A half marathon is a road running event of 21.0975 kilometres (13.1094 mi). It is half the distance of a marathon and usually run on roads. Participation in half marathons has grown steadily recently. One of the main reasons for this is that it is a challenging distance, but does not require the same level of training that a marathon requires. In 2008, Running USA reported that the half marathon is the fastest growing type of race. A 2010 article by Universal Sports echoed the growing popularity of the distance.New York Road Runners CEO Mary Wittenberg and noted running author and coach Jeff Galloway have also commented on the 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. The half marathon is also known as a 21K, 21.1K or 13.1 miles, although these values are rounded and not formally correct.

Most people tend to run a half marathon before running a full marathon. A half marathon will help to prepare the body and the mind for the 42.195 kilometres (26.219 mi) that makes up a marathon. Running a half marathon is both physically and mentally demanding. For those who have never run this distance before, it is imperative to train correctly. It is advised to slowly build up endurance over a twelve weeks period; decreasing the intensity of the training in the last week, or Tapering, before the event. If the body is over-worked, injury is more likely to occur. It is also important to eat correctly and stay hydrated before, during, and after the race.

Sonata Arctica is a Finnish power metal band from the town of Kemi, originally assembled in 1995. Their later works (most notably The Days of Grays, Unia and a few tracks on Reckoning Night and Winterheart's Guild) contain several elements typical of progressive metal.

The band was founded by Marko Paasikoski, Jani Liimatainen and Tommy Portimo in Kemi at the end of 1995 (Tony Kakko and Pentti Peura joined in early 1996). Originally named Tricky Beans, they played hard rock rather than the power metal with which they grew to fame. During their early career, they recorded three demos which were never sent to any recording label — Friend 'till the End, Agre Pamppers and PeaceMaker.

In 1997 the band changed their name to Tricky Means, and from that point until 1999 their style was thoroughly worked upon and ultimately was drastically changed, acquiring strong emphasis on the keyboard melodies and relying on an easily distinguishable rhythm line maintained both by the bass and the guitar. Vocalist Tony Kakko developed a clean singing style which relies both on falsetto and tenor voices and second guitarist Marko Paasikoski left the band. Kakko has stated that the change of sound was influenced by fellow Finnish power metal band Stratovarius.
