Dear [Name],
Thank you! Thank you for supporting my journey. Thank you for supporting Susan G. Komen®. Thank you for your donation - your gift will help save lives. You can read more about the Susan G. Komen 3-Day® and the efforts your donation goes to support at The3Day.org.
So far I've raised [$amount] - only [$amount] more until I reach my goal! My training is on track, too. So far I've logged [#] miles. It's not easy, but with the support of friends like you, I know I'll succeed.
I'll be keeping all of my donors in mind, and in my heart, as I walk 60 miles for the Komen 3-Day. Without your generosity, none of this would be possible.
Sincerely,
[Name]
