PM: 3 hours on the trainer. 182W. HR 127.
Endurance + Sweet Spot 3 x 12'
Long ride with some lactate testing. Warmed up for 20' @ 155 (HR 101). Base lactate was 1.5 mmoles. I then did some mid-range zone 2 work 30' @ 172 (HR 120) 2.0 mmoles, 30' @ 179 (HR 123) 1.3-1.7 mmoles, 30' @ 187 (HR 124) 1.5-1.6 mmoles. That took me to just about the 2-hour mark and then I did 3 x 12' sweet spot, targeting around 240-245 watts, while keeping lactate under 4 mmoles, but hopefully over 2.5 mmoles.
242 watts @ 150 BPM @ 3.6 mmoles
240 watts @ 152 BPM @ 1.9-2.2 mmoles
243 watts @ 157 BPM @ 2.8 mmoles
I am unsure if the lactate on interval 2 was right but I did two tests, so I think it was on. I think the recovery was a bit long after the first one as I was fiddling around a bit. This was definitely one way to break up a three-hour training ride.
