Absolutely. Something happens during a bike marathon where my body and brain are eventually independent of my thoughts and I'm moving on autopilot with mild tunnel vision while thinking about complex thoughts, old memories, things I could have handled better. I can only attribute it to persistent eustress and the post-metabolic state of endorphin saturation combined with adrenaline.
That's exactly the state I get into on a long mountain bike ride. Right before I have a crash!
Which is to say some sports have a way of forcing you back into the present moment. It can actually be a good thing for those whose minds tend to wander.
Anecdotally, I find that I come up with ideas almost every time I'm on a long drive. There might be a shared mechanism, whether that's something related to navigation or simply an inability to occupy oneself in a way other than thinking.
