I have a current 10k time of 55 minutes and I'm in training for the Helsby 1/2 marathon using this schedule
. However, I'm a bit preplexed as to what speed I should be doing the speed sessions at.
For threshold training I've been using this article
because it contains a usefule table showing different training speeds based upon your current 10K time. My problem is that in the article, Amby Burfoot asserts that I shouldn't be doing speedwork at all - I should instead be doing VO2-Max work. So the table doesn't give any figures for speedwork.
Can anyone give me any guidance ?
thanks in anticipation,
