While out on my Sunday morning run this morning I listened to an interview that put my one-legged shufflings to shame.

The always-excellent To The Best Of Our Knowledge from Wisconsin Public Radio featured mountain climber and double AK amputee Warren MacDonald, who has written a book about his journey.

The programme also features a fascinating interview with Bill Siemering of Developing Radio Partners, a non-profit organisation which supports independent local radio stations in the developing world.

It's the best hour of radio you're likely to hear this year.
