Running 2:30 marathon at age 51, which he did at Chicago last Fall, age grades to 91.7%. How many men 50+ are age grading over 90%? Not that many. So yes, that’s fast for age 51.
Wrong calculator.
His Chicago result is 89.83%.
The half at age 50 1:10:55 is 90.62%
What times will he be running by age 60?
Fun fact: M60 half WR is 1:11:31 set 10 years ago.
Honesty, I think it is a little tougher to hit those %s training for an 800. You certainly get more notoriety doing it in a marathon though at that age. At age 52 an 800 in 2:06.78 is a 90.62%. He wouldn't have the leg speed for that.
M55 800 national leader is 2:05.71- 93.54%
Really at Masters national level 90% is competitive, but even a 90% may see you finish out of the medals in certain events
