There is a lesson I learn't very quickly when I first moved to the alps. No riding buddies at first but there was no way I wasn't goint o get out there (Italian lakes area so not a busy uplift resort area). I had a stack while riding something I shouldn't have attempted on my own, 3 inch gash on my forearm followed by 1.5 hours riding down an alp with my riding shirt as a bandage (this was 10 years ago), through town traffic and straight into casualty!.
What did I learn:
-Body armour (especialy arm pads) are cool
-First aid kit v.important
-Most importantly: when on your own ride within your limits and take more conservative decisions on what is ridable and what isn't. Take easier line choices or god forbid walk the most techie sections - the time for risk taking and pushing it is with a group - end of.
So I would say yes, ride on your own, take a first aid kit, be conservative with speed and line choice, reign in the adrenaline and concentrate on riding smoothly and in control rather than on the edge. Basically get down in one piece!
