Ironman Kona vs. Leadville 100. We ask athletes who have raced both and offer tips for success at each.

Heat, humidity, wind, pacing—we take a look at some of the factors that affect success at the Ironman World Championship in Kona.

Get the right mix of intensity at the right time and polarized training pays off. Take a disciplined approach for best results.

The concepts of central and peripheral conditioning help explain why an effective training base period leads to speed and durability in the race season.

Sticking to 80/20 and training by heart rate are just two of the key polarized training rules you’ll want to follow.

Polarized training is most successful when your body is ready for high-intensity sessions. Understanding how your autonomic nervous system works can help you time it right.

Polarized training is all about building duration without incurring high stress. Where does your steady state break down and what can you do about it?

Intensity can be a slippery slope for endurance athletes—there is a temptation to push harder and longer. The real recipe for performance might entail some new priorities.

To truly polarize your training, you need to focus your training in two key zones. Coach Trevor Connor explains how this works for the sport of cycling, but the physiology applies to all endurance sports.

Most popular training methods claim to build your aerobic engine, but the training to achieve that goal will look and feel very different.

Polarized training is a case where science hustled to catch up with real-world results. Coach Trevor Connor explains how sport science misunderstood the physiology and inadvertently shifted the focus toward high-intensity training.

Running coach Ryan Bolton shares three key workouts for runners who want to polarize their training.
