Calculating LT1 and LT2 approximately without a blood test?

@kurt.braeckel

Your actual 5 min MMP is almost assuredly higher than your 5-min power from a ramp test, and likely by a significant amount.

A lot of 3-4 minute results in this thread:

Fun with TR training analytics...what's this number for all forum members?

Take your best 1 minute power from your last ramp test. Now go to your ‘personal records’ page and place your cursor on the right hand side of that chart…move the cursor from left to right on the chart until you see the 1-minute power number from your last ramp test… What’s the duration? In other words, what’s the longest you’ve ever held an average power that equals the best 1 minute power from your last ramp test? For me, IT AIN’T LONG! 3:32.

but context is everything, so maybe if someone went out and targeted a 5-min all-out the feedback in that thread would be different.
