We’ve said it before, and we’ll keep saying it: Thank you for sending us questions. We are here for you and your training. Nothing is more fulfilling than knowing that the hours of research, study, and production of the podcast is useful to you. In today’s Q&A episode, Coach Connor and I selected three questions to address. First, Peter Burghardt, thanks for asking us about intervals. We hope our dissection of the dreaded 4x8s is helpful! Enjoy Trevor’s graphs and analysis of his own rides. Next, David Sampier down in sunny, flat, Florida brought up a really good point: How do you adequately train for a big race, specifically Dirty Kanza, when you live in a geographical area that doesn’t offer the rugged, rolling terrain that you’ll be faced with on race-day? Finally, Jeremiah Bell, you know we love to talk about when to train in Zone 1, Zone 2 and so on, in the polarized model. Thanks for your specific question about cardiac drift and the causes of it. Let’s make you fast!
