The Olympics would not be the Olympics without some controversy over perceived advantages for certain nations.
At the 2018 Winter Olympics in Pyeongchang, perhaps the first controversy has come over Great Britain's skeleton suits.
On Monday, The Guardian's Sean Ingle reported that Great Britain hopes to medal in skeleton — the women's team has two gold medals in the last two Olympics — thanks to "revolutionary skinsuits that have helped british Cycling to dominate the last three summer Games."
According to Ingle, the suits have "special drag-resistant ridges" that reduce the amount of wind resistance racers experience. Riders believe they can benefit by as much as one second — a huge margin in skeleton — because of the innovations.
On Monday, during practice runs, Great Britain appeared to have a great advantage, as Ingle pointed out. Several riders on Britain's team, both men and women, posted top times, including some first-place finishes. Afterward, some other riders expressed skepticism.
"I'm not a scientist," U.S. skeleton racer Katie Uhlaender said (via Tim Reynolds of The Associated Press). "I just know that I was trying to get a suit of the same quality and I was told that it was illegal."
Germany's Jacqueline Loelling, who is a gold-medal favorite, told the AP: "I don't know what they have really for suits. But I think every athlete has a secret."
"People are going to try different stuff and the rule book has some gray area," Kendall Wesenberg of the U.S. said.
The International Bobsleigh and Skeleton Federation said in a statement that Britain's suits complied with the rules.
According to Reynolds, the US-Britain rivalry goes back several Olympics. When Britain's Amy Williams won gold in skeleton in Vancouver 2010, the U.S. and Canada protested, believing her helmet didn't meet the sport's standards. Additionally in 2014, a British-led protest disqualified American skeleton racer Noelle Pikus-Pace from a World Cup win for having tape on her sled handles.
There are other theories about Britain's suits — some think the talk of the suit innovations is to throw off the competition.
"A large part of this sport is mental strength," USA Bobsled and Skeleton CEO Darrin Steele told Reynolds. "It's about who can throw down despite distractions, and we'll see who comes out on top over these next few days. The timing of the article was perfect and a smart strategic move by the british team."
The british racers, however, wouldn't bite on any controversy.
"People can speculate as much as they like," british rider Jerry Rice said."The fact of the matter is the british guys are fast because we're good at sliding, no other reason. We're innovators, we do everything we can to be as fast as we can be."
No one would be shocked to see Britain medal in the skeleton, but if they do, it may raise more questions about their methods.
