PBS高端访谈:今年的“环法自行车赛”变成虚拟骑行（在线收听）

Sreenivasan: For more than 100 years, the middle of the summer has signaled the Tour DeFrance annual bike race across France. This year, due to the pandemic, the world's mostwatched bike race is delayed. But there is a heavily watched virtual one going on everyweekend.

We look down then on the avatars of the riders in this virtual Tour De France.

Sreenivasan: World class bike riders and teams are racing against each other on their ownbikes at the same time often from their homes, and the world is watching them bike and playwhat looks like a video game. I recently spoke with Eric Min, the C.E.O. Of Zwift, the companyenabling this virtual tour, and racer Lauren Stephens, a professional cyclist who recently wonthe second stage of the virtual Tour De France.

As they make their way across the line, who takes it? It looks to me like Lauren Stephens Ithink may well have taken the stage.

Sreenivasan: First of all, congratulations. You're a winner of this stage of the Tour De France. You don't get to say that very often. Most people don't understand what's happening here. You're riding in Dallas, Texas, where you are now, and you're competing in a virtual race. Howdoes this work?

Lauren Stephens：So, our bikes are set up on what we call a Trainer.

Sreenivasan: Think of it like a treadmill for a bike.

Lauren Stephens: And what that does is give the resistance to our bike. So if we go up a hill, it's going to put more resistance on our bike. And if we're going downhill, we'll get lessresistance.

Sreenivasan: So everybody is feeling the hills, so to speak.

Lauren Stephens:Right. The other component is at the crank of our bike where we pedal itmeasures our output.

Sreenivasan: So there's basically a video game representation of you riding in a race againstvideo representations of everyone else. This has to take some getting used to considering whatyou grew up doing was riding a bike against real people in the real world.

Lauren Stephens:Yeah, it's definitely a lot different than riding outside.

Sreenivasan: Riders are racing from all over the world at the same time, some from NewZealand at 2:00 in the morning, many from their basements or garages. You can see how hardthe riders are working, how many watts their legs are generating and how fast their hearts arebeating to do it.

Lauren Stephens:You can't feel your opponents, can't see if they're getting tired or if they'reslowing down. Everyone's avatars, you know, are look happy and fast and full of energy. So, it'sa lot of internal motivation in your living room. The other thing on Zwift is you're pedaling 98% of the time where outside, you know, you go down a hill or you're coming to a stop, like, you ease off. But on Zwift, you're pedaling all the time.

Sreenivasan: Virtual racing means Stevens has had to learn a thing or two. When you got onthis platform, you were competing against people who are not pros, but are still pretty good.

Lauren Stephens: When I first got onto the platform there's people I've never even racedoutside or they haven't even raced outside and they're racing on this virtual platform. And atthe beginning, you know, they're beating me. And I had a lot to learn. So this was a newdiscipline for me, and I think I've figured out a lot of it now.

So they all use some power ups and Lauren Stephens is the winner of that stage.

Eric Min:We have the liberty of doing something you can't do in the real world, for example, having these special powers.

Sreenivasan: This is Eric Min, the C.E.O. Of Zwift, the company that connects all the biketreadmills together.

Eric Min: You can go through different gates within the circuit of our maps and collect theserandom power ups, and they can make you faster for a short period of time. They can makeyou lighter. In other cases it takes away the ability for the riders behind you to take advantageof your draft. And sometimes you can go invisible for ten seconds and you have to use thesepower ups very strategically. So, if you know how to play the game, you have a hugeadvantage over someone who thinks they're just strong. So just being strong is not enough todo well on Zwift.

Sreenivasan: How many people are watching this virtual Tour De France on television?

Eric Min: We have 20 broadcasters around the world covering about 140 countries. The samebroadcasters that would have covered the Tour De France during the month of July is coveringthe virtual Tour De France. So it's in the millions.

Sreenivasan: So, millions of people are watching what looks like a video game play out. What, what are you learning from that?

Eric Min: The fact that you can, you know, compete on a global scale from the comfort ofyour home. The fact that there's no travel and time wasted to get to your events. On balance, it's an incredibly affordable, accessible global sport that we're creating.

Sreenivasan: You know, we talked to Lauren Stevens this morning, but, you know, one of thethings that is hard to replicate is being able to figure out whether that rider next to you isgetting tired or not. Whether they look like they have more in their legs or whether maybe youshould try to pass them now, because this is it. They're weak. They're on the ropes.

Eric Min: We're not trying to replicate outdoor, you know, riding or racing, we're trying tocreate a whole new version of it. It's not a six hour bike race. It's a one hour race that's muchmore intense. As a viewing proposition it's much more dynamic and exciting.

Sreenivasan: Unlike the real Tour De France, where women only compete in the last stage, these virtual race days all have women's races, same courses, same difficulty. It's somethingboth Min and Stephens see as a positive sign. Lauren Stephens still has stages left to race inthis year's virtual tour. We wish her well. Last night's women's race was won by Tonja Erath, adoctor from Germany who became a professional cyclist by winning a competition throughZwift Academy.
