Why we Run by Bernd Heimrich

Just finished reading a fascinating book "Why we Run" by Bernd Heimrich. Biologist, award-winning nature writer and ultramarathoner Bernd Heimrich explores the anthropological, biological and psychological side of ultraendurance and dovetails the narrative with his own running efforts including running and winning an ultra-marathon 100 kms event - lots of insights into the sport of long distance running. Must read for all long distance runners.
