Bangladesh's first-ever Olympics qualifier Siddikur Rahman and swimmer Mahfizur Rahman Sagor will begin their Rio campaign today on day six.
Siddikur Rahman will tee-off in the opening round at the Olympic Golf Course at 4.30pm (Bangladesh Standard Time) while Sagor will participate in the heats of men's 50m freestyle event at 10pm BST.
Since Bangladesh made their Olympics debut 32 years ago, they have remain the most populous country in the world never to win a medal in the mega event. If there is the slightest hope for Bangladesh in Rio to end the drought, Siddikur is their only realistic chance.
The 31-year-old golfer will battle among 60 participants. Although the men's individual golf event is getting underway today but Siddikur's fate, if he can make the cut, will be decided on August 14 after the end of the fourth round.
Before leaving for Rio, the two-time Asian Tour winner termed his Olympic debut as his best achievement of his life and expressed his desire to make it more memorable by utilising most of the opportunity.
Sagor meanwhile is the only member in Bangladesh contingent for Rio who has experience at this level having participated in the 2012 Olympics in London. The country's fastest swimmer clocked 24.68s to place 39th among 58 swimmers four years ago.
He spent a one-year scholarship provided by FINA in Thailand and returned home last month. Sagor admitted that the course improved his performance and he also made his best timing there in 2016 Thai Open clocking 23.93s.
