Longmont Half & 5k (LM Half)

Thu July 4, 2024 Longmont, CO 80504 US


No question is too silly to ask regardless of whether you're a rookie or a veteran.  Help us improve the FAQ Page!  Send your general or specific question(s) to and type: "LONGMONT HALF FAQ" in the subject line!

All 3W Races events maintain a cup free finish area.  This means that water will be available for refilling your personal water bottles.  Bins for holding your water bottle near the Finish Line will be available on race day morning.  Biodegradable cups will be used on the course, but no disposable cups will be available at the finish line. Thank you!

Walkers and joggers should always stay to the right, faster runners should pass on the left.  Walkers, please keep your groups down to two abreast so that others may pass you.  

Since the Half Marathon course is open for 3 hours and 30 minutes, some walkers may desire to start EARLIER than the official start time so you can return to the finish before the finish line and expo close.  You may start up to 60 minutes early, and must notify the race director in advance that you wish to do so.  

Please note that aid stations are operational and course marshals are officially on duty at the time the regularly scheduled half marathon begins and may not be operational when walkers first pass.

Can't make it to advanced packet pick up?  Send a friend, family member or teammate!  We will allow others to pick up for you.  Yes, there is same day pick up available starting 90 minutes before the first race starts.  Avoid the lines; pick up early!  It's not a makes race day run smoother for everyone when you pick up your gear in advance.  That's why we give special raffle prizes and other cool stuff away to those who pick up early!!

If you can't make it to advanced packet pick up and have to miss out on the race we are unable to get you your packet. We try not to be wasteful; so all packets must be picked up on or before race day. Unfortunately we cannot hold it for you to pick up or mail it to you after the race. Any left over packets get recycled and/or donated immediately following the event.

If you can't run for any reason, please feel free to still pick up your packet at advanced packet pick up or on race day.

Military Discount
Yes!  Send us your rank and branch to and request a military discount code.  We'll send you a 10% off code that you use on all 3W events throughout the calendar year in which it is requested. (Does not apply to 'packaged or bundled' races or virtual events.)  You'll also receive special use instructions in the email at that time! Note: may be required to show proof at time of packet pick up! 

Groups/Team Of 5 Or More
When you have a group of five or more, everyone saves $5! The way this works is as follows:
-Participant 1: Signs up first at full price and creates a TEAM. You will have to create a team name and a password so that only your group can sign up with you. (Click here for info on how to create a team.)-Participants 2 through 4: Register like normal making sure to join the team, at full price.
-Participant 5 and on: Signs up, joining the team as well, and notices their registration is $5 cheaper! WOO HOO! 
Then, a $5 refund is automatically applied to participants 1 through 4 (assuming they paid at least $5.00 for the race)!

Cool, huh? Teams must be created or joined at time of registration. Team Rewards/Refunds will not be awarded retroactively. I.E: you must sign up for a team at registration to be eligible for the $5 discount or refund.

My coupon code/voucher isn't working, what do I do?
Thanks for your patience, this is an easy fix. First, DO NOT complete your registration. Please email us the voucher/coupon code, a little info on where you got it, and if applicable, a picture of the voucher/gift certificate. We'll get back to you shortly and look into why the code may not be working! If you're on a time crunch because of a price increase, don't worry, we'll honor it when we fix your code. 

Your well behaved, leashed dog and well behaved, belted in child in a stroller are welcome at the Longmont 5K event.  Please start in the appropriate wave with other dogs or strollers at the BACK of the pack to start. You do not need to register a child riding in a stroller.

Are Headphones Allowed?
Yes, you may run with headphones. We just ask that you leave one ear bud out or have the volume low enough to hear important announcements at the start/finish and volunteer/course marshal directions on the course!

​Can my child run with me? Do I have to register them/pay for them?
​Of course your kiddo can participate! 

If your child stays in the stroller the whole race, no, you do NOT have to register them as a separate participant. 

Our rule is, if they are using their own two feet to participate in one of our races, then, YES, you do need to register them. This is due to safety, participant counts for city permits and calculation of materials needed for the race!

Top finishers are scored based on GUN TIME.  Age group finishers are scored based on CHIP TIME.

The shirt is the same style, cut and logo design for both distances.  Each 5k AND Half Marathon finisher will receive a FINISHER'S MEDAL at the finish line.  You must finish the race to receive the finisher's medal.

On race day, you may visit the 3W Races Registration table/tent in the expo to exchange shirt sizes or purchase additional shirts while supplies last.

If your shirt size is not listed on the registration page, then we have sold out of that size.  Please select the 'no shirt' option for a $5 discount.  It is possible that some racers will not pick up their packets and you may be able to get a shirt in your size on race day after the race.  Check with the 3W Races table in the expo!

Learn more about the courses on the Course Information Page!

Race registration fees are non-refundable.  If you already registered and will not be racing with us on race day, you are still welcome to pick up your packet (shirt, bib, goody bag) during advanced packet pick up.
Transferring from distance to distance on the same race day can be done through the registration site directly for no additional fee other than the difference in pricing, if any, as long as spots are still available in the distance you wish to run.  Log in to and click on the appropriate 'Transfer' tab at the top of the page. You can also transfer to another runner through that link.

If you want to transfer your registration to a different DATE of a 3W owned event, you can also do this through your RunSignUp account for a $15 fee. We will allow this when requested at least 72 hours BEFORE the start of the event.  Run Sign Up will take what you paid, less the $15, and apply to another 3W Races Event date in the same calendar year that you select.

The race will not be postponed or cancelled due to weather unless something SEVERE is happening such as lightning storm, tornado or white-out conditions.  If that is the case, announcements will be made on our Facebook page and on the race webpage in addition to racer email communication.  99.9% of the time, the race will go on as scheduled.
