Maximum Heart Rate?
I always wear a HRM while I'm riding. I ride 3-4 times per week including a club race on a Thursday evening and a National race (at Sports Level) every 2-3 weeks. On just about every ride my heart rate maxs at 175 bpm (never higher) - can I assume that this is my "Maximum Heart Rate" for training purposes? I'm 48 and fairly new to MTBing.
