Osano competed extensively around the world in the 1991 season. In May he had wins at the Great West Run in England, as well as at the Bay to Breakers and Bolder Boulder in the United States.[4] At the Bislett Games in Norway in July he recorded a lifetime best of 27:28.87 minutes for the 10,000 m. Although this only brought him third at the competition, it made him the fifth fastest runner over the distance that year.[5] He was selected to represent Kenya on the track at the 1991 World Championships in Athletics. His compatriots Moses Tanui and Richard Chelimo took the top two spots in the 10,000 m. Osano's plan was to disrupt the running of the (highly favoured) Moroccan Khalid Skah and though the tactic was successful for his teammates, Osano finished behind Skah in fourth.[6][7][8] Two weeks later he ran the same distance at the Memorial Van Damme, taking second behind his more experienced Kenyan rival John Ngugi.[9] He finally topped the podium in the event at the All-Africa Games later that month, beating fellow Kenyan William Koech by a narrow margin.[10]
Osano was dominant in Japan in the first half of 1992, going unbeaten with wins including the Chiba International Cross Country and Shizuoka International. He also had repeat wins at the Bolder Boulder and Bay to Breakers in the United States.[4] Osano finished third at the Kenyan Olympic trial race for the 10,000 m, but in a controversial decision the selectors decided instead to send Moses Tanui, who had failed to even complete the distance at that race.[11] His Olympic debut thwarted, Osano did not compete again in 1992. He returned to action in May 1993 and headed to the American road circuit, taking wins at the Peachtree Road Race, Boilermaker Road Race and Bix 7 Road Race. Given his form, he was chosen for the Kenyan team at the 1993 IAAF World Half Marathon Championships.[4] This was his only half marathon that year and he placed thirteenth in a time of 62:10 minutes, helping the team to victory with the help of fourth-placed Lameck Aguta.[1] This proved to be his final international appearance.[4]
Later career and decline
He began 1994 with a win at the Fukuoka International Cross Country and then moved on to American road races, though he was less successful on this occasion and his best results were runner-up placings at the Azalea Trail and Cherry Blossom 10-Miler. He ran in Europe in the second half of the year, but again was one place short of the top at the Dam tot Damloop, Route du Vin Half Marathon and Paris 20K. He made his marathon debut at the New York City Marathon in November, but his time of 2:18:43 hours was not impressive and left him in 14th place. He ran at shorter distances the following year and won the Crim 10-Miler, Breda Singelloop and the Brussels 10K. A runner-up finish in 60:36 minutes at the Route du Vin race was a lifetime best for the half marathon event.[4]
Osano ran in no less than 27 road races in Europe and the United States in 1996. These took in wins at the CPC Loop Den Haag, Parelloop (a career best for the 10K run at 28:02 minutes), Bay to Breakers, Tilburg Ten Miles and Route du Vin Half Marathon. He had a similarly planned 1997, but had less success, his sole win coming in Tilburg (though he was the Falmouth Road Race runner-up). He made his second outing in the marathon in Amsterdam that November, but his run of 2:23:31 hours was even slower than his last. His performances declined in the 1998 and 1999 season and he generally placed outside the top five of his races. Despite being only 29 years old, he retired from competition.[4]
