In the spring of 2015, Mark Beaumont set out from the bustling heart of Cairo on his latest world record attempt - solo, the length of Africa, intending to ride to Cape Town in under 50 days. Seven years since he smashed the world record for cycling round the world, this would be his toughest trip yet. And he would set a new mark that would simply break the limits of endurance.

Despite illness, mechanical faults, attempted robbery and stone-throwing children, as well as dehydration in the deserts and unprecedented levels of exhaustion, Mark completed the journey in just 41 days, 10 hours and 22 minutes, after cycling 6,762 miles, spending 439 hours in the saddle (sometimes up to 16 hours a day) and climbing 190,355 feet through 8 countries. It was an astonishing journey, and one that will fascinate and grip the reader.

From the obvious dangers of Egypt, Sudan and Kenya, over the unpaved, muddy, mountainous roads of Ethiopia, through the beautiful grasslands of Tanzania and Zambia, to riding at night in Botswana in the company of elephants and giraffes, Mark brings Africa to life in all its complex glory, friendship and curiosity, while inspiring us all to question the bounds of what is possible.

As the world becomes increasingly complex, so do the statistical models required to analyse the challenging problems ahead. For the very first time in a single volume, the Handbook of Approximate Bayesian Computation (ABC) presents an extensive overview of the theory, practice and application of ABC methods. These simple, but powerful statistical techniques, take Bayesian statistics beyond the need to specify overly simplified models, to the setting where the model is defined only as a process that generates data. This process can be arbitrarily complex, to the point where standard Bayesian techniques based on working with tractable likelihood functions would not be viable. ABC methods finesse the problem of model complexity within the Bayesian framework by exploiting modern computational power, thereby permitting approximate Bayesian analyses of models that would otherwise be impossible to implement. The Handbook of ABC provides illuminating insight into the world of Bayesian modelling for intractable models for both experts and newcomers alike. It is an essential reference book for anyone interested in learning about and implementing ABC techniques to analyse complex models in the modern world.

The inspiring story of one young man's record-breaking solo cycle journey around the world On 15 February 2008, Mark Beaumont pedalled through the Arc de Triomphe in Paris. 194 days and 17 hours previously, he had begun his attempt to circumnavigate the world in record time. Mark smashed the Guinness World Record by an astonishing 81 days. He had travelled more than 18,000 miles on his own through some of the harshest conditions one man and his bicycle can endure, camping wild at night and suffering from constant ailments. The Man Who Cycled the World is the story not just of that amazing achievement, but of the events that turned Mark Beaumont into the man he is today. From the early years of his free-spirited childhood in the Scottish countryside to present day, he has been equally determined not to settle for an average existence, but to break free and follow his dreams. Mark Beaumont grew up in the foothills of the Scottish Highlands. When he was twelve, he cycled across Scotland, then a few years later, completed the 1,000 mile solo ride across Britain from John O'Groats to Land's End. His next long-distance ride took him the length of Italy, a journey of 1,336 miles, helping to raise GBP50,000 for charity. After graduating from Glasgow University, and having also qualified as a professional ski instructor, he decided against a conventional career and devoted himself full-time to raising money for his endurance adventures.

The inspiring story of one man's record-breaking cycle around the world. On Monday 18th September 2017, Mark Beaumont pedalled through the Arc de Triomphe in Paris. 78 days, 14 hours and 40 minutes earlier he set off from the same point, beginning his attempt to circumnavigate the world in record time. Covering more than 18,000 miles and cycling through some of the harshest conditions one man and his bicycle can endure, Mark made history. He smashed two Guinness World Records and beat the previous record by an astonishing 45 days. Around the World in 80 Days is the story of Mark's amazing achievement - one which redefines the limits of human endurance. It is also an insight into the mind of an elite athlete and the physical limits of the human body, as well as a kaleidoscopic tour of the world from a very unique perspective; inspired by Jules Verne's classic adventure novel, Mark begins his journey in Paris and cycles through Europe, Russia, Mongolia and China. He then crosses Australia, rides up through New Zealand and across North America before the final 'sprint finish' thorough Portugal, Spain and France, all at over 200 miles a day. This is the story of a quite remarkable adventure, by a quite remarkable man.

In 2008, Mark Beaumont smashed the world record for cycling around the world, by an astonishing 81 days. His race against the clock took him through the toughest terrain and the most demanding of conditions. In 2009, Mark set out on his second ultra-endurance challenge. And this one would involve some very big mountains. The Man Who Cycled the Americas tells the story of a 15,000 mile expedition that once again broke the barriers of human achievement. To pedal the longest mountain range on the planet, solo and unsupported, presented its own unique difficulties. But no man had ever previously summited the continents' two highest peaks, Mt McKinley in Alaska and Aconcagua in Argentina, in the same climbing season, let alone cycling between them. Oh, and Mark had never even been up Ben Nevis before. Full of his trademark charm, warmth and fascination with seeing the world at the pace of a bicycle, Mark Beaumont's second book is a testament to his love of adventure, his joy of taking on tough mental and physical feats, and offers a thrilling trip through the diverse cultures of the Americas.
