Join Colorado’s biggest and boldest Memorial Day tradition at BOLDERBoulder!
Named “America’s All-Time Best 10K” by Runner’s World Magazine, it’s the participants and spectators that make BOLDERBoulder the best 10K in America! The course, over a mile above sea level, winds through Boulder’s neighborhoods, downtown and finishes at the University of Colorado Stadium. The course is packed full of energy with dancers, music and entertainment around every corner. You like bacon? Waterslides? Hula Dancers? Us too. Cross the finish line inside Folsom Field with tens of thousands of people cheering you on. Then watch the Pro Race finish and grand finale Tribute.
The Perfect Wave Start: We invented the wave start in 1983 to space everyone out and put similar speeds together, so you can go your pace and have the time of your life.
BOLDERBoulder is one of the largest Memorial Day Tributes in the U.S. The ceremony honors all of those who have given their life in military service to our country.
Almost 1.2 million runners, joggers, walkers and spectators of all ages have gathered over the years to create a spectacle that defies description. Olympic medal winners and hopefuls, grandmothers and kids, running enthusiasts and one-race-a-year guests from all over the world come together at the foot of the Rocky Mountains to form one of the sport’s truly unique events. Each year we host 50,000+ participants and 70,000+ spectators at Folsom Field for the biggest and best Memorial Day celebration on earth.

Very well organized and did not feel crowded despite this being a very large event. Boulder is a wonderful town to visit and the temperature was comfortable in May. This was a bucket list race for me and it did not disappoint!
The best 10K race in the US!
A huge event, with 50,000 runners racing around the streets of Boulder. Is it an easy 10K? Nope! Does the altitude suck? Yes! Are there an necessary number of hills? … MORE
A huge event, with 50,000 runners racing around the streets of Boulder. Is it an easy 10K? Nope! Does the altitude suck? Yes! Are there an necessary number of hills? Sure. But is it an amazing spectacle? You bet! Don’t do this for the PB, do it for the fun of racing and that stadium finish.
Okay 10k but not the best in colorado
Things I liked: Good mostly flat race, few hills but nothing to bad. Good college atmosphere, people giving shots, beer, slip in slides, dressing up. Not bad swag. Get to … MORE
Things I liked: Good mostly flat race, few hills but nothing to bad. Good college atmosphere, people giving shots, beer, slip in slides, dressing up. Not bad swag. Get to finish in the stadium.
Things I did not like: start line not near finish line, I don’t mind this for some races but this one is in the city and would have been better to start and finish in same general area. Too many people, walkers were all over and didn’t know to move over so it was a lot of dodging people to keep jogging. There were no medals. Boulder is not that pretty of a city compared to so many other areas in Colorado.

This was a beautiful scenic route! The crowd support was top notch and the finish festival was awesome, free beer! The weather was great, a little cloudy and chill but not cold. The whole town comes out to support the runners!

I was just glad to be able to run in a non-virtual race! The t-shirts were oh so soft, and the swag boxes were a nice touch. They did a great job given the changing policy landscape for holding events. I chose the Erie course and enjoyed the overcast skies, green views, and open spaces. Best part of all – I got a 10k PR. Can’t wait to run this race on the original course next year!

This has to be the most fun race in the country. There is a slight hill in the beginning and towards the end, but the rest of the race is downhill or flat. There are tons of people everywhere cheering you on and tempting you to stop for all sorts of wild and crazy shenanigans, some are well worth stopping at. My only caveat here is that this race is run at altitude.
Most Entertaining Race Ever!!

This race of full of entertainment from start to finish! I loved it. Packet pick up is a bit chaotic. It was fun to visit the area a little bit and have the expo outside but it was difficult to find parking. After getting to the bib pickup it was a breeze. Event is very well organized. It’s massive! Start waves are right on que and perfected. Be prepared to be very distracted this entire race. There is so much going on, so many people. The finish line though the CU stadium is extraordinary! A stadium full of people cheering you on. Then getting to watch the elites finish. Amazing. You’ll love this race. It’s for lots of fun. Don’t forget your cupcake at mile 6. It’s delicious!

Not my best race but it was hard to stay focused and maneuver around all the people who would stop and walk, take selfies, and be part of the shenanigan’s happening on the sidelines. I know that is part of the race, so it didn’t upset me, but if you are looking for a PR definitely try to get as high up on the waves as you can! On the other hand the race was well organized but the swag was a little weak (no medal) and you had to pay for lunch otherwise you just got a few snacks. You did get a beer though, which is always a plus in my book. 😉

With 50,000+ runners, there was a smooth start due to the multiple waves. The course was mostly flat winding through the city of Boulder, but I was not used to running at 5000+ elevation. I thought arriving a week early would do the trick, but I still ran around 2 minutes off my PR. The race ended in the Univ. of Colorado stadium, which was a unique experience. There were lots of booths set up outside the stadium with free food, drinks, and other stuff. There was an elite runners team race at the end, which we could watch on the big screen and see them finish once they entered the stadium. Finally, there was a Memorial Day ceremony that included paratroopers from each branch of the military parachuting into the stadium. Overall, a great experience and we were out before 1 PM.
Wonderful 10k with 50,000 others
This should be a bucket list race. It goes off in waves, so it's not really crowded. The spectators are awesome. Finish is on the track at U of Colorado. … MORE
This should be a bucket list race. It goes off in waves, so it’s not really crowded. The spectators are awesome. Finish is on the track at U of Colorado. There can’t be many 10k’s that are a better venue. Altitude will get your attention however. I’d say about 39 seconds a mile difference from running at sea level. They go 15 deep in age groups and not 5 year groups. Each age is a different age group, so pretty good chance to medal if you run hard. They also give a special award for anyone who can run it in a time less than their age.
