Bending the Trend Line

I have swum for and coached a number of age-group swim teams.  When I was 14 I joined our community pool’s swim team, at the suggestion of a girl I had interest in, and I really enjoyed it.  I later coached that team, and swam for and coached my high school team and swam on an AAU team in high school.  For the last eight or so years I have been on a Master’s club for post-college swimmers.  We have meets and, like the summer community pool leagues of my youth, the results are posted by age bracket.

There is an interesting phenomenon in age-group swimming.  When you are young, it’s to your advantage to be at the top of your age group—in the 13-14 age group, the 14-year-olds have the advantage over the 13-year-olds.  As you age, however, at some mysterious tipping point the advantage switches to the younger members of an age group. 

The U.S. Masters Association has national competitions and sets qualifying times for the various events by age bracket.  A goal of mine has been to qualify for nationals in an event someday. 

The good news is that qualifying times rise with the age brackets.  I’m currently in the middle of an age bracket and anxiously awaiting the time in two years when I will enter the next bracket.  The problem is that swimmers slow down as they age. 

The graph below shows the dilemma I am facing.  The blue line shows the qualifying-time trend for an imaginary event.  The red line is my expected time in seconds for that imaginary event as I get older.  While the lines eventually converge, meaning that my time would qualify for nationals, the trend shows that I wouldn’t qualify until I’m 110 years old. 

No matter.  I’m going to keep trying.  If I can stay healthy, work out harder and get a little stronger I think I can bend that red line down enough to qualify for an event—any event—when I enter the next bracket in 2016.  It’s something to work toward.

Jack and Erin's Wedding!

This past weekend Jack married Erin Breslin in Santa Barbara. Erin is smart, sassy, strong, funny, and beautiful. She and Jack are nearly inseparable, and when they are together, they talk and laugh nonstop like two school kids. As Donna noted in her beautiful, heartfelt remarks at the rehearsal dinner, it's hard to know what they have left to talk about after carrying on this continual conversation for more than three years. It is obvious to anyone who sees them that they are head over heels in love. Donna and I had met Erin's parents last December in Philadelphia. We immediately became friends and found that we shared a lot of common values -- particularly the importance of family. It was great to see them again in Santa Barbara and to meet their son Gerard and many of their siblings and in-laws. It also was great to meet some of Jack's fellow YouTubers. There's a culture of camaraderie in the industry, and many of them were eager to help Jack when he was g...

Great Chesapeake Bay 4.4-Mile Swim

I swam the Great Chesapeake Bay 4.4-Mile Swim last Sunday for the fourth time.  It was the first time I had participated since 2011.  Back then I wasn’t in the best of shape and the conditions were very tough.  The air temperature was 95 and the water temperature above 80.  It was a grueling, unpleasant grind.  I remember telling Donna to never let me do it again. This time it was a completely different experience.  I really enjoyed the swim.  The air and water temperatures were just about perfect (80 degrees and 72 degrees), although seas were pretty rough—especially during the second half of the swim.  I had a better attitude going in, I was physically and mentally prepared, I had a music player—a gift from my kids—to keep my head clear and I was excited for about a week before.  Maybe I needed something to be excited about.   I was excited on the early-morning drive from Columbia, past Annapolis and acr...

Call Me Ishmael

I’ve just finished re-reading Moby Dick , Herman Melville’s American masterpiece about Captain Ahab’s battle with destiny, madness and the great white sperm whale that demasted him of a leg. It’s one of the most remarkable books I’ve ever plowed through. Ishmael, the book’s narrator, signs on to be a shipmate on the whaling ship Pequod for a three-year expedition because he’s drawn to the sea as a way to clear his head and experience the ocean’s vast wildness. As fate would have it though, Ahab, captain of the Pequod , has no intention to harvest as many sperm whales as possible, but to hunt down and kill Moby Dick.   I’m fascinated by literary names. Ahab was named by his “crazy mother” after a biblical king of Israel who devoted himself to the worship of false gods. Like his namesake, Captain Ahab is devoted to the maniacal pursuit of his false god, vengeance. Ishmael in the Bible was the bastard son of Abraham and his wife’s slave Hagar. Abraham’s wife Sarah ban...
