Inside the new anti-doping system
Every Olympic athlete representing Great Britain this summer is using it, it's the cornerstone to every sport's fight against drug cheats, and it's just changed significantly.
This is Adams (the Anti-Doping Administration and Management System), the online program that athletes use to tell the testers where they will be for an hour a day, seven days a week, and where they'll train at all times.
When I signed up to the National Registered Testing Pool last summer, in order to experience first-hand what our sporting heroes go through, I found the old version of Adams clunky, slow and impossible to access from your phone. You got the hang of it with time, but it was far from simple.
With the new system freshly in place ahead of the London Olympics, I decided to test it out myself.
The old Adams looked a little like a very old version of Microsoft Outlook. The new one looks like an up-to-date one - easier on the eye, easier to use and harder to make accidental errors on - which, considering that three missed tests can lead to a ban from all Olympic competition, is about as grave an administrative error as any athlete could ever make.
Eighteen months in development from Wada (the World Anti-Doping Agency), it has one instant advantage over the version it replaces: any date or action that needs your attention shows up red. Any detail you've successfully updated comes up green.
It might not sound like much. But when you're inputting three months of detailed information at a time - addresses of your home, your partner, your parents, any hotel you might stay in, training centres, race venues, physio appointments - every tiny piece of assistance is welcome.
This time, there is also an in-built user guide. Before if you wanted to make a last-minute tweak to your hour to reflect a change to your training time, you had to phone UK Anti-Doping or your sport's own experts. Now you should be able to do it yourself, wherever you are in the world.
One of the biggest complaints from athletes was the issue of specifying where you would be for that hour while on the move. Those flying to competitions, for example, often had to input the airline, flight number and seat number, and add in somewhat caustic comments like 'OVER THE ATLANTIC'.
The new system fixes that. Now you can input a day as 'TRAVEL', and a blue 'AIR' signifier with an airplane icon will appear on that date in your Adams calendar. If the flight is delayed, you can text an update in from the departures or arrivals lounge.
How well is it working?
Speaking to anti-doping officers at various Olympic sports, a number of recurring themes emerged. While almost all prefer the new system, there remain a number of key concerns.
If an athlete enters a new overnight residence into a date on the in-built calendar, for example, the programme takes that to mean they will be there that morning, rather than that night and following morning - an illogical oversight that could lead to a missed test.
There is still no smartphone app. Although Wada promise one is being developed, it certainly won't be ready for this summer's Olympics.
While you can access Adams through the browser on an iPhone, it won't work at all for BlackBerry users. Should you update your whereabouts with a text message - as many athletes regularly do - you still don't require a password, meaning that anyone with access to your phone, could alter your personal information. And any update you do text in will reach UK Anti-Doping but won't appear in your own online diary.
Neither is it quite as universal as Wada would like.
One of the many interesting nuggets to come out of the Tackling Doping in Sport conference in London last week was that Qatar's national anti-doping body has decided not to implement ADAMS because of trenchant athlete opposition to home testing.
So how are British athletes finding it?
The early signs have pleased UKAD. From 400-odd sportsmen and women in the testing pool, there were less than a handful of missed submissions in the first quarter.
"It is so much better than the old one," says Jeanette Kwakye, British 100m champion and Olympic finalist in Beijing.
"There were times with the previous version when I would be typing in my whereabouts info at one in the morning. I couldn't get my head round it.
"There are still one or two little things that aren't perfect, but now it's a couple of clicks and you're done.
"The next thing I'm desperate for is the app. Everyone is on smartphones. I can understand the security issues, but we travel so much - changing venues, changing training times - that it's so important to be able to update on the move.
"But I'm a massive fan of testing. It protects the sport I love. This system isn't convenient, but everyone in office jobs has paperwork, so us athletes shouldn't be any different. We go really hard to make it work for us."
And what of the whereabouts system itself, famously dubbed "draconian" by Andy Murray? At the same conference in London, I shared a platform with Ian Smith, legal director of the Professional Cricketers' Association, during a discussion about the ethics and legality behind it all.
"What we need to know is whether no-notice out-of-competition testing is even effective," said Smith.
"This is where there is a gigantic hole. It is definitely perceived wisdom that, if someone will cheat, they will do it at home. I'm not saying that is not the case, but we have no evidence because the reporting provided to WADA is simply not happening. The lack of statistical evidence is alarming.
"The whole system is weighed in favour of the police and against the athlete. Who does this system exist for?
"Why is it for the athlete to prove that there isn't one (intention to cheat)? A man can commit the most heinous crime in front of the world, on television, and he still gets a fair shot at trying to prove he is not guilty. The same does not apply to athletes just trying to make their living."
