When BBC Sport tried the 'whereabouts' drugs

Nine UK athletes, including Mo Farah, missed drug http://www.seahawksofficialnflonline.com/WOMENS_YOUTH_TYLER_LOCKETT... tests in the year before London 2012, it has been claimed.
After the Daily Mail reported double Olympic gold medallist Farah failed to hear the doorbell when UK anti-doping (Ukad) officers called at his house, a number of his Great Britain team-mates told BBC Sport of their near-misses.
Olympic medallist Kelly Sotherton and 800m runners Jenny Meadows, Michael Rimmer and Lynsey Sharp all attested to how strict the requirements of the 'whereabouts' system are.
Sharp revealed how she spent one hour a day in a Boston cafe while on holiday for two weeks because the rented apartment doorbell didn't work, while Rimmer even suggests athletes are tagged to make it easier for the testers.
So how easy is it to miss a random drugs test? The BBC's chief sports writer Tom Fordyce recalls his month on the 'whereabouts' system...
You might think it was impossible. So did I. Which was why, back in 2011, I began a month-long experiment in which I was added to something called the National Registered Testing Pool.
This is the controversial heart of the fight against doping, the 'whereabouts' system that UK Anti-Doping uses to keep track of the country's 400 or so elite Olympians. Each athlete must specify where they will be for an hour a day, seven days a week, for three months in advance, as well as where they will be training each day.
If it sounds draconian, there is logic behind Ty Sambrailo Youth Jersey the imposition. Out-of-competition testing is far more likely to catch cheats than tests only taken at big events. To be effective, these tests must be unannounced. Hence the need to specify a window of opportunity.
Being someone who considers themselves relatively organised, I could envisage few problems doing it for just four weeks. That was to underestimate the detail required and the intervention of the real world.
On a computer programme called Adams (Anti-Doping Administration and Management System), each athlete must submit a mountain of information: their residence for every day in that month, whether home address, hotel or friend's house; their full training schedule for every day; where they will be competing - dates, venues, times - and where and when their one-hour slot will be.
The programme itself looks a little like Microsoft Outlook, albeit initially less intuitive and a little more fiddly. There is a clickable daily calendar, contacts section and area for direct messages.
Each athlete has access to a support officer who is available to help them 24 hours a day. This quickly becomes essential, because everything takes time. For every address you might stay at overnight you have to input full details - not just the name and street, but specific instructions - ring top doorbell, blue door on left, code for front gate etc.
If you spend your entire life in one place it wouldn't take very long. But sportsmen don't. Neither do sports journalists. In that month I was due to be in Southampton to cover cricket, Wimbledon for the tennis, some friends for a weekend away, a stag-do in London and a hotel or two for other work trips. That's a lot of addresses.
Then there are the spontaneous complications.
One morning my mum called, inviting me over for Sunday lunch. Among the things to remember when visiting home (flowers, better manners), emailing the drug-testers to give them her address did not come naturally.
So much for the theory. When the http://www.nflcowboysofficial.com/Authentic-Chaz-Green-Jersey testers actually came, I almost missed them.
Having worked until the early hours and been up in the night to comfort my then-three month old son, I slept right through the 6.30am doorbell.
Only my partner heard it. Had she too missed it, or had chosen to ignore it and stay in bed rather than opening the door, the DCO (doping control officer) would then have tried again every quarter of an hour.
My mobile was out of action, turned off in the hope of a lie-in. The DCO could not have called it anyway. Testing cannot be done without warning if your phone alerts you first.
Had I failed to respond to the doorbell's nudges for duration of my specified hour, it would have been logged in the system as a missed test.
