33 sportsmen and women have been suspended by the Anti-Doping Agency of Kenya for violating anti-doping rules.
The anti-doping organization sanctioned 26 athletes, including defending Amsterdam Marathon winner Joshua Belet.
Belet, who led a Kenyan 1-2-3 finish to win the Amsterdam Marathon in October, was suspended due to Anabolic Androgenic Steroids, Testosterone, Adiol, Pregnanediol, and Androsterone, and Etiocholanolone.

Belet won in 2:04:18, the third fastest time ever recorded in the Dutch capital, beating his compatriots Cyprian Kotut and Bethwell Chumba.
Other prominent names on the list include former Kenya Sevens fly half-master Brian Wahinya, 2012 World Under-20 5000m winner David Bett, rising sprinters Duke Osoro and Joan Jeruto, and basketball stars Alex Ramazani, Albert Onyango, and James Mwangi Maina.
Kenya's Paris-bound competitors must take at least three anti-doping tests by July 4 in preparation for the Summer Games, with the first test deadline falling on May 3.
The anti-doping organization ascribed the largest number of offenders to increased testing among Kenyan athletes and women.
