Indeed. I'm 55, resting HR low 50s and it's rare that I don't hit 200 on any given ride. I can average high 100's for hours, day after day. My HR can go way over 100 just suiting up and taking my bike out of the house.
Dr has no concerns as I show/feel no problematic symptoms and my HR drops pretty fast as soon as the effort is over.
Where things have gone off the rails for me is when too hot and possibly under hydrated.
