Why are my easy runs so slow?

Hey everyone, Stats: • 30M • 2 years running, 2.5 months doing Norwegian Sub-threshold training (MSA) • LTHR: 173 bpm • Max HR: 190 bpm • 65 km/week (40 mi) → 2 easy, 3 sub-threshold, 1 long run • 5K PB: 18:45 (3:45/km | 6:02/mi) • 10K PB: 39:45 (3:58/km | 6:24/mi) •…

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…

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.

Thinking of adding 36-40x 45” on 15” off to the repertoire

Do you think the reps should be done at or around 5k pace or closer to 10k pace?

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…

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.
