Si no desea recibir una camiseta con su paquete de carrera, tenemos dos opciones para que los participantes donen sus camisetas oficiales de la carrera.

Dona tu camiseta a ayuda humanitaria.

A través de este programa, en 2020, pudimos donar más de 40,000 camisetas de carreras a Denver Rescue Mission y a Samaritan's Purse para Operation Christmas Child y para sus esfuerzos globales de ayuda humanitaria. En 2022 y 2023 pudimos asociarnos con estas organizaciones y continuaremos en la carrera 2026.

In 2024, we began donating shirts to the Veterans Community Project in Colorado.

Dona tu camiseta a la Carrera de la Base Militar BB.

Las primeras 29 olas (un tiempo de 10 km más rápido que 75:00) requieren una prueba de tiempo para que podamos ubicarlo exactamente en la ola correcta para su ritmo.

You can select any of the other waves without proof of finish time. This way you can participate with others like yourself and not get lost in a mass start. Learn more about how our waves work.

Las primeras 30 oleadas están reservadas para aquellos que esperan terminar antes de 75 minutos y tienen un tiempo de clasificación desde may 26, 2025. 

Así es como puedes calificar: 

1. Use your 2025 BOLDERBoulder time: Anything 1:15:00 or faster gets you in the perfect qualified wave for your pace. 

1. Use your 2025 ColderBOLDER 5K time: Anyone who finished faster than 37:30 minutes automatically gets in a qualified wave. Check your results. 

1. Use other races (since may 26, 2025) Use results from ANY timed race, from 5 kilometers to a marathon, which you’ve completed since may 26, 2025 and we’ll place you in a qualified wave based upon your time. Check the Equivalent Times Chart to see how your race time translates to a 10K time. Submit your result to qtimes@bolderboulder.com. 

We can help you start with your family or friends; the rest of the day is up to you. If you want to be in the same start wave, register everyone online at the same time. Enter the names of those you want to run with in the appropriate field.

Anyone submitting a qualifying time will be placed in the wave that they qualify for. If you want to run with friend or family in different waves, drop back into the latest wave of your group.

Si deseas cambiar de ola o correr en una ola calificada, podemos hacerlo realidad, suponiendo que todavía haya dorsales disponibles en la ola que deseas. El costo es $15.   

To request a bib number change prior to the race, email us at qtimes@bolderboulder.com – Note: you won’t be allowed to move up to a faster wave on race day unless you have the correct bib number for that wave. 

For all bib changes on Saturday or Sunday, bring us your original bib number and come to our SOLUTIONS tent at the Race Weekend Sports Exhibit on the Pearl Street Mall. The cost is $20. 

We will also accommodate Race Day bib changes for $20 – bring your original bib number and come to our SOLUTIONS TENT at the START AREA in the parking lot near 30th and Walnut beginning at 5:30 a.m. on Monday may 25th.
