What Runners Are Saying...

Our races are all about the participants, runners, and volunteers, the experience they have with our race. After every race, we do a feedback survey to help us understand how we did, how we can improve our future races and hear what the runners and volunteers thought about their experience. We got a ton of responses and great feedback, overall it is clear that everyone had a spectacular experience.

But don't take our word for it. Read a few of the testimonials below directly from the runners. They are grouped by each distance, 5K, 10K, and Half Marathon.

Huge thank you to everyone who participated, this race would not be possible without you. SPACEROCK ♥ you!

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 definitely took trail racing to a whole new level.

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!
