Mike McCormack has been instrumental in getting me to perform better than ever before. I highly recommend his training at M2: Triathloncoach.com.
His general philosophy is one of quality versus quantity, and judicious use of periodization and interval training to improve fitness and performance. Amazingly, most of his bike training is indoors on a computrainer which allows controlled and measurable improvement, versus junk miles on the road. Even the treadmill is a useful tool to train hills versus finding the exact right hills to run up and down outside.
Given that it’s winter in northern California, this is critical to have training resources indoors, especially given the monsoons that we’ve been experiencing lately.
