Today, almost 40 years later, the Swedish Childhood Cancer Foundation is the largest financier of childhood cancer research in Sweden and today more than 85 percent of the affected children survive. Between September 11-20, thousands of runners will run the Run of Hope virtual edition, where RaceOne is the official app partner, where last year more than 1mSEK was collected. .
