As we reported nearly three weeks ago, Cecil Lammey and Sigmund Bloom of Footballguys.com will be hosting a 12-hour megashow on BlogTalkRadio’s The Fantasy Sports Channel on Saturday (Aug. 29) to raise money and awareness for cystic fibrosis research.

The Audible’s Drive for Cystic Fibrosis will kick off at noon Eastern on the FSC and run all the way to midnight (for the non-math majors in our audience), with Footballguys.com’s Matt Waldman and Andrew Garda of ThunderingBlurb.com stepping in for 30-minute breaks at 3 p.m., 6:30 p.m. and 10 p.m.

The hosts will be talking football and fantasy football all day with a slew of guests (including me at 4 p.m.). Bloom says the “tentative” schedule of topics looks like this …

12:00-1:30 — Quarterbacks
1:30-4:30 — Running Backs
4:30-7:30 — Wide Receivers
7:30-9:00 — Tight Ends/Kickers/Defenses
9:00-12:00 — Free for all

A donation site has been set up in conjunction with the Cystic Fibrosis Foundation.

If you were to start with ESPN’s NFL Countdown on Sunday and watch to the end of the final game, you’d probably hit about 12 hours of football in a day. Now imagine talking fantasy throughout that span.

The Audible’s Cecil Lammey and Sigmund Bloom will hit the air on BlogTalkRadio’s The Fantasy Sports Channel on Aug. 29 for just that length of time to raise money and awareness for cystic fibrosis.

The Footballguys.com duo will hit the air at noon Eastern that Saturday and go straight through until midnight with just 30-minute breaks every three hours. (For each of those intermissions, Andrew Garda of The Thundering Blurb will step in.)

The event is designed to draw attention to the Cystic Fibrosis Foundation, and listeners will be able to make donations throughout the broadcast.

“We hope to raise awareness for CF, and we hope to raise quite a bit of money for this great charity,” Lammey told FSB.com. “There isn’t a better time of year than now to bring the fantasy football community together to support something as serious as Cystic Fibrosis.”

The Audible is among the most popular shows on The Fantasy Sports Channel and ranks among the top 90 audio podcasts on iTunes. In addition to fantasy talk from Lammey and Bloom, Lammey says the broadcast will include guest appearances by former Broncos guard and current ESPN analyst Mark Schlereth, ESPN.com NFL reporter Adam Schefter, Yahoo! Sports’ Jason Cole and Scout.com’s Adam Caplan, as well as other Footballguys.com staffers and some others.

The FSC put on a similar event to benefit the Cystic Fibrosis Foundation back on March 7, with Paul Greco and Lenny Melnick of FantasyPros911.com leading a 24-hour baseball-themed show.

FSB.com will pass along more info on the event, including the URL for donations, as it becomes available.
