No exercise this weekend. Shut it down for a week. It won't feel good. Lie in the sun and get some Vitamin D but don't get burned. Sleep lots. Also, don't re-roof your house or build a deck etc with your “spare” time!
Your diet sounds top notch. Log everything and check in on balance. A long term calorie deficit can run you down too.
You can kill it at Breck if you right the ship quickly now. The rebound from over-training can mean solid endurance if you really do rebound properly.
