21km - sub 1:25

[daniel_radz]

Hi daniel and welcome to the forum

which 10k program will you use to achieve this, if you would like to run a sub 85 minute 21k you need to be able to run below 40 minutes for the 10km

so best thing to do would be run a 4k time-trial and we can work on things from there

all the best

thanks Ed

Will do the 4km time trial this week
