Charitable organizations that developed partnerships with last October's 
27th Marine Corps Marathon raised more than $5.5 million for their causes.
The Marine Corps Marathon allots blocks of guaranteed entries to
partner charitable organizations to aid in fundraising efforts.  Runners may
enter an online lottery registration for a chance to gain entry to the race 
or run for a participating charity with a guaranteed slot. Partner causes 
ranged from AIDS research to helping the homeless.
