020 World Open Water Swimming Performance of the Year.
2018 WOWSA Awards
Caroline Block was nominated for the 2018 World Open Water Swimming Woman of the Year for the following nomination: Dr. Caroline Block is an American marathon swimmer who continues to push the boundaries not only for herself, but the entire channel swimming community. An anthropologist on dry land, she pioneered a 55.7 km south-to-north crossing of Lake Cayuga in New York. Although her traverse took 21 hours 36 minutes, it was a mere warm-up for her second attempt of the hardest two-way crossing of the Oceans Seven: a 70 km double of the North Channel. Taking off from Northern Ireland, the 34-year-old finished her first leg in 16 hours 45 minutes - and turned right around to head back, an unfathomable attempt for nearly everyone but herself. After a total swim distance of 61.2 km and 25 hours 58 minutes, Mother Nature won the battle. Her attempt was followed by thousands via her tracker and her effort was inspirational and educational for many more. To culminate her season, she became the first woman and second individual to swim 44.3 km from Santa Rosa Island to the California mainland, finishing in 20 hours 36 minutes. For attempting the most difficult two-way channel crossing in the world again and pushing herself immeasurably before running into impassable tides, for humbly accepting praises and compliments from admiring swimmers worldwide, and for being so positive and passionate about attempting and pioneering unprecedented swims, Dr. Caroline Block of the USA is a worthy nominee for the 2018 World Open Water Swimming Woman of the Year.

Dr. Caroline Block is an American marathon swimmer who attempted to push the boundaries to the extreme in 2017. An anthropologist on dry land, she takes things to a whole new level in the open water. In addition to participating in the U.S. Winter Swimming Association National Championship early in 2017, she set a new woman’s course record swimming the 52 km length of Lake George in New York in 19 hours 21 minutes and then embarked on a legendary attempt – a two-way crossing of the bitterly cold, jellyfish-strewn North Channel between Northern Ireland and Scotland. While the best of the best and the most hardened open water swimmers in the world have completed a total of 57 one-way crossings in history, Block followed up on her 2016 North Channel single by attempting the first two-way crossing this August. For swimming 88 km in 12°C water over 28 hours 55 minutes before running into impassable tides, for attempting the most difficult two-way channel crossing in the world, for not relenting until running headlong into insurmountable tides on her return leg, Dr. Caroline Block is a worthy nominee for the 2017 World Open Water Swimming Woman of the Year.
