I remember the moment a few years ago while watching TV when I realized that if I were riding in the Tour de France, at age 42 I’d be the oldest person in the race. It hit me that my dream of racing in cycling’s biggest event was over…it was not going to happen.
Not that I’d been competing, let alone training seriously, on the bike for a number of years.
Or that not even in my “prime” years for competitive cycling would I have been good enough. It’s just that now I had an excuse…. I was too old, too far past my prime years.
So what happened? Is there a physiological reason people in their mid-40’s are no longer able to compete at the professional level in most sports, or is it a constellation of challenges, such as the time devoted to training, motivation, managing kids' schedules or busy work demands?
“I’m old” is the common refrain for why we get worse at athletics as we age. But here’s what’s really happening in the body through the years to make world-class performance less possible. And, interestingly, there are a few physiological elements that contribute to athleticism that don’t seem as affected by aging.
The ‘sweet-spot’ age
In most sports, there is an age “sweet spot,“ at which the combination of physical, technical and strategic abilities comes together.
In most sports, this age sweet spot falls in the mid-20’s to early 30’s. Although there have been numerous examples of Olympians competing, and sometimes winning medals, over the age of 50, the vast majority of these come from sports requiring exceptional skill and less aerobic or anaerobic power, such as the shooting events, sailing, equestrian and fencing.
For endurance events, the upper cap for competing at the sport’s highest levels appears to be around the age of 40.
Chris Horner won the 2013 edition of the Vuelta a Espana, Spain’s version of the Tour de France, just shy of his 42nd birthday, making him the oldest winner of a Grand Tour in cycling.
The oldest Olympic marathon winner was the 38-year-old Romanian athlete Constantina Dita Tomescu, competing at the Beijing Olympic Games.
Dara Torres, at the age of 41 in 2008, is the oldest swimmer to compete in the history of the Olympics, missing the gold medal in the 50-meter freestyle by hundredths of a second. But these examples are the exceptions, not the rule.
