Came across this article in Outside about a rash of "FKTs" in ultra running last year:
https://www.outsideonline.com/2386976/fkt-fastest-known-time-records-appalachian-trailFor many, it seemed a foregone conclusion that Karel Sabbe would be awarded the male FKTOY for his herculean showing on the AT. The 28-year-old Belgian dentist and relative newcomer to the world of ultra-running did what many people thought was impossible: he not only bested Joe “Stringbean” McConaughy’s seemingly unbeatable 2017 record, but he did so by four full days. Sabbe’s FKT time stands at 41 days, 7 hours, and 39 minutes. He ran through some particularly awful weather in the White Mountains and was up before dawn every day, finishing his miles before sunset.
The AT is 2,200 miles long. He averaged a little under 54 miles per day for more than a month with no days off.
Next frontier, adarq?
