National sprinter Mario Burke believes he has what it takes to give a really good account of himself at the 2020 Tokyo Summer Olympics in Japan.       An ambassador for Red Bull and Nike, the 24-year-old Burke said he isn’t going to the Olympics just to say “I have attended”. Rather he intends to go all the way in the 100m final at his first-ever Olympic Games for Barbados.“From the time I started track and field, it has always been a goal of mine to represent Barbados at the Olympics. To finally be able to do it this year in these challenging times, I am extremely proud of myself and just ready to go out there and put my best foot forward. I don’t just want to go there to take part, I want to go there to compete in the Olympics
