A team of 20 marathoners will represent Botswana at the Southern Region Cross Country competition pencilled for Zambia on February 23. The runners have been selected during some national meets. The team will depart on February 20 and return on February 25. Bobby Gaseitsiwe, the senior sports development officer for the Botswana Athletics Association (BAA), said the competition -- sponsored by Botswana Development Corporation -- would be used as a yardstick to qualify for World Cross Country championships slated for Scotland on March 30. It is their challenge to excel during the Zambian meet as that will definitely book themselves place to the world meet, he said. Gaseitsiwe said if the athletes run good times at any of the competitions, they will qualify for Olympic Games. He said BAA was hoping that Leamile Radimpa, who will be taking part in the Standard Chartered Greatest Race on Earth final leg in Hongkong on February 16, will qualify.
