It varies enormously by race. Boston's John Hancock charity program runs the highest bar, $7,500 to $15,000. Sydney's Grassrootz platform sets a flat AU$3,000 across every partner. New York's official partners range from $3,000 to $10,000. London's biggest partners cluster between £2,200 and £3,000. Berlin has two routes: five direct SCC EVENTS foundations from €500 to €1,195, and international Realbuzz partners from roughly $850 to $3,400.
Take the charity's published minimum, subtract anything you have already raised, and divide by the weeks left between today and that race's own race day from our majors data. It is simple division, not a projection: it tells you the flat weekly amount that clears the target exactly on schedule.
Deadlines vary by charity. Some, like Brigham and Women's Stepping Strong, publish staged milestones with partial payments due months out. Most simply require the full minimum by a single deadline close to race day, and several hold a credit card on file to charge any shortfall afterward.
Boston, by a wide margin. Its John Hancock Non-Profit Program partners mostly sit between $10,000 and $15,000, well above every other Major's charity route in this tool.
Berlin's direct SCC EVENTS foundations start around €500, and Chicago's Bank of America program starts at $1,500. Both undercut the $2,000-plus minimums typical at London, New York and Cape Town.
No, they are separate line items. Most charities charge a registration fee on top of the fundraising target, though not every partner publishes one. This tool shows the fee only where the charity has published it, and marks it as not published otherwise rather than guessing.
