I just finished my latest race, and I’m happy with the result. In fact, I reached a new personal best in every metric. I follow a structured training plan and it has really paid off.
However, on the last event my heart rate averaged 181bpm for the 22 minutes of the race, and peaked at 196bpm. At 40yrs old I’m wondering if it is dangerous to push myself that hard. Does anyone know a good resource to investigate this topic?
Thanks for your help.
