  • "This is the perfect start to finish guide to getting ready for your first Ironman 70.3 race. The distance is the perfect blend of speed and endurance. And Brittany's book is ideal to get you ready for that challenge by providing you with what to do and what not to ensure you arrive at the start line fit and ready to go. The best part is she takes into account what for most is a busy life outside of triathlon and gives you tips to keep it all in balance. Well done Brittany! "

  • "Read this just before my first 70.3, and it was SO helpful! There’s a ton of useful information about setting up transition and preparing for the race, but the thing that helped me the most was how she talks about your mindset going into the race. My race was particularly difficult, because of bad weather, and there were quotes from this book that stuck with me- particularly this quote ‘We don’t train so the race isn’t hard. We train so we can persevere when the race gets hard.’”

  • "I really appreciate how you write, your voice, and your experience. I'm a person who has been circling triathlon training, fandom, and the lifestyle of a multi-sport athlete for years. In 2026, I would like to accomplish some very real behavior changes, and I believe Brittany's newsletter to be a fantastic resource to me, as a curious student athlete."
