Cycling and Coding Collide at Performance Tracker Strava

At Strava, the idea that “there’s always time for a run or a ride” is more than a motivational motto. It’s a core principle. The San Francisco startup is packed with Type A endurance athletes, people who run five or six miles at lunch and think riding 100 miles is a great way to spend a Saturday.

The 40 or so people shoehorned into a downtown San Francisco office have turned their passion into a business building a social network and performance-tracking tool for cyclists and runners. They work in an office packed with bike gear, and the meeting room is lined with dozens of bib numbers from races employees have competed in. It’s high-energy and hyper-competitive in a friendly way, just like the app.

“Through the sports we do there’s a whole lot of bonding outside of work,” Alex Mather, Strava’s UX lead, said. “It makes the arguments and discussions here a lot easier when you’ve ridden six hours with someone and gone through the crankiness of a long ride. We’re all very Type A, which leads to great discussions because everyone has opinions. We couldn’t survive if we weren’t Type A.”

Strava is more than surviving. It has received $16.1 million in funding and grown from six people to about 40 since its founding two years ago. It has added around 10 people in the past few months. Strava wouldn’t release specific data, but co-founder and CEO Michael Horvath said it is supporting “a few thousand” active users per employee. One day he hopes to hit 100,000 to 200,000.

It’s an ambitious goal, but fitness tracking gadgets and apps are hot right now. The industry is expected to ship 90 million “wearable” fitness trackers like the Nike FuelBand or FitBit by 2017, according to ABI Research. Forrester Research says wearables are the “next wave of consumer technology product innovation,” so it’s no surprise a company like Strava stepped into the market.

“The more people who own smartphones, and the more sensitive those devices become, the more data we have about our bodies and our environments,” Forrester analyst Sarah Rotman Epps said. “Fitness [tracking] is a natural starting point.”

The company’s growth has not been without challenges. Strava was sued last month by the family of 41-year-old William “Kim” Flint, who died while using Strava to track his speed down a fast descent in Berkeley, California. Strava also has been cited in the death of Sutchi Hui, a pedestrian hit and killed in San Francisco by a cyclist accused of speeding and tracking his time for Strava. Horvath had no comment on the lawsuit, and the company has kept mum about the cases.

Strava, like social Garmin Connect, Nike+ and others, lets you record workouts from a GPS device or phone app, then upload it to track, analyze and share. It shows, among other things, where you ran or rode, how long and how fast. You can compare your results over time and rank yourself against others via an online leaderboard. Those posting the fastest times on a particular road or trail win the title King of the Mountain, or KOM.

Strava was born out of a desire by Horvath and co-founder Mark Gainey to create a “virtual locker room.” The two men had rowed together on the Harvard crew team. After graduating and leaving the physical locker room behind, they decided in 2009 to create a site for avid endurance athletes. Strava is currently available as a free web and mobile app, with an option to upgrade to paid premium service. Upgrades are the primary way they’re monetizing Strava.

It’s common to hear people at tech startups say they’re building a product they love and use, but it’s especially true at Strava. If they didn’t work for Strava, they’d be using it. In what may be the best testament to how passionate Strava users are about the product, Horvath said many employees were Strava users before they came to the company.

“Our user base is a great place for finding people,” Horvath said. “If they’re using Strava, then they already know why we’re different. The key is not to say how fast are you, but how passionate are you? How much do you love what you do professionally and how much do you love cycling and running? Most of our staff is passionate about both.”

Strava’s user base is equally passionate. The company’s online forum teems with praise for the product and the support staff, along with suggestions for improvement — like, say, clearing leaderboards of impossible aberrations like someone running a 2:13 mile. Chris Holmes, a product development manager for Electra Bicycle Co., says Strava provides “a reason to push a little harder to go a little bit faster.”

“I’ve always been a numbers geek,” he said. “Strava takes it a step further, with the social aspect allowing me to see where I stand against other users who ride the same routes, along with how and where my friends are riding.”

Beyond the data, Strava’s vibrant social network is a major draw for users like Chris Phipps, who said more than 60 percent of the “200 or so” cyclists he knows in the San Francisco Bay Area use it.

“It’s really easy for us to compare rides and see how much my friends are training,” he said.

Not everyone is convinced Strava is all that. Critics have even created terms like “stravasshole” to describe runners or riders who place their quest to be King of the Mountain above common courtesy. But the Strava team isn’t letting criticism slow it down. Everyone remains pumped and productive.

“It’s kind of that pinch-yourself job, where you say, ‘Wait — I get to ride for two hours, talk about bikes, come into work, and spend the next 8 to 9 hours talking about bikes?’” Mather said. “I just hope and pray that this lasts as long as it can.”

Armor on the Field: The NFL’s Headlong Race to Build the Unbreakable Linebacker

Rob Vito stood at the front of a hotel conference room in Phoenix one day last August, a custom Kevlar vest strapped over his blue dress shirt. Vito is a large man, and the shiny black suit of armor strained to cover his belly. But he wasn’t concerned about fashion, or even looking good. He had a point to make, and wanted to make it with flair.

He raised a carbon-fiber hockey stick over his head, looked out over the 150 or so members of the Professional Hockey Athletic Trainers Society gathered before him and challenged any one of them to whack him with it.

A murmur went through the crowd. People looked at each other. These were professional trainers, and they knew what a shot to the gut could do to a man. But Vito had just spent 10 minutes telling anyone in shouting distance that Kevlar is a miracle material capable of stopping a .44 caliber bullet. Finally, two members of the Edmonton Oilers training staff took the bait.

“Are you serious?” one of them asked from the middle of the room.

“Dead serious,” Vito replied, waving the stick as if to taunt them. “I want you to hit me with this hockey stick as hard as you can.”

One of the men stepped up and hit Vito with a tepid cross-check. Vito didn’t flinch. “Come on,” he barked. “Harder.” The trainer obliged, hitting Vito so hard the stick nearly snapped in two. Vito’s belly shook and quaked as he doubled over. The crowd gasped. But after hamming it up a moment, Vito stood up and roared with laughter.

“Is that all you’ve got?” he asked the trainer. “No wonder you guys lose so much.”

The room erupted with laughter, but the trainers from Edmonton were all business. They placed an order for Vito’s Kevlar pads on the spot.

“If Kevlar can stop a bullet, it can damn sure stop a blitz.”

Vito has been taking a lot of orders lately. He’s the charismatic CEO of Unequal Technologies, a Philadelphia company that manufactures military-grade Kevlar padding for sports equipment. Since 2010, Vito has been touting Kevlar as the best shock-suppression material in the world and boasting that his patented “EXO Skeleton CRT” — CRT for “concussion reduction technology” — absorbs as much as a quarter of the force a player takes to the head or chest, significantly reducing the risk of injury.

“If Kevlar can stop a bullet, it can damn sure stop a blitz,” Vito told Wired.

Over the past year, his pitch has convinced more than 20 NFL and NHL teams to use his pads in their equipment. Two dozen professional players are using EXO Skeleton CRT pads in their helmets, and more than 100 are wearing it in shoulder pads, elbow pads and other gear. As the NHL and NFL grapple with an epidemic of concussions, Kevlar-reinforced helmets are increasingly viewed as a magic bullet. The technology is proving particularly attractive to players who have sustained head trauma and desperately want to keep playing. And later this summer, Vito plans to take his product mainstream, unveiling a multi-million dollar advertising campaign aimed at the hundreds of thousands of youth league players around the U.S.

But in the rush to make their players unbreakable, pro teams aren’t asking many questions of Vito beyond how quickly he can do the job. Neurologists intimately familiar with sports-related concussions warn that there is no scientific evidence that Kevlar can reduce the risk of head trauma. Worse, they fear the pads could make the problem worse by masking symptoms. The leagues have yet to independently test the effects of Kevlar, and neurologists – including one who has treated many concussed NFL and NHL players — expressed surprise when told it was being installed in helmets.

“We need to look at this scientifically and come up with some process of examination on whether this works,” says Dr. Michael Collins, director of the UPMC Sports Medicine program. “At this point in time, to my knowledge, I don’t know of a fully controlled study that shows the effectiveness of [Kevlar] in mitigating the instance or severity of concussions.”

Unequal Technologies claims its patented Kevlar-reinforced pads reduce the the G-force generated by an impact by as much as 25 percent, reducing the risk of concussion. “If you opened up a soldier’s equipment, you’d find the same stuff we’re using in our gear,” company CEO Rob Vito says.

Soccer Finally Comes to Its Senses With Goal-Line Tech

Soccer has finally come to its senses.

After years of discussion and debate, the sport has at long last approved the use of goal-line technology at all levels of the game. Thursday’s decision by the International Football Association Board will all but end flubbed calls that have decided games as monumental as the World Cup final and made the sport look embarrassingly Jurassic in a hyper-connected age of instant replay and instant communication.

The IFAB approved systems made by the British firm Hawk-Eye and the Danish-German venture GoalRef. Both have been extensively proven in tests with ball cannons and mannequins before being thoroughly shaken down in matches. The two systems alert a referee within one second when a ball has crossed the goal line, eradicating absurd blunders like Frank Lampard’s phantom goal for England in the 2010 World Cup finals against Germany, which was clearly over the line yet still disallowed.

We’ll see the tech on the pitch as early as December in the FIFA Club World Cup and in most major leagues beginning next year. And it’ll definitely be in place for the 2014 World Cup. FIFA, the sport’s governing body, at first opposed the tech but abruptly changed course after the England vs. Germany blunder.

“Today is a historic day for international football and for the IFAB,” FIFA President Sepp Blatter said in an interview published on the FIFA website. “It’s a very modern decision to apply this to football. It is so important because the objective of football is to score goals. With the new techniques and the new tactics, it’s difficult to score goals, so it helps to use technology to help identify when a goal is scored. It’s a help to the referee. There was a call for this technology and now I can say that we did it.”

It’s long past due.

In Elite Swimming, Paddlers Are More Efficient Than Propellers

Recreational swimmers don’t think too much about the precise arm motion that maximizes efficiency and power. Most are simply trying to stay afloat and moving. But elite freestyle swimmers like Kara Lynn Joyce or Michael Phelps have long pondered the ideal technique. Some use what’s called deep catch, pulling their arms through the water like a paddle. Others use sculling, which involves swinging the arms to the side like a propeller.

Both are used by Olympic-level swimmers, but a research team at Johns Hopkins University has crunched the numbers and says the deep catch has the edge. It produces more thrust, said Rajat Mittal, a fluid dynamics expert, mechanical engineer and professor at Johns Hopkins’ Whiting School of Engineering. Sculling is about 20 percent less efficient, an astronomical difference in an event where fractions of a second matter.

“While the fact that the deep catch is more effective than sculling might not have been a complete surprise,” said Mittal, “the surprise was that first, sculling does not really do what it is supposed to do, which is to produce more lift-based thrust, and second, that the deep catch actually generated a majority of its thrust from lift and not drag.”

‘Blade Runner’ Oscar Pistorius Dashes Into Olympic History

South African sprinter Oscar Pistorius is headed to the Olympics, a historic event almost certain to validate the double-amputee’s quest to be considered “a runner,” not a “disabled runner.”

The 25-year-old will run for the South African Olympic team, making him the first amputee to run in both the Olympic and Paralympic games. In what is sure to be one of the big draws of the Games, Pistorius — whose legs were amputated below the knee before he was 1 year old — will run in the individual 400 meter race and the 4×400 meter relay in London.

“Today is truly one of the proudest days of my life,” Pistorius said in a statement after being named to the team Wednesday. The statement followed an exuberant tweet he sent after the South African Olympic committee included him among the 125 athletes it is sending to London.

“Will be in @London2012 for both the Olympic and Paralympic Games!” he tweeted. “Thank you to everyone that has made me the athlete I am! God, family and friends, my competitors and supporters! You have all had a hand!”

His spot on the team fulfills a dream Pistorius has chased since at least 2007, when the man called Blade Runner first ran against able-bodied runners at the international level. Pistorius has over the past five years honed his skills and performance, competing at the world championships last year in South Korea. He is among South Africa’s most notable athletes, both for his speed and the J-shaped carbon-fiber prosthetic blades, called Flex-Foot Cheetahs, that work something like a cat’s hind legs.

“This is an intriguing moment in the history of the science of sports,” said Dr. Matt Bundle, a University of Montana professor who co-authored a study about Pistorius as part of the runner’s appeal after being banned from Olympic qualifying in 2007. “An individual is able to use a mechanical device in a way that surpasses the human leg. It’s an important time to note that that’s impressive.”
