Bib/Merchandise Pick-up Information

PLEASE NOTE there will be several changes to on-line and on site registration for this year to minimize in-person interactions on site.

ON-LINE REGISTRATION will END on September 22nd, 2021 at 11:59pm, AND we will NOT be processing any WALK UP or ON SITE REGISTRATIONS at this time. ON SITE PICK UP will ONLY be for cyclists to pick up bibs, helmet stickers, goodie bags and to purchase or pick up pre-ordered merchandise.

We will also be extending On Site Pick Up times this year to make it more convenient for people and to minimize waiting. We encourage you to pick up your bib/helmet sticker/goodie bag/pre-ordered merchandise prior to Ride Day at any one of the convenient times listed below.

  • Thursday, September 23rd: 1:00pm – 8:00pm
  • Friday, September 24th: 1:00pm – 8:00pm
  • RIDE DAY: Beginning at 5:30am  (Please arrive at least 30 minutes prior to your departure window time to ensure timely ride start.)

*As always, we will have printed maps available on site, but encourage you to download or print the maps from the website to be more environmental. Bib pins and map copies will be relocated to a self-serve station away from registration, so that cyclists can help themselves.

Departure Windows Times/Information

(Subject to Change for 2021)

Instead of cyclists starting all at once, we plan to implement “Two Departure Windows” to limit in-person interactions at the Start line. This means that cyclists may begin the Ride at any time during the designated departure time frame for your selected distance. This “staggered” approach allows for greater natural social distancing throughout the day along the courses, at aid stations and at the Finish line.

100 & 85 Mile Routes | 6:45am-7:15am, last departure is 7:15am

50 Mile Route & 25 Mile Route | 7:25am-8:10am, last departure is 8:10am

Please start within the Departure Window of the distance you signed up for! Wave starts have been modified to departure windows in order to facilitate social distancing and to ensure no overcrowding on the course or aid stations. Everyone is anxious to start the ride so please play your part and maintain social distancing.

** Please pin your bib number on the back of your jersey (not the front) and place helmet sticker on the front of your helmet!

4:00pm – All Routes and Michelob Ultra Post Ride Street Party close. (While we will welcome riders after 4:00pm, we cannot guarantee food and beverage will be available after this time. This is a requirement of our permit with The Shops at Northfield.)

Ride Cutoff Times 2021

100 & 85 Mile Routes | 6:45am – 7:15am, last departure is 7:15am

50 & 25 Mile Routes | 7:25am – 8:10am, last departure is 8:10am

Individual Route Cutoffs:

  • All cyclists riding the 100/85 Mile Routes MUST be through Aid Station #1 by 8:10am. 100 mile riders must be at 19th & Jackson St. in Golden (mile 25) before 9:20am or they will be directed to the 85 mile route.
  • All cyclists riding the 50 Mile Route must be through Rest Stop #1 by 9:00am. After 9:30am there will be no Denver Police Department support.
  • ALL CYCLISTS must be through Rest Stop #1 by 9:30am.
  • After 9:30am ANYONE leaving the Aid Station #1 will be directed to ride the 25 mile route ONLY.

The routes and finish line area will close at 4:00pm.  No Exceptions.

Please note that when we close the route the following will happen:

  • Aid Stations will close and there will be no food or water on the route. Aid Stations have published open and close times, which will be provided at a later date. Services will not be available after these published times.
  • There will be no route support at all – SAG, Medical, or Mechanics
  • We cannot guarantee that there will be refreshments, etc. remaining at the Post Event Street Party

To complete the course before it closes please pay attention to the following:

  • Maintain an average speed of 11 mph (100 mile riders). Ride a shorter distance if you cannot maintain this average.
  • Do not spend too much time at Aid Stations: wear your masks, stop in for a brief break, but limit your break to no more than 10 minutes, if possible. Aid Station protocol will change based on government guidelines, please pay attention to signage and volunteers.
  • Be aware of the published cut-off times. These have been calculated to provide you with a guideline to complete the ride with full support.
  • Be aware of the time!

If you do not believe you will be able to complete the routes before the courses close, please stop your ride at an aid station prior to its published close. We ask that cyclists call a friend or family member for pick-up from the route. The Denver Century Ride SAG vehicles will be on the course, however they are not taxi’s, and due to social distancing requirements they will not return you to the Finish line as in year’s past.

In the case of inclement and dangerous weather, the route will be closed and we ask that you seek shelter.  If the Ride Director asks you to leave the route and get in a support vehicle, and you refuse to leave the course please know that you do so at your own risk.   We realize how important it is for everyone to complete the ride, however we encourage you to be safe.

Aid Stations

Aid stations will be stocked with water, Nuun (hydration mix), fruit, bagels, sandwiches, and nutrition products all served according to updated health guidelines.   Please note: not all items are available at all aid stations.  Portable toilets and hand washing stations will be available.  Hand sanitizer will be provided on or near the service tables. Please use frequently.

We try to have a gluten free options available at all aid stations but do encourage you to bring your own energy bars if you have severe food allergies as we cannot guarantee there will not be cross-contamination.   Please make sure you read the labels if you are concerned about what might be in the product.

Riders must wear bib numbers (supplied with registration) to obtain food and access to certain areas of the route.  Medical support will be available at all aid stations; however, medical personnel will not be dispensing comfort medications such as: Aspirin, Ibuprofen, Tylenol. Participants are asked to bring their own comfort medications as needed.

Due to COVID-19 we will not be allowing family/friends to join you at the Aid Stations. However, if you have arranged a pick up at an aid station, please let the entrance volunteer know that you are awaiting a pick up.

2021 Aid Station Locations/Mile Markers TBD:

(Locations or Markers May be Subject to Change)

Bike Mechanics

There will be Bike Mechanics at all Aid Stations. Please note: There will not be a bike mechanic at the Water Stops.   We are very thankful for the great support from the following bike shops:

PLEASE NOTE: The bike shops and mechanics are on site to help with basic repairs and supplies that are $10 or less.  The goal is to keep you on the ride and safe.  Should your bicycle need more expensive supplies please be prepared to compensate the mechanics for the supplies, including tires but not tubes.   We encourage you to make sure your bicycle is in good working order before heading out on the Denver Century Ride.

Please carry a tube for your tire with you. If you need a tire change refresher, contact one of our partner bike shops, they will be happy to teach you.

Route Splits 2021 TBD – Be Aware!

  • 100/85/50 from 25 Mile Route: the long distance routes will continue straight on 23rd Ave. while the 25 mile turns left on Clay St.
  • 100/85 Miles from 50 Mile Route: From 32nd Ave. the 85/100 continues straight. The 50 mile turns left at Pierce St.
  • 85/100 mile split – the 85 continues straight on Ford St., the 100 goes right on 19th St in Golden. Note: these two routes merge at Colfax Ave. and US 40.

Route Support & SAG Wagons

SAG wagons will rove each of the courses with water and road assistance to help riders experiencing mechanical trouble or those who become too fatigued to finish. Please be prepared to handle your own flats and minor repairs. SAGs will only provide assistance to the nearest aid station where you may wait for another SAG moving forward, or phone a friend or relative to pick you up. Due to social distancing we will limit the capacity of all SAG vehicles.

If you need route support:

  • Flag down one of the SAG (Support and Gear wagons) They are identified with signs on their cars that say “DCR Support” – If you are stopped at the side of the road and do not need help but see a support vehicle, please give them a thumbs up so they can continue on to help others on the route.
  • Call the dispatch number listed in the final rider instructions provided via email, on Facebook and on the website the week before the ride.
  • Stay where you are – if you move we will have a hard time finding you.

 Route Signage

  • There will be signs posted on the routes in the ground with arrows and directions.   They are yellow and have the Denver Century Ride Logo on it.  These are very important.  Please pay attention. Finally, we use spray chalk to highlight obstacles, etc. and supplement the lawn signs.

Rider Safety Rules

 The Denver Century Ride is a Rules of the Road bicycle ride. This means cyclists are required to obey all traffic laws per CO vehicular codes. The ride is conducted on open roads with vehicular traffic. Roads include both marked and unmarked hazards. Though we go to great lengths to make the ride as safe as possible, always remember that safety is in your hands and ride by these rules:

  • Wear a helmet at all times – NO EXCEPTIONS.
  • Carry ID and relevant medical information.
  • Rules of the road apply; same rights and duties as the driver of any other vehicle
  • Please only ride single file and maintain social distancing.
  • Ride in the right lane, except when passing another vehicle, preparing for a left turn or avoiding hazards. Never pass cars on the right unless they are stopped at a light or making a left turn.
  • Never ride against traffic
  • Never assume motorists see you or that you have the right-of-way.
  • Ride on paved shoulders and bike lanes when present and free of hazards.
  • Obey all traffic lights, signs,  regulations and law enforcement/emergency personnel.
  • Pass on the left only, announce “passing” or “hello” or “on your left”, when passing other cyclists.
  • When riding with others use hand signals to indicate road hazards, stopping, slowing, right, and left turns. If you are unsure of proper hand signals contact your local bike shop and go on a shop sponsored group ride.  They will be happy to help you.
  • Prepare properly – nutrition, hydration, training, and appropriate gear/clothing for sudden changes in weather conditions.
  • Wear appropriate gear to protect yourself: glasses, masks and gloves and always wear a helmet.
  • Respect others: riders, volunteers, host communities, motorists, pedestrians, law enforcement & the environment; do not litter. Keep your nutrition wrappers, etc. in your jersey pockets. Trash receptacles will be provided at every Aid Station.
  • Expect the unexpected; your first responsibility is to be safe.

Finally, be aware that cyclists are subject to the same tickets and fines as vehicle drivers. Law enforcement has the authority and the mandate to uphold traffic laws during this event – this includes traffic tickets for moving violations (i.e., failure to stop or yield and removal of riders from the course if necessary, for their safety or the safety of others.)
