World record-breaking endurance adventurer and IRONMAN coach Sean Conway has launched his latest book, ‘The Iron Distance Playbook – 140.6: Everything You Need to Complete Your 140.6 Triathlon’. The book aims to synthesise 15 years of endurance experience into a comprehensive guide for aspiring triathletes.
Best known for completing 105 full iron-distance triathlons in 105 consecutive days in 2023, the North Wales-based athlete designed the 420-page paperback to serve as an accessible self-coaching manual. The book covers the full 140.6-mile distance – 2.4-mile swim, 112-mile cycle, and 26.2-mile run – and includes a structured 50-week training plan alongside swimming, cycling, running, strength, and conditioning protocols.
At the core of the playbook is Conway’s 10.5-pillar approach to endurance preparation, covering nutrition, hydration, pacing, equipment selection, and race-day strategy, supported by digital checklists and video tutorials.
Sean Conway said “I’ve put my whole coaching knowledge and my 15 years of experience into one book with everything you need to know, a training plan that works. Ironman can be expensive, right? So I wanted to give people an affordable option to basically self-coach themselves. It’s been so rewarding putting this together. I wanted to put all that knowledge, specifically around Ironman and iron-distance events, into a book.”
He added “Firstly, I always say to people, just go and start enjoying the thing that you’ve signed up for. I think we can all get too bogged down by the numbers and you suddenly get the watch and everything, and look, all that stuff’s great. But then it can sort of ruin the fun of it, right? Just go out and just start running.
“Don’t look at other people’s data. Don’t compare yourself to anyone else. You’re on your own little adventure. I think people expect the results too soon and then they get deflated. But it takes a while, everyone, endurance takes a while. So just stick at it, chip away at that block, and then suddenly you’ll realise you’ll be flying.”
Conway’s career achievements also include cycling around the world, swimming the length of Britain, completing a 4,000-mile ultra-triathlon, and breaking the record for cycling across Europe. After competing at IRONMAN Wales in 2026, he continues to coach and write for endurance athletes.
The Iron Distance Playbook – 140.6 was published on October 27, 2026, and is available via Amazon.
