Zara Phillips Makes Her Olympic Debut 
 
 London may still be buzzing about the Queen's spectacular cameo at the Olympics Opening Ceremony on Friday, but Her Majesty's granddaughter has clearly moved on.Asked about her grandmother's dramatic entrance, Phillips told reporters with a smile, "I'm not going to answer that. This is sport!"Indeed, Sunday marked the 31-year-old's Olympic debut , competing in the Dressage portion of the equestrian three-day eventing competition. And Phillips was clearly delighted to be getting down to work.The royal beamed as she entered the arena on her horse, High Kingdom, to cheering home crowds. Among the spectators: her husband of nearly one year, Mike Tindall , who watched from the sidelines and planted a huge kiss on her lips as she dismounted in the paddock.Prince Phillip, Princess Anne, Zara's brother Peter and his wife Autumn all watched expectantly from the stands as well. Phillips, a former European and World champion, declared herself "really pleased," despite a couple of mistakes, and said that entering the arena had been "incredible.""It's an amazing feeling to be part of the Olympics and to ride for your country and just to be there," she said. "The crowds are amazing as well." Luckily for Phillips and High Kingdom, the sun came out for their go – later, the competitors were drenched by rain.She'll be back in the saddle Monday afternoon for the Cross Country event, which will be far more dramatic that Sunday's controlled dressage performances (in Cross Country, competitors tackle a course of massive jumps dotted around a three-and-a half mile course).And Phillips's cousin, Prince William , and his wife Kate will be there to cheer her on. ||||| Paula Radcliffe out of Olympics marathon with injury 
 
 Paula Radcliffe will not compete in the marathon at the London 2012 Olympics because of a foot injury. 
 
 The 38-year-old, who has never won an Olympic medal in four previous Games, was declared unfit after a test run this weekend. 
 
 Radcliffe said the thought of competing at London had kept her "fighting, motivated and focused". 
 
 In a statement, she added: "That is why it hurts so much to finally admit to myself that it isn't going to happen." 
 
 Paula Radcliffe analysis "Paula will be absolutely heartbroken. It is unlikely she would have challenged for a medal, although she would have believed she could, but to have run in London and to have finished with her head held high after all the heartache she has had in previous Olympic marathons would have been very important to her." 
 
 Radcliffe, who is still the women's marathon world record holder and a former world champion, has suffered with osteoarthritis in her foot during her career. 
 
 Radcliffe added: "However hard today is, finally closing the door on that [Olympic] dream, at least I can know that I truly have tried absolutely everything. 
 
 "Now however, is the time to accept that it is just not going to settle in time. As desperate as I was to be part of the amazing experience of the London Olympics, I don't want to be there below my best." 
 
 UK Athletics and the British Olympic Association said they will nominate Scotland's Freya Murray as the replacement for Radcliffe, to be approved under the Late Athlete Replacement policy. 
 
 She will join Great Britain's other participants, Claire Hallissey and Mara Yamauchi, in the race on Sunday, 5 August. 
 
 Analysis Radcliffe, the greatest female distance runner this country has ever produced, desperately wanted to experience the unique opportunity of running an Olympic marathon in front of her home crowd 
 
 UK Athletics head coach Charles van Commenee said: "This is obviously a disappointing day for Paula and our sport but it was important to her that if she made the start line it would be in the best possible shape. 
 
 "It wasn't meant to be and she has taken the right decision to withdraw at this stage. 
 
 "I think it is important that we don't look at Paula's career in Olympic cycles. She is undoubtedly one of the greatest female distance runners of all times and still holds the marathon world record. 
 
 "When we look back at her career it should be in the context of what she has achieved and not what she hasn't. I wish her all the very best for her recovery."

 Radcliffe has been dogged by doubts about her fitness in the build-up to London 2012, leading to a trip to Germany for specialist treatment earlier in July. 
 
 She was rated 50-50 by Van Commenee as recently as last week. 
 
 Radcliffe has missed out on a medal in four Olympic Games appearances between 1996 and 2008, with her best performance coming on the track at the Sydney Games in 2000, when she was fourth in the 10,000m. 
 
 She won the marathon in the 2005 world championships in Helsinki and has won the London and New York marathons three times each.

 Kimberly Rhode won the gold medal in women's skeet shooting Sunday, making her the first American to take an individual-sport medal in five consecutive Olympics. 
 
 Rhode tied the world record and set an Olympic record with 99 points. Wei Ning of China took silver with 91 points and Danka Bartekova of Slovakia got bronze by beating Marina Belikova of Russia in a shootout after they tied with 90 points. 
 
 Rhode won a gold medal in double trap at Atlanta as a teenager in 1996, took bronze in that event four years later at Sydney, re-claimed the gold at Athens in 2004 and won the silver in skeet at Beijing in 2008. 
 
 In qualifying, Rhode set another Olympic record, missing only one of her 75 shots. Rhode led by four points entering the final, and the way she was connecting Sunday, there was no way she was getting caught. 
 
 USA Shooting touted it as the biggest day in shooting history. 
 
 Hard to argue with that. 
 
 Rhode was a perfect 25-for-25 in each of the first two qualifying sessions, then ran her streak to 65 straight hits before her lone qualifying misfire. Several people watching on a chilly, rainy day at the Royal Artillery Barracks sighed in disbelief at the miss, which Rhode shrugged off with ease. 
 
 When qualifying was complete, she flipped the last of the empty shells from her gun, gave a brief fist-pump, followed by a wave and a smile. Rhode thanked several well-wishers as she walked away, moments before rain started falling significantly harder. 
 
 The field started with 17 women from 17 nations, before getting pared to six for the final later Sunday.
