He spoke quite a bit about Jurek (although he kind of steered clear of the veganism) ... and he was linking compassion and competition, citing endurance athletes helping each other out. His compassion angle was speciesist because he didn't follow it through to compassion for animals but it was interesting none the less.
He talked a lot about barefoot running although it was interesting to note that there is only 1 barefoot runner in the book, and the he comes across a bit mad. He was at pains to point out that the book wasn't about barefoot and only became a kind of bible for that movement after it was written - he had not run barefoot until after it was published.
He showed a clip from an HBO sports news program where they actually got quotes from the shoe manufacturers about the apparent backlash against the lack of injury reduction from increasingly cumbersome shoes which was interesting... and he spoke a lot about running form - pointing out that minimal shoes or no shoes improve form and increase feedback from the feet, allowing reduction in injuries.
Very interesting and he seemed like a genuinely nice bloke hoping to spread the word about running form and reduced injuries. If anyone gets a chance .. go see him talk
