    Tune Up Race Formula: Timing, Recovery, and What the Training Theory Says

    Tune-up races are a common piece of many training plans. Are they necessary? Why should you bother racing in the middle of training? In this episode, we discuss all you need to know about how to run an effective tune-up race (and whether to run one at all). We draw from years of coaching experience and an understanding of various training theories to guide you through how to incorporate non-goal races into your training, in a way that does not detract from your goal race. You will learn how to schedule them, whether you need to taper, and how to recover. Plus, we will provide guidance for what to do if doing tune-up races just is not for you. In this episode, you’ll learn: ✅ The psychological and physiological benefits of a tune-up race ✅ How to schedule tune-up races in your training ✅ Which distance tune-up race should you choose? ✅ Different pacing approaches for tune-up races ✅ If you should taper for a tune-up race ✅ How to recover after a goal race ✅ Benchmark workouts as substitutes for a tune-up race Tread Lightly Running is hosted and researched by Amanda Brooks and Laura Norris, MSc. Production, show notes, and graphics by Laura Norris.

    The Psychology Behind Peak Running Performance with Dr. Trent Claypool

    “Performance is your potential minus interference - and the brain often interferes with how well we want to do.” Many runners struggle to translate their training to racing, because of race day nerves, negative self-talk, or fear of discomfort. In this episode, we are joined by Dr. Trent Claypool of Summit Sport Psychology to learn how to embrace discomfort, use positive self-talk, and train your brain for your peak performance.
