 10 minutes later, maybe half an hour later, not 62 hours later. But we don't share Ross Edgley's vision of a perfect summer day or days. Mr. Edgley is a marathon swimmer from the UK. In 2018, he became the first swimmer to circumnavigate the British mainland. And this weekend, he spent 62 hours in the Yukon River, swimming a total distance of 510 kilometers as he set out to break the record for the longest nonstop river swim.
