"You can be a junior forever. That is why some athletes fail to heal from injuries on time due to wrong medication based on their falsified ages," said Tuwei.
Tuwei said warned some Embassies in the country, who have cleared athletes to compete outside without clearance from Athletics Kenya.
Tuwei explained that their office is always ready to assist athletes who have no managers.
"We are ready to stand in for any athlete but they should be straight with us. We shall not handle anything beyond athletics activities," said Tuwei.
Tuwei once again advised the athletes to save and invest wisely since the life of an athlete on track is short.
The 2008 Beijing Olympics 800m champion Wilfred Bungei and All Women's World marathon record holder Mary Keitany gave talks on the pre and post challenges in athletes life.
Bungei gave a moving testimony on how he has managed to recover from alcoholism that almost ruined his life upon retiring from athletics in 2010.
Bungei has since not taken alcohol for the last seven years.
"There was a big vacuum in my life upon retiring in 2010 since I had nothing else to do. I lived 365 days annually as an athlete with no social life. It took tall one me after I retired hence resorted to drinking," said Bungei.
"On the night the 2008 Olympic marathon champion Samuel Wanjiru died, I was admitted in hospital owing to alcoholism having drunk many litres of wine and vodka."
Keitany advised athletes to avoid fake coaches and doping.
