There isn't. Look up the WAVA age-graded results for running, or any endurance sport, for that matter. There isn't a huge dropoff until the 60+ age range. At 40-50, the dropoff is small enough that you can likely outperform your younger self with superior training unless you were training at pro/elite level at age 18-30.Age graded results reflect the best performances of talented runners who can still train at a relatively optimum level. We've all known the exceptional runners, men in their 60s or women in their 50s running sub 3 hour marathons. They are, by definition, the exceptions upon which results are indexed.
The ability to train and race as effectively as the top veteran runners isn't matched by many of us. Age-graded stats do not represent an accurate linear decline for many, possibly most, of us. Particularly so for a weight-bearing sport like running.
