Last month, Broncos quarterback Peyton Manning gave $500,000 to the Pat Summitt Foundation for the fight against Alzheimer’s Disease.

Today, Manning’s PeyBack Foundation is donating $581,000 that will be distributed to more than 90 youth-based community organizations in Colorado, Indiana, Tennessee and Louisiana for 2013.

Add it up and Manning has donated more than $1.081 million in the past two months.

“The mission and work of the PeyBack Foundation is something we are very passionate about,” Manning said in a statement. “We are pleased to add Colorado to our giving cycle and are proud of the positive impact that so many youth-based organizations in this state, as well as in Indiana, Tennessee and Louisiana, have on our communities.”

In Colorado, 37 youth-related charities will receive a total of $288,750 in grants. Twelve organizations in Indiana will receive $52,500 while 15 Louisiana organizations will receive $78,750 and 25 Tennessee organizations will receive $161,000.

The PeyBack Foundation, a public non-profit corporation, was established by Manning in 1999 to promote the future success of disadvantaged youth by assisting programs that provide leadership growth and opportunities for children at risk. The PeyBack Foundation has donated more than $6.5 million through its grants and programs since its inception.
