Age grading is BS.
1:11 is 1:11, can’t be compare with 58 min not matter the age. This person wasn’t able to become an elite athlete when young that’s the real deal. Please stop thinking that some amazing performances at different group ages are better than WR because they are Not.
60 y/o 1:11 does not mean he could run 55 in your 20’s.
I know an amazing 40+ athlete he wasn’t a great athlete at college he kept running and training very hard and now one of the best masters in the country and might be able to get in the future this BS equivalents at WR performances but we all know that he wasn’t able to achieve anything close to that when young and tried hard.
Please have respect for athletes at their peak even with doping it takes a very special athlete to achieve WR’s.
You haven't understood the point. 1.11 at 60 is comparable to 55min open when compared with the one mile wr i.e. 4.50 (the mile wr at 60) and 1.11 at 60 translates to 3.43 (the current mile wr) and 55min open, if each mile in the half-marathon is run at a rate of 30-35secs slower than the mile record.
