I agree with everyone who said to take a few days off. 10 months of training is tough (you did take some rest weeks in there didn't you???) and a few days off will only help, not hurt. See how you feel after that, I bet you will be stronger and faster than ever.

Since your goal is to peak for this one race (is it a MTB race?) you should taper anyway. After a few days off, ride easy one day, do a couple of days (not back to back) of intensity but maybe do half the number of intervals you usually do in a normal training session, ride easy again, and do a pre-race ride the day before your event where you don't kill yourself but you get a few "race-pace" efforts in. You'll be fine!!!!

I trained and raced for 9 months (jan-september), and soon as my last race was over, I was DONE physically and mentally, so I totally feel your pain! Now I am riding 3-4 days/week, but my rides are (mostly) unstructured fun including some long rides with friends. It is the reward for a tough season that you will be able to enjoy AFTER the excitement of your race!

Good luck, and have fun!
