I'll promote your blog, project, brand, whatever, in a 30 second on air spot on the podcast. (As long as it's all nice and awesome and not, y'know, inflammatory or negative). Along with the on air ad, you will also receive the Official Backer badge and will be listed on the podcast's official website as a Supporter.
Create a running, health, fitness, etc. related question that I'll ask all guests that appear on the podcast! You'll also receive the Official Backer badge and be listed on the website's supporter's page.
