“Some women refuse to be a slave of routine,” said in 1962, the year Beryl Swain entered the race. “Mrs. Beryl Swain not only works an office job and holds down a home, but has an unlikely hobby—motorcycle racing. And,” says the announcer, with some muted astonishment, “she’s good at it!” As good as she was, she was only allowed to do it once.

Swain was a pioneer in the iconic, dangerous, 38-mile motorcycle race that has claimed the lives of hundreds of competitors over the years. She would have competed again, and she could have honed her skills, but it was that risk—and the risk of organizers looking bad if a woman was killed—that kept her from racing in it again, right in the midst of her enthusiasm.

“Women, the weaker sex, are muscling in on man’s domain, practically no sport is sacred,” at the time.

In 1952, then-Beryl Tolman was a secretary at a shipping company when she met Eddie Swain, a motorcycle racer who ran his own shop. The two fell in love. They were married in 1959, and from the beginning, prepare his bikes for races all across England. One can imagine it did not take long for him to convince her to swing a leg over a motorcycle.

She found the experience exhilarating. Soon, she was entering races at Snetterton and Brands Hatch, in the small and maneuverable 50cc class, though she tried out some 500cc motorcycles. At Brands Hatch, she nearly broke the lap record for the much smaller-engined 50cc motorcycles.

“This was my first try for six months and my hands were frozen round the twistgrip,” , “but I was told I had managed to get within three seconds of the lap record for 50 ccs.”

Alongside , and —the first woman to round the Isle of Man TT course as a racer, in 1958—Swain was part of a precious few women in the sport, competing in a time when motorcycling wasn’t considered “ladylike.” Her status as the first solo female rider garnered attention and admirers. She was tough, glamorous, indefatigable.

“I have been doing all I can to give lady riders as much publicity as possible,” she continued to the newspaper, just before she was due to compete. “Pat is not able to have an International License, and I believe that Margo is a little undecided at the moment.”

The Isle of Man Tourist Trophy is . Nearly 38 miles takes one nearly around the entire isle, through fast sweeping corners to dizzying elevation changes, climbing from sea level to 1,300 feet, through the mountains and through the streets of the town of Douglas. Since the race was first run in 1907, there have been 246 competitors killed, either in practice or in the midst of competition.

At a certain point, you stop being shocked by how many people have died here. The shock is how many

Swain entered the Ultra Lightweight class with a 50cc , an Italian motorcycle too obscure to be resurrected. This time it was her husband setting up her bike. She wore a bright patterned sweater over her leathers. Out of 25 entrants in her class, she placed 22nd.

And she loved it. She announced that she would be back next year to compete again.

But the International Federation of Motorcycling revoked her international racing license. Their excuse: the death of a female rider around the deadly Isle of Man TT circuit would make for bad press. “Having a male racer injured or killed on the TT course was one thing,” said , curator of social history for the Manx National Heritage. “But the organizers were just not prepared to take the risk of that happening to a woman.”

Swain was able to rally support from fellow racers, from her fans, and even the Lieutenant Governor of the Isle of Man, to no avail. More people wanted her gone than to come back next year. She went home and hung up her leathers for good.

A woman rider would not race at the Isle of Man TT again until 1978, when started her career with Yamaha, often competing against her husband, John. (Her daughter Gail is the only woman to ever average 100mph on a 125cc motorcycle around the course.) In 2009, Jenny Tinmouth broke the lap record in her first-ever entry at the TT. The next year, she came back and . That same year, became the first woman to win a class around the circuit, winning the ultra-lightweight class—the same class in which Swain rode.

After Swain stopped riding she went to work for the British grocery chain Sainsbury’s, managing multiple locations in and around London. She retired quietly to Essex, volunteered for various women’s charities, and died of in 2007. In 2009, the Manx Museum unveiled an exhibit called “,” which placed Swain back in the spotlight.

“People ask me what I enjoy about racing,” , “and I usually tell them—speed.”
