I did it! Managed to take almost exactly half an hour off of Marcy's time. I ran hard the last handfull of miles, since I was worried I might not make it after all. Turned out my watch was reporting slightly fewer miles, so it wasn't quite as tight as I thought it was going to be. It was a beautiful day on the trails, and I really enjoyed myself almost the entire time. That was the real goal, but it feels great to have accomplished both things. What a great way to see all these parks!
Here are my splits in reference to Marcy's times:
Inspiration Point: -17
Steam Trains: -21
MacDonald Gate: -37
End: 7:01:49 (-30:55) of course, I had fumble-fingers at the end and managed to log another minute or so before I got the watch stopped for the official time :)
I've post a run report on my Strava page.
Congratulations, nicely done Tara!
