Cloudbase Mayhem
A podcast by Gavin McClurg (X-Alps contestant, US foot launch distance record holder, NatGeo adventurer of the year, etc.), definitely one of my favourites. Our sport's greats are interviewed here. Lots and lots to learn from these podcasts. Also check out the rest of his website for mucho cool stuff.

To find their podcasts go through their blog archive. A lot of informative interviews on how to become better and safer pilots.
