Replying to the post "Why are my easy runs so slow?".

> The effect of running the easy runs between 70-80% of max HR vs. below 70%, like I generally recommend (and still do), is a matter again of cost/benefit. The effect on muscle tone, running economy and recovery is sufficient at below 70%, but going above this, most will start having more muscular wear. That will influence recovery and the next harder session. MOST runners will be MOST of the time be in a negative muscular state in terms of recovery and tone after a harder session - even sub-threshold. So you really have to play the recovery days smart. Are there exceptions ? Yes, of course, but usually staying below 70 generally keeps it safe.

Replying to the post "Thinking of adding 36-40x 45” on 15” off to the repertoire".

> That load is too much. For most, the top repeat number should be about 30 at threshold, 20-25 at faster paces. You also need to consider the aim beforehand - you can do it as a pure threshold session but also as a faster one. Personally I like to do it progressively faster and faster.
