Trainerroad's estimated power gave me an FTP of 177 Watts, which I feel is a little low. It's by no means an exact science.
A lot of it is down to the crapness of riding indoors.
Trying to increase your endurance with 11 days to go is pretty pointless, more so for a 10.
Being a 10 so you're better off getting your body used to VO2 type efforts and leaving enough time before the event to recover from them, ie. don't do them the night before.
I bow to your supperior knowledge in this.
But I was more thinking about getting a feeling for the 'suffer level' that should be maintained. To better gauge effort on the day. Rather than build the bodys ability to maintain effort per say.
When I run a half marathon. I train 5km intervals to increase pace. Then closer to the day I do a few say 12km runs to get a feel of the effort.
