Teton Valley’s fifth annual Tin Cup Challenge is kicking off at the end of this week. The Community Foundation of Teton Valley begins accepting donations to participating nonprofits Friday leading up to the fun run in July. This year, the Community Foundation of Teton Valley has set out to increase overall giving by 15% over last year with a goal of raising $5-million in five years. Last year, the Tin Cup Challenge raised over $1-million for local organizations. Donations typically are matched in the range of 50% thanks to community challengers who donate to the match fund. Information about donations and participating organizations are being mailed out to Teton Valley Residents this weekend.
