Can I participate if I do not have my race bib on race morning or decide to join the race without officially completing the registration process?

What is packet pickup?
All registered participants receive a race bag (packet or goody bag) that includes their official race number, race information, and promotional product samples. Your race bag must be picked-up on Saturday, October 9, 2021 from 9am-6pm at our Race Expo in Boulder.
What do I need to bring to packet pickup?
As a registered participant you will receive a final race confirmation sent via email a few days prior to race day. Please bring a copy of this confirmation and a photo ID to the Race Expo to receive your race bag.
Can I pick up another participant’s race bag?
Although we stress that it is very important that every registered participant pick up their own bag, we do realize that in some cases it is not feasible. If a participant is not able to attend the Race Expo and pick up their own bag, they can designate a proxy to do so by presenting a copy of the runner’s photo ID or a copy of the runner’s confirmation email. Please understand that without one of these documents we will not be able to release the race packet to anyone other than the registered runner.
Race Shirt sizes are not guaranteed; please arrive early for best selection.
What if I didn’t get my email confirmation or want to confirm my race entry?
If you did not get your confirmation email and would like to confirm that you are registered for the race, please email firstname.lastname@example.org.
Can I transfer to another distance before Race Day?
Yes. Please email email@example.com 14 days prior to Race Day, and we can complete the transfer for you If it is less than 14 days before Race Day, then all event changes must be done in person at the Expo Change Booth. Please keep in mind if you are transferring from the half marathon to the full marathon you will be responsible for paying the additional cost. If you are transferring from the marathon to the half marathon we cannot offer any refunds or credits.
Do you have any course time limit rules?
The Boulderthon® is open to all participants of age who are able to finish the marathon in 6 hours, and the half marathon in 3 hours. Participants wishing to complete their event within that timeframe will need to maintain a 13:43 minute/mile or faster pace. There will be no early start for runners.
If you plan on participating at a 13:44 minute pace per mile or slower, please be aware that our permit dictates that the streets that comprise the marathon route are reopened to vehicular traffic at 1:30pm. On-course support (aid stations) will close at this time.
Participants still out on the race course after 2:30pm will be asked to move to the sidewalks or re-route. SAG wagons will patrol the route providing support to these participants.
We also suggest that walkers and slower participants consider carrying a hydration pack that accommodates water and snacks.
Will you have Pace Groups?
We will offer free pace groups for the marathon and half marathon.
The pacers will be at the Starting Line 20 minutes before the start of the race. They will wear prominent singlets and they'll be carrying signs that show the pace that their group plans to run. The times offered for each race will range from 1:30:00 to 2:30:00 in the Half Marathon and 3:00:00 to 5:00:00 for the Full Marathon.
How do you capture my finish time?
Your official race bib has a timing strip on the back, so do not remove this strip. Once you cross the start line your timing strip activates, and will not stop until you cross the finish line. In addition, we will have various timing mats on the course to capture your progress along the way. Athletes vying for prize money will be judged on gun time, while age group awards will be issued based upon tag (chip) time.
Do you allow participants to walk in the races?
Of course! We do ask that you adhere to the time limit rules.
Do you allow participants to use headphones, phones, iPods, etc.?
We do not have any restrictions on the use of headphones, phones, or iPods. We strongly discourage the use for safety reasons. If you make a decision to wear a music-playing device during the race, please keep it at a low level so you can hear special instructions from course officials or emergency vehicles.
I love to run with my dog, may I bring him or her to run with me?
We also love our pups, but for safety reasons pets are not allowed on the course at any time. In addition the City of Boulder prohibits pets from being on the Pearl Street Mall.
Can I bike, rollerblade, roller skate, skateboard, etc. on the course?
No, we do not allow any “wheels” on the race course for safety reasons, other than approved wheelchair participants, emergency personnel or race officials . The use of “wheels” will result in a disqualification.
I’m a disabled athlete. Can I participate?
Yes, we will make every effort to provide a safe race experience for athletes of all abilities. If you are a disabled athlete and would like to compete, please email firstname.lastname@example.org to ensure we can accommodate any special requirements.
Can I run or walk with a baby jogger or stroller?
No, we do not allow baby joggers or strollers on course.
Do you offer Gear Check?
Gear Check is available Sunday October 10, 2021, only. Please do not bring gear to our Packet Pickup on Saturday. Due to security reasons we cannot accept gear bags prior to Race Day morning. You may bring your bag to the Start line and our event staff will transport it to the Finish/Expo area for your arrival. Participants may only re-use the “Clear” plastic bag they received at the Expo. Simply tear off the Gear Check tag from your race bib and affix it with the small tie provided to you at the Expo. Your official race bib number is also your gear check number. We discourage you from placing valuables in the gear check bags. For security reasons we will not accept backpacks, luggage or any large bags. All personal items must be placed in a clear bag, where contents are visible. No exceptions.
Please do not leave your bag unattended outside the official bag drop area. Bags left unattended may be confiscated due to Homeland Security requirements.
Please claim your gear as soon as possible after you complete the race. At 3:00pm any unclaimed gear will be transferred to the Stronger Faster Boulder office located inside Whole Sol (1420 Pearl Street, Boulder).
Items not claimed in one week will be donated to charity.
Will I receive a goodie bag?
Of course! What race is complete without one? Runners will receive a Boulderthon® reusable goodie bag pre-packed with refueling food and water after they cross the finish line.
