Trail running in the dark/at dawn

I have been trail running in the various regional parks for many years now during the day or just after dawn. My schedule shifted last year, and since then, I have been running with my headlamp during the wee hours of the morning and at dawn. It's sort of spooky, sort of surreal, and drenched in solitude, which I love. However, a recent sighting of a mountain lion in our front yard in the Kensington hills has me thinking more about their presence in the regional parks. I had seen one before in Redwood RP years and years ago, but never thought much of it. Then I started reading more about their habits and got a bit worried about my current regime. They are most active between dusk and dawn, and obviously harder to spot during this time as well.

I run by myself. I do wear a strong head lamp and just purchased an additional blinkie light for my body and a yellow reflective vest, but I now run with a sense of trepidation that I never had before. It kind of puts a damper on an experience that was always calming and liberating for me. I have spoken with the RP people at a few of the parks I run in who report that there have certainly been more sightings of mountain lions in recent years, but that this is due to increased usage of the parks by people rather than a growth in their population (the mountain lions, that is). Are there others who run the trails at this time? Or who don't because of a similar apprehension? Thanks for your thoughts.
