So I'm 35 and running faster now than ever before. I was a decent high school guy (16:45), never ran in college and got back into running in my mid 20s. In the last year I finally broke 16 in the 5k, and I also ran sub 73 in the HM.
Just wondering how many fast years I might have ahead. Is it reasonable to run PBs at 40 and 45?
At what ages did you run your best?
