One of the men who was a dominant figure on the professional marathon swimming scene in the 20th century was American Paul Asmuth.
Asmuth won 7 World Professional Marathon Swimming Federation titles in the 1980’s and is an inductee in both the International Swimming Hall of Fame and the International Marathon Swimming Hall of Fame for winning several dozens of long and difficult marathon races from Canada to Italy.
When asked to describe his toughest workout over the course of his career, Asmuth recalled a long day in the office at the Mission Viejo Nadadores pool under the helm of USA Swimming Olympic and National Team Head Coach Mark Schubert.
Then Mark told us that we had to go 10 x 75 [yards] on 45 seconds before we could get out.” [note: approximately equivalent to a 47-second pace in a 25-meter pool]
“I was only able to make 4 of them on the first set. But he made us do it again. So I had to try again. But, I only made 6 or 7 on the second set. Mark STILL didn’t let us out. But, I finally made all 10 on the last set.
That was REALLY, REALLY hard.”
