Super cool scenery. Really great trail race and organizers really did put together a awesome swag bag! Problem is a good portion of it is single track on a cliff and out and back, so you really get slowed down! Many runners were pretty obnoxious and just pushed runners out of the way. Maybe next year timer controlled entry or something so as to stagger runners? With timing chips on our bibs we really don’t need to all start at the same time!

I absolutely loved this race! Incredibly challenging, especially when you have asthma, but such incredible views you forget the suck. I’ll definitely be doing it again!!
Easy check in, great race swag (including a super cool retro bag) nice volunteers, great course markings and yummy after race treats.

Challenging race with some tough inclines! Organized very well and is a lot of fun and a great way to test yourself. If you’re running the half, make sure to bring a camelback or water with you. There’s not a lot of places to set up water stations and it can get pretty hot out there! Can’t wait until next year!

This race will challenge you but you will be rewarded by the scenery and by simply crossing the finish line. The swag and medal is always top notch. I will make this race a tradition because I really enjoyed it.

This was my first trail race and it was both challenging and fun. The scenery was great, the hills were tough, weather was great, and the course support was top notch. Also, the communication prior to the race was clear and well organized. Course map, parking instructions, and checking information was simple and easy to understand. I will for sure to this race again and see if I can beat my time.

Can’t wait to do Spacerock again! Except for the start and finish, it’s all single-track. The Black Hole segment is pitch dark. Have blind faith there are no trip hazards (or have a headlamp). Mile 5 of the 10K is all uphill! So fun and challenging! A great way to start the day! Beautiful views of Vasquez Rocks Park. I don’t normally wear purple; just showing my support for a smallish race event of 450 total participants. Catch it if you can!

I have run every single Spacerock and loved all of them! The iconic setting alone is worth it, but the fun and friendly atmosphere along with the smoothly produced event make it that much more enjoyable. This is the one event I make sure not to miss!

I love this run – the location, the celebration, the trail – and since I am still healing a bad knee, I wanted a trail I knew. Just the 5K, but it was a challenge on that knee, and as always, I enjoyed every moment. Scenery is great, management great, and the crowds that come for this race well that says it all. We will be there next year – keep my 100% attendance record going.

I did this race with my dad who is 74 and he struggled a bit with the downhills because of his knees. Prep: He hikes 5 miles daily and I do one 9mile hike per week. Overall, we got through it, slower than everyone but made it. DO NOT do not do this hike if you don’t walk/hike/run regularly and please drink a lot of water.
SHOUTOUT to the volunteers: allllll of them were super nice, helpful and encouraging.. there were drinks and snacks (especially the potatoes) at all stations and the finish line medal was worth it all.
overall – I plan on doing this hike again next year.

This race was awesome, but it was intense. The climbs were no joke, and you for sure need to carry your own water and energy shots because the nature of the trail prevents them from having a lot of aid stations. It’s also long, my garmin recorded the course as being 14.1 miles. That being said, I loved the views, the vibe, and the challenge. This race was exhilarating, and I really look forward to running it again when I’m better prepared.

This was a crazy fun race. First trail race and first trail 1/2 marathon. While I trained, I had no idea what was in store. The first uphill was crazy, the narrow trails were narrow- even had to find a wider area to let someone pass. The high winds didn’t make it easier. That didn’t stop me, or any other person. Great views, wonderful scenery, lovely people and volunteers. Due to my speed and slow downs on the trail portions, I was over time. There were still people at the aid stations and waiting at the finish line. They didn’t leave anyone on the course. Even the photographers were at all the picture points. Everything about this race was great.

This race was my first trail run. Well organized. The terrain really did kick my butt…but, I do these for fun, to keep myself active and challenged but not to be the best. Beautiful scenery. I will do this again. Just be prepared and wear trail running shoes (I am glad I did) I seen a lot of people in just tennis shoes and one guy with NO SHOES! crazy!

Well organized. Beautiful/visually interesting course. Really nice swag and include something special for legacy runners. Very fun event! Our Foothill Flyers Running Club participates every year. Had to step down to 5K due to Achilles tendinitis issue but should be back to 10K again next year!

This race is a tradition for me and my two sons. The course is challenging but doable. Both the volunteers and runners are friendly and supportive. The scenery is like running on Mars (at least in my imagination).Bonus- this race has the best T-shirts and finisher medals.

In 2016 I did my first ever trail half. It was hard but had an awesome day. I didnt do it for time, I did it for fun. Everyone was great. Aid stations were the best. This year 2019 I downgraded from half to 10k because of foot issues. The 10k race was still awesome. Can’t wait til next year.
