Trackhead, did you ever ackknowledge that your charts were wrong for LT pace???
And lets not use terminology as the excuse. Maybe incorrect understanding of terminology is an issue, but... ( I mean , if you want, you can call "LT pace" the pace one runs an ultra-marathon at. It would be wrong, but you could say it)
LT / AT / LASS.......
for MOST people these terms mean: the point in time when your blood lactate starts to increase quicker than it is cleared, the point where the fairly steady slope upwards on the chart listing this accumulation of lactate begins. It is often concurrent with VT. Now you can argue the threshhold occurs right before the lactate starts to accumualte, or just after, or right at that exact point..... but lets not get into semantics and minor differences. There will always be a RANGE of several seconds for this thresshold, but the important thing is for people to have the basic understanding of this pace.
JTUPPER WROTE:
"A pretty good estimate of threshold pace is about 24 seconds per mile slower than current 5k race pace." Others use (Tinman?) 5k pace / .93. Others say the pace around 10mile-1/2 marathon pace.
Tergat is a PERFECT example. His 5k pr is 4:07 per mile. His 1/2 marathon is 4:30 pace. That’s 23 seconds per mile difference. Now some might say is threshhold is just quicker than the 1/2 marathon pace. Use the .93 formula and you would get 4:26 pace. This all fits together with the previous definitions. So Tergat’s threshhold is between 4:26-4:30 pace.
His marathon WR is 4:45 pace. THAT IS NOT HIS AT/ LT / LASS pace. But based on your chart, Tergat’s LT pace would be SLOWER than his marathon pace. Just not true.
People are confused enough about this. As others mentioned on the thread, the pace YOU listed at "LT pace" is really around "marathon pace." And again, that is not by any standard scientific or coaching definition "LT pace." Calling it " this LT pace" is just playing with words and causing more confusion than necessary.
Maybe you retracted this later on, but I never saw that.
