The U.K. anti-doping agency has sent investigators to Kenya to look into allegations that four British athletes used the banned blood-booster EPO in a well-known high-altitude training region, claims that could increase the scope of the problem in the East African nation and show foreign runners are also doping there.The allegations, made using secretly filmed video footage in a joint sting operation by German broadcaster ARD and British newspaper The Sunday Times and published late Saturday and early Sunday, were of grave concern and of significant interest, UKAD CEO Nicole Sapstead said.We have opened an investigation and are taking the necessary steps to corroborate the evidence and investigate it further, Sapstead said in a statement. I can confirm that this evidence is being treated with the utmost importance and urgency, and two members of UKAD staff are currently in Kenya pursuing a number of lines of enquiry.The four British athletes accused of doping with EPO in and around the British teams high-altitude training camp in Iten in western Kenya were not named, although The Sunday Times said it knew the identity of at least one of them and that the athlete was already under suspicion for doping.The two media outlets said three Kenyan men -- two of them doctors at a hospital in Eldoret, another high-altitude running town near Iten -- told them that they had either provided or administered EPO to four British athletes. Two of the Kenyan men implicated by the reports were arrested last week by Kenyan anti-narcotics officers and appeared in court on doping-related charges.Kenya has been under severe scrutiny over the past four years because of a surge in doping cases involving its runners. Kenyas high-altitude training camps are popular with top distance runners from across the world, raising concerns that foreign athletes could also take advantage of the areas poor doping controls.ARD and The Sunday Times reported they quickly found an EPO supplier in Iten. Using a hidden video camera, ARD and The Sunday Times secretly recorded the supplier saying he could easily provide EPO for around 60 Euros ($66) a dose.The media outlets reported they found empty EPO packaging matching those the supplier offered them, along with used syringes, in a garbage can at Itens nearby High-Altitude Training Center. At the time, a number of European athletes -- British and Turkish -- were in attendance.We strongly suspect doping in this Olympic year, the ARD reporter said.EPO is a hormone that boosts the number of oxygen-carrying red blood cells and can therefore increase an athletes endurance. It was the banned substance at the center of the Lance Armstrong doping scandal in cycling.One of the Kenyan men who allegedly provided the EPO to British athletes, identified as Joseph Mwangi, said in the sting that he had supplied the substance to around 50 athletes in all, some of them Kenyan and some foreigners training in Kenya.The allegations appear to reflect the overriding problem in Kenya, where men claiming to be doctors or pharmacists have for years been supplying banned substances for cash. World 1,500-meter champion Asbel Kiprop of Kenya, who has not been implicated in any doping, said last week that in one case Kenyan authorities had taken no action after a marathon runner banned for doping identified the doctor who supplied him with steroids.

ESPN looks at the potential strategy options for the Brazilian Grand Prix.Wet weather on race day morning means the teams slick-tyre strategies are likely to go out of the window. After a scorching hot Friday the teams understanding of the tyres at Interlagos is skewed given the 17C air temperature on Sunday morning, but the forecast is likely to mean the intermediate and full wets become the tyres of choice.On the off chance it does dry up ahead of the start of the race, the key to all strategies will be finding the balance between using the soft and medium tyres over a two-stop strategy (the hards are essentially redundant here, unless you are trying a one-stop).Pirelli recommends that the following numbers of laps are not exceeded on each compound:Hard = 38 laps Medium = 35 laps Soft = 18 lapsAnd on this basis, the possible pit-stop strategies predicted by Pirelli are as follows:QUUICKEST Three-stopper: 3 stints on soft of 15 laps + 1 stint on medium of 26 lapsSECOND-QUICKEST Two-stopper: 1 stint on soft of 15 laps + 2 stints on medium of 28 lapsSLOWEST Two-stopper: 1 stint on soft of 15 laps + 1 stint on medium of 26 laps + 1 stint on hard of 30 lapsAlso possible One-stopper: 1 stint on medium of 33 laps+ 1 stint on hard of 38 laps It was telling that none of the teams used intermediate tyres during the damp start to final practice and instead opted for the unfavoured full wets.dddddddddddd This was a strategy to save all four sets as inters for the race in the event that the conditions are mixed, while still having two sets of new full wets available. Should the track dry out, the drivers have the following slick tyres available. ' ' '
