Inhalt: In 2015, Lawrence set his third Guinness World Record by completing fifty full-distance triathlons in fifty states in fifty consecutive days — a 2.4-mile swim, 112 miles on a bike, then a 26.2-mile run, all in under seventeen hours each day. Pushing himself further, in 2021 at the age of forty-five he set out to complete 100 triathlons in 100 days — a challenge so difficult that he wondered if he would survive it. By persevering, he hoped to inspire people to do the same for whatever difficulties they may be going through. Lawrence has subjected his body to exhaustive physical testing, to every genetic analysis known to science. The stunning discovery is that, physically, he is unspecial in every way. The secret to his bulletproof body is his bulletproof mentality. In this life-changing book he reveals how to: Say yes to opportunities. Develop confidence. Overcome obstacles holding you back. Forge an iron will by making and keeping small promises. Foster hope and resilience.
