Slow progress on the sub 35 10k plan

[TheEd]

Hi Dan and welcome to the forums

thanks for all the solid feedback and info

you more than welcome to add heart rate data in the future if you want

your 10k times are quite consistent and if anything, you should consider looking to improve your 5k time when you have an opportunity, the closer you are to 17 minutes, the easier the sub 35 becomes

if you run sub 17 then all sorts of faster opportunities can come about

you have it right with the 120 to 140 bpm for the easy runs

lets have you do a 4k time-trial and look to have you running faster over 5k while on the program

over to you
