i took delivery of a lactate pro 2, to try and better identify my LT1 endurance zone, with the recent hoopla about it. i’ve been doing lots of efforts at about 0.75 for up to 3 hours keeping my heart at or below the 70-80% of max, and that worked out at about 210 watts, working off a traineroad FTP…

wattage at actual breakpoint or up to 0.3mmol above baseline. 2mmol as a fixed value is really outdated for over 30 years now.

This is my latest home test, I put myself at ~270W for LT1 [La Test]

ok, so trying to understand a little further. when i 1st got the meter, i tried it out on the sofa, before eating dinner, and got 1.8mmol. so in my test, 160watts gave 1.2mmol. should i have measured lactate at rest before the test? does “from base” refer to at rest, or the lowest point measured.? …

Always start testing after a proper warm up. Otherwise the first datapoints may be elevated. I always ride at least for 30min before i test. Took this advice from evil Dr. Ferrari

Sryke has it correct as usual. To reiterate some points of testing: You need a long and slow warm up to give the aerobic systems a chance to get firing and equilibrate. You’ll typically see lactate drop and then stabilize during the warm-up. Well trained athletes should see values under 1mMol. I…

@DarthShivious thanks very much for your reply in such detail. you’ve offered lots of hard learned advice there. the 1mmol above base is what i’ll reference. certainly 200- 210 watts feels right on the road, and last weeks 3 hr ride at a steady 220 watts was just on the other side of that, despite …

These are great tips! :pray:t3:

I found the tweet from AC about where his Z2 is. On another thread ISM agrees that that is basically his Z2 in the absence of a met cart test. [image] Alan Couzens @Alan_Couzens Since zone conversations can quickly go off the rails due to differences in definitions, here's what I mean wh…

When you are doing lactate ramp test, which HR are you using? Max HR in ramp step, or avg? If the step is just 6min then using avg is probably too low or?

For reference, we have a thread on the forum where several home testers have contributed their results and tips. Link below. I’m due to run an end of season test myself and have just been lazy about it.
