You will also learn how to safely increase and support high volume training, so that you can secure the biggest driver: consistent training over years.

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).

Pronation can be misunderstood as a scary, dangerous risk for injury - and people use that to sell you something. In reality, a certain degree of pronation is a normal part of the running gait. However, excessive or limited pronation can be problematic for some runners. So how do you know if you need to worry about overpronation or buy stability shoes? In episode 171, we take an evidence-based approach and guide you through anatomy and recent research surrounding pronation.
