Boston Marathon runners participating on behalf of the Dana-Farber Cancer Institute since 1990 have surpassed the $100 million fundraising mark.
The research center says more than $500,000 has already been raised by runners in next year's race, putting it over the threshold.
Dana-Farber was one of the first charities allowed to use the Boston Marathon as a fundraiser.
More than 500 runners are expected to take part in the 2020 race as part of the Dana-Farber Marathon Challenge. They are hoping to raise $6.25 million.
One hundred percent of the money raised from the team's Boston Marathon runners supports promising cancer research in its earliest stages.
