Achievement of the Oceans Seven
With her May 20th crossing of the Strait of Gibraltar, she has now achieved the Oceans Seven – as the oldest person – male or female – to do so. An incredible total of 11,253 days elapsed between the date of her first channel crossing in the English Channel and her seventh channel crossing in the Strait of Gibraltar.
Talk about her persistence, diligence, and patience – 30 years 9 months and 22 days between her first Oceans Seven crossing when she was 30 years old and her last when she was 61. This has also set a new standard for the longest span to complete the Oceans Seven.
After her final Oceans Seven channel in a tandem swim with her daughter Julia Cleveland Green and Emily Frank, she suggested that the EKA Magic Jewelry store in Tarifa, Spain become the central meeting spot for swimmers of the Strait of Gibraltar. Owner Ivan Queredo posts pictures of successful Strait swimmers wearing his jewelry.

The mother-and-daughter duo have been swimming together a long time…

Thank you for this very comprehensive article. I’m actually 61 years old, not 60, making me the oldest person to complete the Oceans Seven. 👵
61? In today’s marathon swimming community that is on the young’ish side. You still have at least 2 decades to go. Minimum. Keep it up. Congratulations.
You Betcha!!!
