LONDON (Reuters) - Britain\u2019s Mo Farah, who will be running in the London Marathon on Sunday, is in dispute with fellow distance-running great Haile Gebrselassie for failing to help him after he was robbed at a hotel in Addis Ababa owned by the Ethiopian. Athletics - London Marathon Preview Press Conference - The Tower Hotel, London, Britain - April 24, 2019 Great Britain's Mo Farah during the press conference Action Images via Reuters\/Matthew ChildsFarah, third last year and facing a monumental challenge to overcome Kenya\u2019s world record holder and defending champion Eliud Kipchoge in Sunday\u2019s race, said around 2500 pounds ($3,230) - in four currencies - two mobile phones and a valuable watch presented to him by his wife were stolen from a locked suitcase in his room while he was out on a training run on his 36 birthday on March 23. Farah said he got little help from hotel staff in dealing with the issue and even less from Gebrselassie, a national icon in Ethiopia after a stunning track career that earned him two Olympic golds and four world titles over 10,000m and several world records. \u201cHe didn\u2019t respond even though that\u2019s his hotel,\u201d four-times Olympic champion Farah told reporters at the London Marathon launch on Wednesday. Farah was so furious that Gebrselassie ignored his repeated texts and calls that he shared the last he sent, that threatened to publicly shame the Ethiopian. \u201cI want to inform you that I\u2019m disappointed you have not made any effort to find my stolen money, and especially my watch,\u201d he wrote. \u201cI have tried to contact you by telephone several times. Know that I am not responsible for what I say during the press conference in London and what influence it will have on your personality and your business.\u201d He signed off: \u201cSir Mo.\u201d Later on Wednesday Gebrselassie fired back at Farah in a press release, calling his claim of robbery \u201cunproven\u201d. Gebrselassie said Farah declined to use a safe box offered to him or give the money to a hotel official for safekeeping. Gebrselassie, a former world record holder and current president of the Ethiopian Athletics Federation, said the matter was immediately reported to police, who interviewed five hotel employees but decided not to bring charges against any of them. He added that despite a 50 percent discount on the room rate, Farah failed to pay a service bill of 2,313 pounds ($3,000). "I found today's accusations made by Mo with unproven premises, as an act of defamation on my hard earned reputation and business," he said in a release posted on LetsRun.com. here \u201cFollowing this my lawyers will deal with the matter accordingly,\u201d Gebrselassie said. A spokesperson for Farah told the BBC late on Wednesday that he was disappointed with Gebrselassie\u2019s statement. \u201cMo disputes all of these claims, which are an effort to distract from the situation, where members of his hotel staff used a room key and stole money and items from Mo Farah\u2019s room (there was no safe as it was faulty, and Mo requested a new one). \u201cPolice reports confirm the incident and the hotel admitted responsibility and were in contact with Mo\u2019s legal advisor. \u201cThe hotel even offered to pay Mo the amount stolen, only to withdraw the offer when he prematurely left the hotel and moved to other accommodation due to security concerns. \u201cDespite many attempts to discuss this issue privately with Mr Gebrselassie, he did not respond but now that he has, we would welcome him or his legal team getting in touch so that this matter can be resolved.\u201d TASK AT HAND Farah will need all his focus to be back on the task in hand on Sunday as although the race is widely seen as something of a head-to-head between him and the peerless Kipchoge, the Briton is only the eighth-fastest man in the field and his best of 2:05.11 is almost four minutes adrift of Kipchoge\u2019s astonishing world record of 2:01.39, set in Berlin. The Kenyan, who has won 10 of his 11 marathons, including the 2016 Olympic Games, is seeking an unprecedented fourth London win and would need to have something of an off-day to open the door for any of his rivals, but Farah said he was not turning up \u201cexpecting to finish third or fourth.\u201d \u201cYou look up to these guys, you have to learn from the best and I have learned from each race I\u2019ve done,\u201d he said. \u201cI think I could have gone 2.04-something in Chicago (where he set a European record of 2:05:11 while winning last year) but it was about winning the race. \u201cLast year in London when Eliud increased the pace at around 20 miles I went with it a bit but just felt tired and in my mind I felt \u2018I cant keep that going\u2019 and you end up taking it back a notch. But I am here to race and will give 100 percent as I always do.\u201d EXTRA ENDURANCE Farah said he had underestimated the volume of training required to convert his track speed into the extra endurance needed for 26.2 miles on the road, but that he was enjoying the challenge. \u201cThe most important thing is that I\u2019m happy and enjoying it,\u201d he said. \u201cI\u2019m still hungry, I feel like I\u2019ve got my mojo back.\u201d While Farah and Kipchoge fight it out at the sharp end, around 40,000 others will be pounding the streets of London behind them in what organizers say is the world\u2019s most popular race. \u201cWe had 415,000 applications in five days,\u201d said race director Hugh Brasher. \u201cThis weekend we will reach one billion pounds raised for charity by runners, with more than half of that coming in the last nine years.\u201d In the first race in 1981, co-founded by his father and former Olympic gold medalist Chris Brasher, five percent of finishers were female, while this year that figure is expected to be around 45 percent.
