If you’ve wondered how good Apple Watch really is for fitness, then you could do worse than try and train for an IronMan Triathlon using one. Ian covers all the three triathlon sports, swimming in indoor pools and open water, cycling on the road and training at home and running both on a treadmill and outside on the road or trail. Ian examines the standard Apple Workout app and recommends third party apps where the Apple one may fall short. He describes how to get your data into other platforms such as Strava and Training Peaks, and how to understand the Health app and the hidden data and depths it provides (such as Heart Rate Variability and VO2 Max) He covers closing your rings and sharing and competing with others using the Apple Activity app. Included in this book are 4 free Professionally designed training plans from 8 to 24 weeks for Sprint/Olympic/Half IronMan and Full IronMan triathlons, provided by coach John Rowland. Purchasing the book will also give you access to a private Slack group to discuss tips and tricks with other keen Apple Watch Triathletes. Developers welcome too, perhaps we can help build some world class health and fitness apps for Apple Watch. Covers Apple Watch Series 3 and 4 - Ian has used all Apple Watch versions, but it was with series 3 that he first began using it in anger for Triathlon Training. The new series 4 watch is covered in this book too.
