My Beating Heart

Today I did a Lactate Threshold (LT) test. For those of you who don't know what that is, but would like to, here is a link to a great article--LT Article

The test I did was similar to the one in the article. I warmed up for about 15 minutes, and then, beginning at 5.8 mph, upped my pace by .2 mph every 2 minutes, until I felt I could go no longer. I made it all the way to 8 mph.

Once I graphed my results (using the spreadsheet I downloaded from above link), I found out my LT is 181. Now what do I do with that??

I will use that number to set my heart rate training zones, so I can be sure that I am not training too hard when I am running. I think I will find, initially, that all of my paces will slow a bit, but that is not actually a bad thing. Running at a pace that is comfortable will build up the oxygen delivery system of my body, and, ultimately, make me be able to go faster for longer!!


  1. I sooooo need to do an LT test. If I'm at an RPE of 7-8, my HR is at my max. That just doesn't feel right. I'll definitely check out the article, so thanks for sharing!

  2. Thank you for the report and the article. I plan on finding out my LT now that I know how to do it.

  3. Good job. LT tests can be tough. Let me know what your zones are.

  4. cool that you did that test. hope it helps you figure out optimal training! did u figure out you can input LT into BT and calculate your zones?


Woo-hoo!! I want to hear from you!
