I loved this race. The course was both challenging and beautiful, and the race staff and volunteers were top-notch. I can't wait to do it again next year!

Yet another fantastic inaugural event by New Global Adventures. Shuttles, coffee and awesome gear check bags at the start; challenging, well marked course with beautiful views; great volunteers, and free photo downloads afterwards. Really a fun, welcoming atmosphere too. This race hits all the right buttons and is definitely one you'll keep coming back to.

The Inaugural Spacerock Trail Race was literally an out of this world event. A very scenic, challenging and fun race that will become an annual event for my friends and I........you definitely took trail racing to a whole new level.
Melissa Cierra
This is only my second trail race and I am so glad I signed up for it. The course is challenging and scenic. It was clearly marked, thank goodness, because getting lost was a big concern for me. Luckily, there was nothing to fear. The staff and volunteers are all friendly and helpful. Participants were kept well informed, there were plenty of race photos, and of course the goodie bags, shirt, and medal were top notch! This is a great race, and I look forward to doing it again next year!
