Två Sjöar Runt is a long-standing spring running event held in Sundbyberg and Solna, Stockholm. The course circles the lakes Lötsjön and Råstasjön, featuring both flat sections and a notable climb at Spelmanshöjden. The event includes races for children, youth, and adults, attracting elite, recreational, and young runners. All races start and finish at Sundbybergs IP, where spectators gather to support participants. Every finisher receives a traditional plaque, and prizes are awarded to top finishers and through random draws. The event is a recognised tradition in the Stockholm running community.
