Happy to share the file, although you might be better off getting the one from the 2017 race. The 2018 race was shortened by 3-4 miles, and overhearing the race organizers I had the strong impression that this was somewhat unintended and that going forward they would be adding it back. There is a small loop right after the Radford climb that was taken out. My advice would be to look at the posted results from 2017, then go scope out those riders’ Strava files. Flyby can be a good tool for this too.
It sounds like you are right where I was a year ago, just wanting to survive. If I could go back in time and give myself some advice, it would be to accept where your fitness is now, but treat every other aspect of it as a race. You can learn more about strategy this way that will still be applicable when your fitness improves. Most importantly try to minimize the time spent stopped. Should you continue with these types of events, you’ll be able to better compare your fitness gains this way. By way of my own personal example, I spent over 22 minutes stopped at the Grizzly last year, and only 4 minutes at Leadville (and that should have been closer to 2).
