Subject: RE: Slow is fast: 5 weeks at Zone 2 great work.
Doing Zone 2 work is really designed to improve your sub threshold performance, rather than specifically raise your LT. Your LT can actually drop if you are donig strictly Zone 2 work, since you are avoiding HR zones that would stress your energy systems right around LT.
The reason to do repeat indoor testing with HR only is to make sure you are still training in teh correct zones, but you may or may not see an increase with LT with only Zone 2 training.
What you WILL see with only zone 2 training is increased pace and or decreased effort at the same sub threshold HR. In otherwords, even if your LT doesn't change, your sustainable speed should improve.
There is no good or bad LTHR, except in the sense that the closer your LTHR is to yoru HR at VO2 max, the closer you are to your potential.
So keep up the good work, and as soon as you get outside, be certain to also measure speed/distance during your LTHR testing sessions.
Also, even though yoru biking training is not muscle specific to running, you are still training your heart's abilility to pump blood to ALL the muscles of the body, so it's not surprising that your run performance should improve as well. But like somebody above said, if you want to improve yoru run specifically, you need to focus on that activity and do separate LTHR field test fo rthe run.
In all, great job, keep up the consistant training & blow everyone off the course on your next event! |
