Did a 20” and a 4’ interval today. Last spin before my medial meniscus repair.

I ordered a Calibre Biometrics device way back in July 2021. Finally got it just this week.


It's basically a portable metabolic cart. Does VO2, VCO2, RER, kcal/min, and thus from the last two can then break it down into kcal/min from fat and carbs, too. Also collects sundry other data.

Anyway, I gave it a trial run today, and despite some noise in the data that's likely related to mask leakage given my beard and the strap setup on it the numbers seemed plausible overall. Pretty cool little gadget that I'll play with more over time. It wouldn't be great for outdoor use, certainly not anything with jostling, but I can certainly use it on the Bike and the Tread.

Details here:

More Calibre testing. This is with 100W x 20 min, 110/120 x 5 min each, then 130W until the last 10m at 100 again. So 1.8-2.1 VO2/min is expected. The raw data are noisy but when smoothed over 5 minute running intervals it doesn't look too bad. Little spike in the data were when I hyperventilated intentionally--apparently that leads to artifacts.

did a non-easy spin for once. Took last 10’ at high Z2 diverging from the called out zones since that was enough already.

Threw in a 6 sec standing and 30 sec seated sprint tonight. Also found that my LT1 pace while jogging is about 3.2 mph. Maybe 3.1. :D yes, that slow.
