Running

Okay thanks will look into a ramp test. Just wondered if it was normal not to get past 'tempo'.

Any HR randomly assigned to you is going to be pretty meaningless - Tempo for you may be taking it easy for me or thrashing it anaerobically for someone else.

It's also possibly that you haven't pushed yourself as hard as you think - with a ramp test, you can get the nasty bit (and they are nasty, if you do them properly) done and out of the way, but also reflect afterwards as to whether you could have gone longer.

(I do get monitored every couple of years but have been told there's no impact on me exercising - can continue as normal).

I'd be erring on the side of caution, and having that advice put in the context of maxed out efforts.
