Question: I frequently start rides within 30-60 minutes of waking up. Often this means I’m on the road at 5 a.m. My heart rate stays low for about 25 miles, but after that it reaches normal levels. Why? — Phil H.
Coach Fred Matheny Replies: I suspect that getting up and out so early means your body is still in a resting state. It isn’t fully awake and responding to riding.
According to exercise scientists, afternoon is the optimum time for a workout. By then, your body is warm and flexible from the day’s activities.
But if early morning riding better fits your schedule, keep doing it! As long as you’re an early bird, just do as you’re doing: let your body adjust to the ride at its own pace.
