I lift year round, but like NY Biker, I back off the lower body during race season.
Recovery days help you perform better. Don't skip them. And don't cut calories if you are training hard. And sleep as much as you can. I was at the point of burning out last June. Training too hard, overwhelmed with work, not eating or sleeping enough. I was dragging a$$ in the pool during a swim practice when my swim coach told me to get out of the pool and go home, drink a beer, have a cheeseburger, see my non-sports friends and don't even think about training for three days. He was right. The three days off with sleep and some extra calories to help my body recover gave me the best two weeks of training I've ever had afterwards. I didn't lose any fitness, in fact, I broke through some plateaus that had been dogging me for a while and seriously PR'd my next 10k race.
Catrin, are you hip flexors still tight? Tight hip flexors can cause a multitude of problems up and down the kinetic chain.
