I've had virtually no time to drill, or even ride, for the last couple of weeks. I rode a technical trail last Thursday & felt that I had lost some of the muscle memory that I had started to develop when I was drilling regularly. We rode the same trail again yesterday, but this time I did about 10 minutes of drills immediately before hitting the trail. That 10 minutes was all it took to reawaken the muscle memory so that the technical sections were much easier to negotiate.
