The 17-year-old completed a prodigious rise in 2011 with an unexpected win over the imperious David Rudisha in Milan. If anything, burn-out could turn out to be a greater threat to Aman than any track rival - he travelled extensively last year (running on four continents) in a season that stretched from May to September.
Interestingly, Aman mentions that diet was a bit of a hurdle as he struggled to get the right balance of nutrition for a middle-distance runner. Perhaps Ethiopian athletes could benefit from looking at the differences between their national cuisine and that of Kenya - which is more inclusive of rich starchy foods such as cassava, yam, and sweet potato (although enset - or false banana - seems to be a staple in some areas of Ethiopia).
For next year, Aman is looking to run at the three main championships open to him - World Indoors, African Outdoors, and the Olympics. The men's 800m is sure to excite in London!
