Who can swim their age?

Turned 50 yesterday, so I tried to swim a 50 sec 100 free. The best I could do was 52 with fins. Who has tried this without fins and been able to match their age? I think it's a good challenge. I suppose this feat could be done as early as mid 40's for some, or very few.

  • As far as I can tell, David Sims was the youngest guy to do it, swimming 46.46 at age 47. Actually Matt Biondi accomplished this last spring at the Nationals in Santa Clara in the 100 free with a time of 46.83 and he was 2 years older than his age at 48 and he did not where a super suit.
