Oscarr - re max HR.
Your biological age may have nothing to do with your "running age" as you are no doubt considerably fitter than your "standard" 60 yr old!
That said, the pundits all seem to agree that the only thing you can do with a max HR is watch it decline as you age!
FWIW my fitness test (on the treddie back in Jan 13) was stopped after 24 mins when I was running at a pace of 6:02 min/m in other words flat out.
My HR at that time during the test was 160 so if that was 95% effort then max is 168; if 90% effort then max is 178. I happen to think my max is 182 after a series of hill tests (and I was tired going into the treadmill test).
Conclusion: for you.....168/180 would be a fair spread if I was a betting man, and could be a fraction higher as you are younger than me.
