This site exists because of a simple frustration: race results tell you where you finished, but they don’t tell you how well you actually ran. A 22-minute 5K means something different at 35 than it does at 65. Age grading fixes that by comparing your performance to the standard for your age, and once you […]
The half marathon is one of the most deceptive distances in running. At 13.1 miles it is long enough to punish poor pacing severely, but short enough that it feels manageable on race morning. The result is a distance with a specific and common mistake: starting too fast and paying for it between miles 9
Ask ten runners how they train and most will describe some version of the same approach: run most days, run hard sometimes, run very hard occasionally. It is not wrong exactly. But it leaves enormous amounts of fitness on the table. The reason is that casual effort-based training tends to cluster in a physiological gray
There is a story runners tell themselves after 50, and it goes something like this: the best years are behind you, the times will keep slowing, and the goal now is damage control. Train less, expect less, accept the decline gracefully. The science does not support this story. And neither do the age-grade scores of
You just ran a 5K in 26:45. Your training partner, who is 58 years old, ran the same race in 28:10. You finished faster — but who had the better performance? That question has no good answer without age-grading. With it, the answer is immediate, mathematically precise, and often surprising. The Problem Age-Grading Solves Comparing
VO2 Max is the single most important number in distance running. It is your body’s maximum rate of oxygen consumption — the ceiling on how fast your aerobic engine can run. Every training pace, every race prediction, every honest comparison between runners traces back to it. The good news is you do not need a
