I'll come back to the route, I've not read much about it - the Etape looks proper hard this year, might give that a go.
I'll guess we'll find out on that new training thing - training around an FTP based on a test of 20mins -5% is a massive thing of the past now anyway - my training is around weaknesses in my power duration curve - when I test each month, I do three tests in a month and all in the same week after my recovery week. One day a series of sprint-based stuff, one day a series of 30-60sec hard efforts and then a final day where it's longer - usually between 30-60mins around or above my FTP (357W at the minute).
Interesting stuff, I'm not really into any training aids yet, I'm too lazy to be honest. I rarely put the HRM on for a start!
I want to get into it and am considering at power meter when funds allow. I do find it fascinating how all the data goes together though to tailor your training plan. There is so much data available, it can only be beneficial if you know what it means.
I've done ftps on my turbo, but I'm not sure how accurate they are. Just need zwift to sort out android compatibility, apparently it is going into beta soon. Until then, it is Bkool.
