Runs in the memory of her little sister Katrín Una Sigurðardóttir with her little sister, Elvíra María, in her arms. Photo/Sent to mbl.is Katrín Una Sigurðardóttir, a nine-year-old girl from Siglufjörður, plans to take part in the Reykjavík marathon today.

She runs in the recreational race in memory of her sister, Elvíra María, who died last year after a battle with acute leukemia. In an interview with mbl.is, Katrín's mother, Sigrún Sigmundsdóttir, says that Katrín is an open, playful, and creative person and is very excited about the upcoming race.

She is also very enthusiastic about the fact that she has collected a lot of money, but Katrín herself decided to run for the Mía Magic charity. "She was completely determined as soon as she saw an advertisement for the Reykjavík Marathon to run for Mía Magic," Sigmundsdóttir says. A charity that reaches out to the children The charity focuses on making chronically ill children and their parents happy as well as publishing educational books.

Sigmundsdóttir says that a lot of support came from the association after her daughter Elvíra was diagnosed with acute leukemia, but one of the things Mía Magic does so well is to connect with the children. Both Elvíra and Katrín got the so-called Míubox from the company, but each Míubox is tailored to each person who receives it and contains various items, and Elvíra got a Míu teddy bear that she hardly let go of.
