What is Old Bill's Fun Run?

One of the most inno­v­a­tive fundrais­ers in the nation, Old Bil­l’s Fun Run is also one of the most successful. 

This run has no fin­ish line. There are no podi­ums or medal cer­e­monies. It ends as it start­ed, togeth­er, unit­ed in a greater pur­pose. Here, every step, every pace, every indi­vid­ual spin of the wheel rep­re­sents a col­lec­tive spir­it — a shared vision of a more vibrant and enriched com­mu­ni­ty for all. Old Bill’s Fun Run exem­pli­fies the very best of Jack­son Hole. In this marathon of gen­eros­i­ty lies the oppor­tu­ni­ty for mean­ing­ful con­tri­bu­tion, for altru­ism ampli­fied by the kind­ness of oth­ers, and for the sin­gu­lar dri­ve to make a difference.

Since its incep­tion, Old Bill’s has brought an astound­ing $256 mil­lion phil­an­thropic dol­lars to our com­mu­ni­ty. These funds are busy feed­ing the hun­gry, sup­port­ing the sick and elder­ly, teach­ing kids to read, pro­tect­ing wildlife, build­ing afford­able hous­ing, enrich­ing our lives through the arts, and touch­ing the lives of every­one in Teton Coun­ty. Old Bill’s is admin­is­tered by the Com­mu­ni­ty Foun­da­tion of Jack­son Hole.
