Discussion: Threshold

How do you define it for these type of workouts?

I use 5 intensities for my training:
1 - easy
2 - moderate
3 - threshold: at lactate threshold (or aerobic threshold) - point where blood lactate increases from resting levels.
4 - tempo: just below/at lactate turn point (or anaerobic threshold) - point where blood lactate exponentially increases/passes 4mmol
5 - VO2 Max: above lactate turn point

So the ints in this one are at intensity 3 or what I call threshold (which confusingly is what others call tempo and they call my tempo threshold...)

Fair enough, so many different terms and definitions out there for those types of paces...

Once upon a time I could do Thursday morning sessions like this....

Where do you fit on the tempo vs. threshold scale Ali?

In specific workouts I typically do what you would call tempo (I roughly define it as a bit quicker than half marathon pace or what I could sustain for an hour, but typically adjust based on HR/feel on the day). I don't formally do any of what you call threshold, but I will often run the second half of long runs in that intensity range for a solid endurance stimulus on tired legs.

Interesting, yea I don’t think a lot of people use what I call threshold (I know people who are actively against it). I don’t think it’s relevant for 10km/5km/sprint and middle distance but I find it good for increasing my aerobic capacity for long distance/over half marathon. If I struggled to recover from it I would be less likely to use it but I find them relatively easy to recover from (tempo and VO2 much harder to recover from).
