I'm 44 years old and have been riding for 3 years (2 seriously). During the season I train 12 hours a week (about 250 miles). This winter I have been training 8 hours a week on a fluid trainer at a PE of 7 (out of 10). Three months ago I had to take a week off because of the flu. Since then I've been back on my 5 day/8 hours a week schedule training pretty hard for 3 months straight with no recovery rides. This morning I woke up and did not feel like getting on the bike. Should I take some time off or continue to work through it until I get motivated again?
