I wasn't going to publish these, since I seem to be going backwards. My excuse is that the test was at the end of a training block, and the block was disrupted by a week off the bike due to snow. T30 results were 256 watts, T60 was 245 watts. Weight was down to 66.2 Kg, so I'm holding around 3.86 watts/Kg.
As punishment, I'm starting under/at/over intervals where I do 2 minutes @10% under AT, 2 minutes @AT, and 2 minutes @10% over AT. Repeat until overcome by nausea.
