Day ten of the Olympic Games, and day one inside Tokyo's Izu Velodrome for a week of track cycling drama. Traditionally an area dominated by Team GB, they are expected to face stiff competition this time from strengthening opposition. Early on, Jasmine Camacho-Quinn swept to victory in the 100m hurdles, claiming a first ever track and field gold for Puerto Rico. The 24-year-old - who had set an Olympic record 12.26sec in the semi-finals - surged home to claim her first major title in 12.37sec. "Waking up this morning, there was adrenaline just rushing. I was like, 'let's get it.' I was working on six hours of sleep - I didn't care, I had a goal. I definitely came here and accomplished that," she said afterwards. "It's amazing. The first gold medal in track and field for Puerto Rico and the second gold medal ever - I don't know how to explain it right now but it really does mean a lot." There was drama in the men's long jump as Miltiadis Tentoglou won with his last leap of 8.41 metres which tied with Cuba's Juan Miguel Echevarria's jump, but the Greek secured the title on a countback with his next-best effort of 8.15m ahead of the Cuban's 8.09. We will keep you updated with all the gold medal winners as they happen in the photo gallery above. <br/> <br/>
