Review
Very well organized race and absolutely stunning scenery. Plenty of water/Gatorade available on the course and everyone was extremely friendly.
Race Tips
The only thing I wish I had done differently was to hug the paint line more on the second half of the race. I did a really good job not adding distance the first half of the race because I ran the tangents on the gravel portion really well, but I somehow added on almost 0.7 miles of running in the second half of the race. Be ready for your quads to be torched by the end with all of the downhill.
