Free Ultrarunning Training Assessment! Endurance athletes have access to more performance information than ever before, but that hasn't necessarily made it easier to separate good science from a convincing sales pitch. In this video, CTS Director of Coaching Cliff Pittman breaks down what evidence-based training actually means and why it isn't as simple as finding a study that supports your argument. Cliff examines how pseudoscience gains credibility, why elite athletes aren't proof that ...

“Never increase your weekly mileage by more than 10%.” It’s one of running’s most repeated rules, but the evidence doesn't support using 10% as a simple weekly-volume ceiling. A randomized trial found no reduction in injuries from a gradual program based on the 10% rule, and newer research following more than 5,000 runners found no relationship between week-to-week percentage changes and injury rates. Cliff Pittman breaks down where the 10% number does show up in the research, why different s...

Should a low HRV reading change your workout? Is higher HRV always better? And should you trust the readiness score on your watch? CTS Director of Coaching Cliff Pittman breaks down what HRV actually measures and, more importantly, how endurance athletes should use it. He explains why your individual baseline matters more than the absolute number, why HRV can naturally decline during productive training, and when a sustained change actually deserves your attention. HOST Cliff Pittman is the...

There are hundreds of things you could optimize before your first 50K. Very few of them will determine whether you have a successful race. CTS Director of Coaching Cliff Pittman breaks 50K preparation into three tiers: the basics that can make or break race day, the refinements worth getting right, and the marginal gains you can probably stop stressing about. From training volume and event specificity to recovery, nutrition, strength training, gear, supplements, and race-day pacing, this epis...

Downhill running creates a strange mismatch: it can feel relatively easy aerobically while placing enormous mechanical stress on your legs. Coach Cliff Pittman explains what's happening inside the muscle during a descent, why technical terrain increases the cost, and how the repeated bout effect allows your body to become more resistant to downhill-induced damage. He also covers how to train when you don't have mountains outside your door, where strength training fits, when to schedule race-s...

There are two fears Cliff Pittman sees repeatedly: athletes hold onto speed work because they don't feel fit without it, or they avoid increasing volume because they're afraid more running will eventually break them down. In this episode, Cliff explains why both miss the point. He breaks down what aerobic volume actually changes physiologically, why those adaptations take time, how intensity should shift as race day approaches, and how training architecture allows athletes to increase volume ...

Elite athletes don't just pick a carbohydrate target and hope for the best. Their fueling strategies are built, tested, practiced, and adjusted around three key levers: carbohydrates, fluid, and sodium. Precision Fuel & Hydration Sports Scientist Emily Arrell joins Cliff Pittman to explain how those plans come together—from sweat testing and gut training to making real-time decisions when things go wrong on race day. HOST Cliff Pittman is the Coaching Development Director at CTS, leadin...

Racing at altitude can feel intimidating, especially if you live at sea level. Should you buy an altitude tent? Sleep in a hypoxic chamber? Wear an altitude mask? In this episode, CTS Director of Coaching Cliff Pittman explains what actually improves altitude performance, how to time your arrival before race day, where heat training fits, and why your biggest advantage is still the fitness you build before you travel. Whether you're preparing for Leadville, Pikes Peak, or any race at elevatio...

HOST Cliff Pittman is the Coaching Development Director at CTS, leading the Ultrarunning and Cycling Coaching staff with a specialty in guiding athletes from first-time ultrarunners to elite...

Heart rate or pace? For years, runners have debated which is better, but both measure different parts of the same effort. In this episode, CTS Director of Coaching Cliff Pittman explains why RPE is the missing piece, how perceived effort integrates cardiovascular strain, metabolic demand, and mechanical loading, and why learning to trust it can improve both training and race-day pacing. HOST Cliff Pittman is the Coaching Development Director at CTS, leading the Ultrarunning and Cycling Coac...
