Brothers Tobias Petersson and Bobbo Petersson run Gothenburg Lap in honor of their brother. Fredrik "Fredde" Petersson died from cancer last year.

The brothers have started a fundraiser to raise money for the Swedish Cancer Society. At the time of writing, the collection is close to SEK 70,000. The goal was to raise SEK 10,000, but so far the goal has been surpassed by more than SEK 20,000 and the brothers have raised over SEK 50,000 in total.
