Book Synopsis

A triathlon is no small feat--train with guidance from a certified coach.

Unlocking Triathlon is the ultimate tool every triathlete needs leading up to race day. Whether you have experience with one sport or all three, this guide aims to meet you where you are and build from there.

Maybe you have already completed your first triathlon but feel like you have more to learn, or maybe this will be your debut race; either way, the information provided within this book will supplement the experience you already have and fill in the gaps across swimming, biking, and running. Author Alison Freeman is a triathlete, writer, and USA Triathlon Level III Coach who specializes in guiding beginner and intermediate athletes through their first triathlon experiences.

This book equips you to train smarter, with skill and fitness development tailored to your goals, and prepares you for the details of race weekend: fueling, transitions, packing lists, and more. Use the highly structured training plans for sprint-, Olympic-, and half-distances to build the ideal season, with customization options to focus on areas in which you will need extra support.

With essential training and skill techniques for swimming, cycling, and running, alongside race preparation, gear selection, plan adjustments, and training strategies, Unlocking Triathlon is your go-to guide for all things triathlon.
