TESTIMONIALS
Holly Baez
My 2nd time running this 10K, and it's so tough, but definitely worth it. The hills are really challenging, but I feel very accomplished afterwards.
Dennis Dyer
2nd year running this race. It’s been a great experience. The course, crews, swag/medals are…out of this world!
Kelly Elsasser
I came and conquered.
Caroline Castillo Shahin
This course is the toughest. Challenged me since the end had more hills than in the past.
Wendi Anderson
Vasquez Rocks offered an amazing backdrop for a very challenging and fun race. The volunteers and positive race vibes were awesome!
Candace Gonzalez
Super challenging and beautiful half marathon+ race.
Evelyn Brown
One of the "funnest" local races in the LA area! I do this every year, and see pals from across running clubs, across communities, some friends I see only a few times a year, and I make some new friends every year. With no age group awards, the pressure is off and I know that any goals to achieve, other than climbing that last dang-blasted hill, are those that I have set for myself. So, I get to enjoy the scenery at every turn and every elevation.
Sirous Shahin
It is a dream and well-organized race: the race course, scenery, participants, aid stations, and overall finishing reception were exceptional.
Charity Pierce
New Global Adventures are the best they have excellently done above and beyond in every aspect of race directing. They are friendly and warm with each and every person they come in contact with.They make sure that I feel valued and I appreciate them very much.

Awesome race!
Karen Reel
This was a well-organized race from start to finish. The color-coded race flags were well placed, and the volunteers cheered us on when it was hard. I liked the 20-minute spacing between groups so that friends of different races could finish around the same time.
Bruce Kromray
Awesome!
Jonathan Andrade
I'd only ever heard about SPACEROCK before finally signing up. So glad I did! I've been missing out for years! We'll definitely be back next year. The vibes were out of this world.

Strenuous trail with natural obstacles such as, sand, grass, dirt, small and big rocks, hills and slippery downhills. And of course, the scenery is magical. Next-to-last, great race volunteers! Thank you.

Erick Munoz
SPACEROCK is a great race, and is put on by great people.
Peter Noyes
It was a very well run race and a challenging course. Normally this quality of production is found at much longer events so I was very pleasantly surprised.
Sandy Adams
After running SPACEROCK each year, sometimes 10K, others 5K, and even the virtual, each time it has been an experience I can't wait to do again. This year, not far off of knee surgery, it was more like rehab time, and even so, I would do it all over again, even with the balance issues. YES!
Felix Martinez
It is a great experience!
Darren Phan

I have run every race since the inaugural race. This year’s 10K was a butt kicking race! Single track and technical. I liked it. It was fun to know what was coming on the second loop.
Neil Viray
The SPACEROCK trail, it's difficult and challenging. It's an extra ordinary marathon.
Catherine Christ
By far my favorite race, it's so challenging but so fun & rewarding. I love the volunteers and love the course. Everyone, runners and volunteers alike, are so kind and happy. The whole process, from getting your gear to finishing the race and follow up emails & photos are just amazing and makes me want to come back year after year!
Tiffany Lamb
Spacerock Trail Race is no joke. This is not a casual race to just get out there and run. You NEED training and you NEED strength to climb. But it was the most fun and welcoming race I have ever done. I felt like part of a race family and it was my first time ever. Each volunteer was extremely supportive. The course is very well marked and the aid stations are very nourishing. Very well put together race and super informative emails sent leading up to race day.
George Bock
This was my first time running Spacerock Half Marathon and it did not disappoint!!! It was everything I was expecting and then some. Beautiful location, VERY challenging and great people and am looking forward to next year.

Luisa Rivas
Spacerock gives you a majestically feeling as if you are in Nirvana!
Laurie Hendron
Finally got the chance to run SPACEROCK Trail Race Wow.wow.wow. So challenging - the climbing was intense! But at the same time, it was gorgeous with such interesting terrain. And there was some downhill single track that was a blast! I highly recommend this race .
Thomas Post
Epic trail run. Challenging terrain and beautiful rock formations everywhere you look. Those last 2 miles hit like a mo fo… It ain’t over till a dancing dinosaur gives you a high five!
Roy Peterson
Having climbed those hills the past 3 races, I volunteered this year as I regularly volunteer at Valencia and thought I would see how things went at Spacerock from the other side. I had a twinge of jealousy as the runners came across the finish line. But the volunteers I met and the excitement as I was able to cheer on the runners were more than enough to overcome that twinge. New Global Adventures puts on the best races and I look forward to being a part of them for many years to come, both behind the scenes and on the trails.
Louis CoffeeMeyer
I mean, homemade mini-cookies after the Mega Hill? I'm already signing up for next year!
Lara Ray
If you're looking to challenge yourself, then you've come to the right race. Steep hills, single track trails, dark tunnels, unpredictable weather...you need to come prepared for anything and everything!
