'A wonderful read...I highly recommend it' - Adharanand Finn, author of Running with the Kenyans. When Michael Stocks stands at the starting line of a 24-hour race on an athletics track in South London, it is noon and rain is beginning to fall. His aim is to run more than 150 miles by noon the following day, in order to fulfil his dream of being selected to run for Great Britain. He is 49 years old, and it will require the performance of a lifetime. One Track Mind tells the story of these 24 life-changing hours. It reveals the mental tools that make it possible to run six marathons in a single day, and how they can be applied to other parts of life. And it shares the realisations about life that remain long after the race has ended. A love letter to a race, to a community at the frontier of sport and to life itself, One Track Mind is an inspirational examination of the fascinating world of extreme endurance.

"My work as a scientist who studies bird parasites causes me to wonder about the hidden part of the drama unfolding before my eyes: the flying zoo that makes each bird what it is. As I gaze out at my favourite birds, I wonder what role their parasites have played in shaping their fascinating behaviours and alluring appearance." - From Chapter 1 In The Flying Zoo, Michael Stock gives readers an enthusiastic tribute to birds and the parasites that live in and on them. From the Crozet Archipelago and the Galapagos Islands to our own backyards, parasites-fleas, lice, ticks, and flukes-live in a sinister yet symbiotic relationship with their host birds. With a scientist's exuberance, Stock reveals a co-evolutionary dance among an astounding cast of creatures living in a complex and paradoxical co-habitation. Following in the footsteps of Fleas, Flukes and Cuckoos, this contemporary classic deserves a place on the shelves of students and teachers of biology, natural history buffs, and birders.
