“All of our trips are designed to satisfy experienced riders,” Mr. Hampsten writes on his Web site. To train, he suggests, “you should ride at least 100 miles a week for at least 6 to 10 weeks” on routes with “as many hills as you can find.”
So I had an image of what our fellow cyclists would look like when my husband, son and I arrived in Castagneto Carducci for a cycling vacation. They would look like Mr. Hampsten, who at age 45 remains boyishly thin and agile, bouncing with energy.
I was wrong. For the most part, our group consisted of ordinary-looking, mostly middle-age men and a few middle-age women.
These were serious cyclists. One of them was Bob Eastaugh, a 63-year-old justice on the Alaska Supreme Court who said he rode mostly to stay in shape for his true passion, downhill ski racing.
And our trip was challenging. The longest hill was 15 miles, the steepest had a 15 percent grade, the longest one-day ride was 90 miles, and the terrain was never, ever flat. It is hard to imagine that a group of middle-age adults could have handled an equivalently difficult 10 days of running. What, I wondered, made bicycling different?
It turns out that others, too, have been struck by the paradox of bicycling fitness.
“When I first got into cycling, I would see cyclists and say, ‘O.K., that’s not what I perceive a cyclist to be,’ ” said Michael Berry, an exercise physiologist at
He came to realize, he said, that cycling is a lot more forgiving of body type and age than running. The best cyclists going up hills are those with the best weight-to-strength ratio, which generally means being thin and strong. But heavier cyclists go faster downhill. And being light does not help much on flat roads.
James Hagberg, a kinesiology professor at the
“In running, when you see someone who is obviously overweight, they will be in trouble,” Dr. Hagberg said. “The more you weigh, the more the center of gravity moves and the more energy it costs. But in cycling, there are different aerodynamics — your center of gravity is not moving up and down.”
The difference between cycling and running is like the difference between moving forward on a pogo stick and rolling along on wheels. And that is why Robert Fitts, an exercise physiologist at
Even Mr. Hampsten has been surprised by the cycling paradox. He recalls a woman from
“She rode so well,” Mr. Hampsten said. “Her cadence was very efficient. I was just amazed and delighted.”
As for the effects of aging, serious recreational cyclists do slow down, but they are not penalized as much as runners by the passing of years, Dr. Hagberg said. It’s because cycling, while grueling, is not as demanding as running.
“The best example of that, in a bizarre way, is the Tour de France,” Dr. Hagberg said. “What runner could go out six hours a day for three weeks and not be totally trashed after a day or two? That’s a microcosm of the aging issue.”
Still, even the best serious recreational cyclist is almost a different species from a professional rider. How much faster, our touring group asked Mr. Hampsten, would a professional rider go up that 15 percent grade during a race? About twice as fast as the fastest in our group, he replied.
And how about recovery after racing? Mr. Hampsten used to compete in 100 races a year, including the Tour de France, and he would recover by going for a long, relaxed ride. It sometimes took him three hours of cycling to warm up after a hard race. Then he’d continue for another two hours.
But recovery does become a limiting factor for professional cyclists, Mr. Hampsten said. It’s why most professional riders can no longer win long, multiday races after age 32.
“It’s almost eerie that at 32 years, you stop winning,” Mr. Hampsten said. “The endurance seems to stay, but recuperation doesn’t come around.”
When Mr. Hampsten retired, he was 34, “and I hadn’t won a race in two years.”
Now, he estimates, he is 80 percent as fit as he used to be.
But 80 percent for Andy Hampsten is still impressive. As soon as our cycling tour ended, he headed out on a fast ride that included a long hill to the town of
“It is my favorite road to ride,” he said.
