DURBAN, (Reuters) - South Africa's Olympic swimming champion Chad le Clos remains undecided on the intensity of his Rio de Janeiro Games schedule ahead of a much-anticipated showdown with idol and rival Michael Phelps in Brazil.

Le Clos stunned the American with victory in the 200 metre butterfly at the London 2012 Games and this week booked a spot in five different events in Brazil after securing required qualifying times at the South African swimming championship.
