Threshold Power Test

So yesterday I did a threshold power test to check and see if I have increased my FTP (functional threshold power) since last fall's lab test. This number represents the power I should be able to sustain for a 60 minute time trial. After a warm-up, and a few small high-cadence and all-out intervals, the main part of the test is a 20-minute time trial. 95% of the average power over this interval is my new FTP.

New FTP: 247 watts
Old FTP: 235 watts
Increase in FTP: 5.1%

This is a great result given that my base training was never targeting specific increases in my threshold power. Over the next few weeks, my training will be targeting this specific system, so we should see further increases in this number.
