BMX cyclists might have the fastest first two seconds of any event in the Olympic Games - coming out of a gate on an eight-meter high wall and going from zero to 35 miles per hour in just two beats. For American racer and two-time Olympian Connor Fields, those two seconds account for 75 percent of his training and often determine if he can win the race which often lasts less than 40 seconds. "We work our butts off and I think we have one of the most difficult sports in the Games because we require so many different skills," said Fields. At the London Olympics in 2012, Fields was the No. 1 seed in the final at just 19 years of age, the youngest racer in the field. He crashed, finished seventh and as he describes it "at 19 it is hard not to seem like the end of the world." Now 23, he has more balance in his life and keeps things in perspective.

Eddie Keogh: "'So who wants to photograph all the medallists?Õ Silence. It was the final meeting of the Reuters photo team that would cover all the Athletics at the Olympic Stadium. I was in a room of world class photographers and the medals had my name written all over it. Funnily enough doing the medals produced one of the most iconic pictures of the London Olympics when Usain Bolt met Mo Farah after receiving his Gold medal for winning the 5000m. Usain suggested they swap poses. It was a lovely moment, a historic picture and I was a very happy man when I saw the pictures on the screen of my camera."

Micronesia's Manuel Minginfel drops weights on the men's 62kg Group B weightlifting competition at the London 2012 Olympic Games in Britain July 30, 2012. Dominic Ebenbichler: "I shot the picture with a robot remote camera which was fixed on the roof and that I triggered from the ground. The difficult part is to set it up prior to each weight lifting event. You have to preset the focus and shutter speed and as the athletes are not all the same size, a little bit of luck is involved as to whether the picture will be sharp. In this case everything came together perfectly: Minginfel dropped his weights and gestured upwards, we had set the focus on just the right position and what a result!"

All the photographers were excited because we knew he was going to react in a very dramatic way so it was a lovely sequence of photos as he crossed the finish line - he put his hands over his head, he wrapped himself in the British flag, it was a very long celebration sequence, which is all you can really wish for as a photographer."

Louis Smith of Great Britain cries during the men's gymnastics qualification in the North Greenwich Arena during the London 2012 Olympic Games in Britain July 28, 2012. Dylan Martinez: "During the long build up to the London Olympics all eyes were on a few of the gold medal hopes - I remember the pressure on them growing as we got closer to the opening ceremony. The British gymnastics team had a few high profile members but none more so than pummel star Louis Smith. I had photographed him at past championships and was always impressed by his focus. So with music blaring and a sell out crowd cheering, Louis steps up and absolutely nails his routine - as he came off the pummel it was as if pressure of the last few years suddenly lifted from his shoulders and he could finally breath again. He sat down and somehow oblivious to all around himÊ a couple of tears roll down his cheek and luckily for me he was sitting in front of some rings... But the best thing about this photograph is Louis Smith told me it was his favourite picture of the whole Olympics. Both him and his mother have a large print on their living room to walls."

Kai Pfaffenbach: "It was difficult to shoot the picture as Harting played cat and mouse with the few in-field photographers who were allowed to follow him on his honour lap. He did the shirt thing twice before at world championships so none of the photographers wanted to miss the opportunity. I was lucky for a moment before another photographer, who came in too late, ruined everybody else's pictures." REUTERS/Kai Pfaffenbach SEARCH "OLYMPIC HISTORY" FOR THIS STORY.

Palestinian swimmer Mary al-Atrash can't wait to make a splash at the Rio Olympics in August, but participation, rather than a podium finish, is probably the best she can hope for. Atrash competes in the 50 metres freestyle but her best time of 29.91 seconds is more than four seconds slower than the Olympic qualifying threshold of 25.28 seconds, in itself almost two seconds behind the world record. Atrash will be one of six Palestinians competing in Rio and the delegation will be the largest Palestine has sent to the Games since its first participation in the Olympics in Atlanta in 1996. Five competitors appeared in London in 2012. "I am so happy, representing Palestine in competitions is a dream for any Palestinian athlete, especially the Olympics," Atrash told Reuters. The 22-year-old university graduate's preparations have been hampered because she does not have an Olympic-sized pool to train in. There are none in the Palestinian territories and she has to settle for a 25-metre pool. REUTERS/Ammar Awad SEARCH "Al-ATRASH AWAD" FOR THIS STORY. SEARCH "THE WIDER IMAGE" FOR ALL STORIES.
