We review four recent studies from the scientific literature, addressing the hypotheses, methods, and conclusions of each to give you a greater understanding of the latest findings in endurance research.

We break down every aspect of the time trial: part performance art and part crucible for athletic and scientific experimentation.

In an age when athletes often focus on the specifics, we address the importance of focusing on the fundamentals: training, recovery, and functioning gear—the things that will bring you the greatest return for your investment of time, sweat, and energy.

Age is just a number. Few athletes know that better than Rebecca Rusch, who joins us to discuss how to adapt and perform at the highest levels of sport as you age.

Physiologist Lindsay Golich, who works with some of America’s best Olympic athletes, helps us field questions on heat, altitude, FTP testing, fasted training, and much more.

Coach and endurance mountain bike champ Daniel Matheny helps us field questions on coaching junior athletes, how aerobic capacity is impacted by intensity, PVCs, and much more.
