Pro Team Housing

  • UCI teams and Domestic Elite Teams can take advantage of a special discounted room rate at the Hyatt Place Denver Tech Center Hotel, for only $129 per night. Includes free breakfast.
  • We only have a limited supply of these rooms which are on a first come, first served basis, and must be booked prior to July 5, 2024.
  • Reserve your rooms using this hotel link, by contacting the hotel’s central reservations department at 1-888-591-1234, or by calling the hotel at 303-804-0700. Attendees should identify themselves by the Group code G-TWIL and / or the Littleton Twilight Criterium to receive the group room rate.

  • We will do our best to offer host housing to travelling Pro Teams. If you are a Pro Team seeking Host Housing, please complete this form. All requests must be received by July 1, 2024. If you are willing to host racers from a pro team, read about Hosting a Visiting Racer [PDF] for more information.

Volunteering and Host Housing

  • Volunteers race for free but must register to volunteer before registering to race.
  • Please consider offering your home to members of a pro team. Many cannot attend our race if they can’t secure host housing. As anyone who has done this before will tell you, it is a very rewarding experience for both racers and host, and usually results in long term friendships. And of course, hosts race for free! Hosts must sign up by July 1. For more information on being a host, read Host a Visiting Racer [PDF].

Race Notes

  • Combined amateur race categories race together but are scored separately. Note that bib number colors and number sequence correlate to your category.
  • Neutral support (“pit”) is on course, just after the last corner (6), with medical just past it on S. Nevada Street (see Course Map).
  • Neutral support by ROL wheels will have a very limited supply of wheels. Though not required, if possible, please bring your spare wheels to neutral support before your race (wheels in, wheels out).
  • For safety reasons we may aggressively pull dropped riders. However, if you are pulled, it DOES NOT count as a DNF. That only happens if you quit or cannot continue racing.
  • If you are pulled, the best place to exit the course is W. Powers Avenue at S. Sycamore Street, one block past corner #1 on the inside of the course.
  • LAST LAP FOR EVERYONE: If you are in a combined race (where two or more race fields are racing together but are scored separately) please note that the last lap applies to all racers on course regardless of whether you have been lapped. When / if the leaders in the fastest group pass on their last lap, it is now your last lap. Check the lap counter each pass and when it says 1 lap to go, be on the lookout for this lead group. If you are passed on the finishing straight, best to start sprinting as soon as they pass! The judges will know how many laps you’ve done and will adjust the results accordingly.
  • SPECIAL NOTE FOR WOMENS P-1-2 RACE: This race starts near dusk (7:45 p.m.) and ends in complete darkness. Mobile lights around the course will be turned on before the start of this race; however, lighting for most of the course is supplied by streetlights which can only be turned on by their light sensors. Don’t worry — they will come on and the course will be adequately lighted throughout the race. Clear or transition lenses are recommended.
  •  Live Results will be available and accessible via the QR code on your “Special Notice” that will be attached to your bib number.
  • The pro races will be livestreamed and available on the ACC YouTube channel. Some amateur races will likely also be broadcast and if so will be available on Littleton’s YouTube channel. Please check back for details.
  • DCB Events, the folks that put on Colorado’s largest road race, the Boulder Roubaix, is organizing a race in Boulder on the Sunday after Littleton’s race. It will be added to the Bicycle Colorado calendar once it is finalized. Littleton Twilight Criterium racers will receive a discount code to the Boulder race upon completing your registration.
