Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

Returning to a book you’ve read many times can feel like drinks with an old friend. There’s a welcome familiarity - but also sometimes a slight suspicion that time has changed you both, and thus the relationship. But books don’t change, people do. And that’s what makes the act of rereading so rich and transformative.
The beauty of rereading lies in the idea that our bond with the work is based on our present mental register. It’s true, the older I get, the more I feel time has wings. But with reading, it’s all about the present. It’s about the now and what one contributes to the now, because reading is a give and take between author and reader. Each has to pull their own weight.
There are three books I reread annually .The first, which I take to reading every spring is Emest Hemningway’s A Moveable Feast. Published in 1964, it’s his classic memoir of 1920s Paris. The language is almost intoxicating (令人陶醉的)，an aging writer looking back on an ambitious yet simpler time. Another is Annie Dillard’s Holy the Firm, her poetic 1975 ramble (随笔) about everything and nothing. The third book is Julio Cortazar’s Save Twilight: Selected Poems, because poetry. And because Cortazar.
While I tend to buy a lot of books, these three were given to me as gifs, which might add to the meaning I attach to them. But I imagine that, while money is indeed wonderful and necessary, rereading an author’s work is the highest currency a reader can pay them. The best books are the ones that open further as time passes. But remember, it’s you that has to grow and read and reread in order to better understand your friends.
