That's a high heart rate! But I'm certainly no expert. I come on here to share my experiences and get excellent free advice from people like @Stuuuuuu and @inchy14.
For the record, I'm 59 and have been running for 18 months, purely for enjoyment and fitness purposes. It has helped me get from 17 stone to 13, though dieting was the main reason for this.
I can do long runs. I managed 14 miles on Monday, ascending 500m in total. I hate running in rain and up hills, and the anaerobic zone is my enemy. For the record, I pushed myself up a steep hill today and managed to get my heart rate to max out at 171.
The best advice I took about running was from here, and it was to run at a conversational pace. Since I started doing this, I have enjoyed my runs much, much more than before.
And less injuries I suspect?
