This was my first ultra and I had a fantastic time! It was really warm for day for April but thankfully that dried out a lot of the mud. The course is a lollipop shape with the out and back in trails and the loop on gravel. There are two big hills in the trails. The race starts out on single track so where you are at 1k is essentially where you are stuck for the first 10k or so until the path widens enough to pass. It's a beautiful time of year with all the flowers blooming. Unfortunately, it's too early for the trees to have leaves so there isn't a lot of shade. If it was raining, it would be a super muddy course. The aid stations are all great and fully stocked with Clif products. Everything was really well organized and I had a great day. I'll be going back next year for the 50 mile!
