I will be 65 in 2 months and am aiming at a 5k in 41.10 which would be a age grade run of 50%.
Just done my 14th parkrun at the weekend with a PB of 44.45.
I have only managed to run it all the way once, it is usually broken up by fast walking inbetween the running to get 5k done.
On the days I have been training outside or on the gym track I have been aiming at running 5k . I seem to be able to run nonestop on the inside track, but lots of run walking outside.
Just wondering if I should be concentrating on only running 30 minutes on these days, and aiming to get my pace better in that 30 minutes instead . And just leave the 5k for the parkrun days.
