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.

  • Swimming times will degenerate geometrically with age, so using a straight line approach to estimate a relationship between age groups may be misleading. Also, outliers such as Rick Colella and Laura Val would further skew this relationship.
