Question: In what country was Alyson Dixon unable to finish a marathon due to a calf injury?
Context: Andries Pretorius (born 26 September 1985) is a former Wales international rugby union player who played for Cardiff Blues in the Pro12 league and Worcester Warriors in the RFU Championship.  He played at Number 8, but also played at Blindside Flanker and in the Second Row.  He left Cardiff Blues to sign for Worcester Warriors in the RFU Championship from the 2014-15 season.  He never made his competitive debut for Worcester due to suffering a calf injury in pre-season.  On 30 January 2015 it was announced he was to retire from rugby with immediate effect on medical grounds. Adriana Nelson, née Pirtea (born January 31, 1980) is a Romanian American long-distance runner who made her marathon debut in the Chicago Marathon held on October 7, 2007, with a second-place finish.  She led by a few dozen meters in the final 300 meter stretch run down Columbus Drive on a day of record-setting 88 °F temperatures, but she was caught just before the tape by the defending Chicago Marathon women's champion, Berhane Adere.  Pirtea had held a 30-second lead with 600 meters remaining but never looked back as Adere slipped down the right side of the final straightaway under the shield of male runners.  Adere was so far to the right that as she crossed the finish line she did not take the tape which was being held at the left side of the finish line.  The 2007 Chicago Marathon was the slowest women's Chicago finish since 1992 due to the heat.  Pirtea had been a pacemaker at the January 28, 2007, running of the Osaka Ladies Marathon, and an injury prevented her from making her marathon debut at the London Marathon on April 22, 2007. Arthur Barry Magee MNZM (born 6 February 1934) is a retired New Zealand long-distance runner.  He won a bronze medal in the marathon at the 1960 Olympics and in the 10,000 m event placed 26th at the 1960 and 23rd at the 1964 games.  He withdrew from the 1964 Olympic marathon due to an injury. England competed at the 2014 Commonwealth Games in Glasgow, Scotland. Jesse Huta Galung and Stéphane Robert were the defending champions, but Robert chose not to participate this year.  Huta Galung was scheduled to play alongside Pablo Andújar in the qualifying draw, but withdrew with a right calf injury. Samiri (Qur'an 20:85, 20:87 and 20:95) is the name given in the Qur'an to the creator of the Golden Calf.  He was the man who tempted the Israelites to forsake the worship of Allah while Musa (Moses) was away for 40 days on Mount Sinai while he and the other Sahabah (companions) believed Musa (Moses) had died.  The Qur'an narrates that Samiri gave the illusion that the idol was making a 'lowing' sound, and the Qur'an further expands upon this, narrating that Samiri cast the dust which archangel Gabriel (Jibril) had tread upon onto the calf, while some prominent exegesists narrate the sound was made due to the wind entering and exiting the statue, and some posit the sound was due to the use of the dust.  In sharp contrast to account given in the Hebrew Bible, the Qur'an does not blame Aaron (Haroun) for the creation of the calf and instead praises him for trying to stop the worship of the calf. Alyson Dixon (born 24 September 1978 in sunderland) is an English long-distance-runner who has competed in several marathons and half marathons and won the 2011 Brighton Marathon.  She competed for England at the 2014 Commonwealth Games, but did not finish due to a calf injury.  She first joined an athletics club as a girl when a friend did and because she wanted to go to Flamingo Land Resort as the club was going there. Innocent Mdledle (born 11 December 1985 in Matatiele, Eastern Cape) is a South African professional footballer who plays at left-back for SuperSport United F.C. in the Premier Soccer League and for the South Africa national football team.  On 26 September 2007, Mdledle was added to the South Africa squad competing in the 2007 COSAFA Cup, even though he was just returning from a calf injury. A half marathon is a road running event of 21.0975 km (13 mi 192½ yd) – half the distance of a marathon.  Participation in half marathons has grown steadily since 2003, partly due to the fact that it is a challenging distance, but does not require the same level of training that a marathon does.  In 2008, "Running USA" reported that the half marathon is the fastest growing type of race.  A 2010 article by "Universal Sports" mentioned the growing popularity of the distance.  It is common for a half marathon event to be held concurrently with a marathon, using almost the same course with a late start, an early finish or shortcuts.  If finisher medals are awarded, the medal or ribbon may differ from those for the full marathon.  The half marathon is also known as a 21K, 21.1K or 13.1 miles, although these values are rounded and not formally correct. Gustaf Edvard Törnros (18 March 1887 – 2 April 1941) was a Swedish long-distance runner.  He competed in the marathon at the 1906, 1908 and 1912 Summer Olympics with the best result of fourth place in 1906.  Half of the participants, including Törnros, failed to finish the 1912 marathon due to the hot weather with temperatures exceeding 30 °C.  Törnros won the national marathon title in 1911 and 1912.
