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.

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.

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.

 Törnros won the national marathon title in 1911 and 1912.
