Intense Running

On the outside, he is a quiet calm of a man.  Watching him sitting and contemplating the madness surrounding him, you sense a deep serenity.  Inside, however, the fires burn with hot intensity.  Sometimes they burst out to the surface – a head twitch here, a leg shake there – but it’s never more apparent then when you look in his eyes. At first glance, you see a deep peacefulness.  At closer inspection, you see a fire burning bright, forged deep in his soul.  Everything is lighthearted; nothing is casual.  He considers the Barkley Marathon.  What would Francisco d’Anconia do?
