I was feeling the same way a couple of weeks ago.
My plan was to start ramping up the training intensity on January 1st in preparation for our first races in the end of February. After one week of 3x20', 2x20' and etc, I just could not get motivated or focused anymore. I was having no problems eecking out the power, but the motivation to do so just isn't there this year.
What has got me motivated the past two weeks was to dump the trainer, dump the powermeter and HR monitor and do all my rides either on the rollers or outside. With my work and family schedule, all my roller rides happen in the evening when I get home. All my outside rides take place on the weekend. The goal is to reach 1,000 miles by my first race on 23 February. That single goal is enough motivation to get me moving...I go fast when I feel like it, and slow when I need to catch my breath.
