another thing to look at along the burnout lines is time off the bike. I just looked at my schedule and I have already had 20 days this year where I did not touch a bike, and I consider myself on a hard schedule this year. Everyone is different, but it is also possible you are trying too hard. I go 2 weeks full on each month, one week mostly off, and then use the 4th week as a variable, hopefully it is on, but if life gets in the way, I let it.
