Cheyenne Frontier Days(TM) is an outdoor rodeo and western celebration in the United States, held annually since 1897 in Cheyenne, Wyoming. It bills itself as the "World's Largest Outdoor Rodeo and Western Celebration." The event, claimed to be one of the largest of its kind in the world, draws nearly 200,000 annually. Lodging fills up quickly during the peak tourist season throughout southern and eastern Wyoming, into northern Colorado and western Nebraska. The celebration is held during the ten days centered about the last full week of July. In 2008, Cheyenne Frontier Days was inducted into the ProRodeo Hall of Fame.
The rodeo draws visitors from different parts of the United States as well as internationally. These visitors generally stay in hotels, motels, or in recreational vehicles. High temperatures around 81 °F (27 °C) and fair weather are normal for the time of year when this event is held; the elevation is approximately 6,150 feet (1,870 m) above sea level.
Cowboy style bars and country and western themed establishments scattered throughout the city of Cheyenne are popular with many rodeo fans and participants, and they file in in large numbers after the night shows.
Prior to the annual kickoff of Cheyenne Frontier Days on a Friday, the annual walking of the steers is held on the preceding Sunday morning. This event, which attracts considerable attention, is based on the running of the bulls in Pamplona, Spain and in part inspired by the cattle drives of the Old West. In 2013, 447 steers, herded by mounted cowboys, walked three miles from Hynds Boulevard into Frontier Park. In 2015, 550 steers walked this route. It starts from a pasture north of the city and runs along Interstate 25, south and then through the city streets aforementioned into the park.
Cheyenne Frontier Days only has a full-time staff of five people year round. The rest of the work of running the myriad of events is done by volunteers, more than 2,500 of them every year. There is preparation before the event and cleanup after the event as well as all of the work that needs performed during the actual event.
In 2014, Cheyenne Frontier Days received the Professional Rodeo Cowboys Association (PRCA) Large Outdoor Rodeo of the Year award for the 16th total and 11th consecutive time. Frontier Days runs nine days with more sections of bull riding, saddle and bareback bronc riding than any other rodeo. The rodeo is also known for its large number of participants. All events are performed each day. The rodeo draws many of the sports top competitors due to its more than $1 million in cash and prizes available.
Frontier Days delivers three types of competition: roughstock events, timed events, and racing on the track. Roughstock events include bull riding, bareback bronc riding, saddle bronc riding, and rookie saddle bronc riding. Timed events include steer wrestling, team roping, tie-down roping, and women's barrel racing. Tie-down roping includes calf roping, steer roping, and senior steer roping. Some of the timed events are shown during slack.
Slack events are events that do not fit into the normal rodeo hours in the afternoon. Slack rodeo events are open to the public at no charge and usually take place in the early to mid morning hours. Slack events include calf roping, team roping, steer roping, barrel racing, and steer wrestling.
Cinch rodeo shootout is a one-day event composed of 40 competitors taking place in five events for one afternoon. At the end there is one winner. Competitors are professionals and college national champions. There is also a team format where the team represents a local business and winnings are donated to charity. Both the individual and team format is an elimination style contest. Participation is by invitation.
The five events are bareback bronc riding, barrel racing, bull riding, saddle bronc riding, and steer wrestling. The Cinch Rodeo does not take place every year as tour locations are determined annually and every rodeo does not make the list year.
Starting in 2019, the Professional Bull Riders (PBR) are hosting one of their four majors here, the Last Cowboy Standing event, which was formerly held at the Thomas & Mack Center in Las Vegas, Nevada. This move to the world's largest outdoor rodeo expands on a growing partnership. The event will be held for two evenings during Frontier Days. Last Cowboy Standing is one of the PBR's premier events, which means that the event will host the top bull riders and bulls in the PBR.
The Professional Bull Riders (PBR) had a Touring Pro Division event at Cheyenne Frontier Days for many years. It started in 2001 and ran through 2010. In 2011, the stand-alone bull riding event at Cheyenne Frontier Days became sanctioned by Championship Bull Riding (CBR), then from 2012 to 2018, it became the world finals event for said organization. As of 2019, the stand-alone bull riding event at Cheyenne Frontier Days is once again sanctioned by the PBR. 
Cheyenne Frontier Days features nightly concerts by popular music and comedy acts, a midway, a fair with rides, games, and food vendors, wild west shows featuring Western riding, an Indian village, and a large PRCA nationally sanctioned rodeo. A common moniker for the event is "The Daddy of 'em All®", based on its long history and the fact that the rodeo is billed as the largest such event in the world. The rodeo and the majority of the events are centered on the property of Frontier Park, but some of the events such as the pancake breakfasts are held in a different part of the city.
Three free pancake breakfasts are served each year which are sponsored by the local Kiwanis chapter. They are held every Monday, Wednesday, and Friday with close to 40,000 people taking advantage of this every year. The record for a daily breakfast is 39,111 people set in 1996. In one week, over 100,000 pancakes are served, along with over 3,000 pounds of ham. This event was started in 1952 by the Cheyenne Frontier Committee. The food is cooked on military ranges. The event takes place at the historic Cheyenne Depot Square.
On the days in between the free pancake breakfasts, the city of Cheyenne hosts the Grand Parade in the morning. The parade starts at the Wyoming State Capitol, goes down to the Cheyenne Depot Square, and then returns to the Wyoming State Capitol on an alternate street. Until 1925, with two exceptions, the Frontier Days parades were rowdy affairs. In 1926, upon request, Dazee Bristol created floats which are still in use today. The parade is now composed of floats, automobiles, horse-drawn antique carriages, riders in period dress, and top marching bands.
In 1898, shortly after the second Frontier Days occurred, the committee extended an invitation to Native American performers to participate in following Frontier Days. Since then, they have participated every year. One popular attraction is the Native American Village which is open throughout Frontier Days and is free. Historically, the visiting performers shifted their campground around until in the 1960s when the committee established a permanent campground, the "Indian Village." The Indian Village hosts authentic dancing, music, storytelling, and pow-wows. There are also exhibit booths and food vendors.
Behind the Chutes tours are free. There are 1–3 tours every day of Frontier Days. The tour follows the same path that the bucking broncs and bulls take from the pens behind the arena. The tour shows where the livestock is kept and rounded up. Then the tour follows where livestock go through gates to the chutes. Then it is out into the arena and the tour is finished by walking across the arena. Depending on what time the tour is taken, there might be livestock in the pens.
Authentic chuckwagon crews visit for a few days to demonstrate life on the Goodnight Trail, which was more than 100 years ago. Crews cook with standard ingredients; meals are judged and can also be tasted by the public. They are also judged on their wagon, tools, and campsite. The Championship Cookoff takes place on the last demonstration day. However, the champions do not get their buckles until the rodeo finals day.
The Old Frontier Town (previously Wild Horse Gulch) is open every day of Frontier Days. It is free and is located between the Old West Museum and the Indian Village. There are merchants, guest characters, and/or craftspeople and artisans in some buildings.
On the Frontier Park itself, not far from the stadium, there is the carnival midway, a fair with games, rides, and food vendors. The carnival runs the entire length of Frontier Days. There are a number of different options for daily and season passes.
This saloon is located on Frontier Park. The saloon is open from 11 a.m. until Midnight. This makes it available to anyone who is there for the rodeo and its events in the day. And then in the evening, there are nightly concert ticket giveaways, beer specials, bands, and the usual good time. It runs most nights of Frontier Days.
One day per year Frontier Days celebrates Fiesta Day. This is a day of Latino entertainment featuring folk dancers and other family events. Also included are concerts by famous Regional Mexican, Cumbia and Grupero music artists.
Another annual event is an air show featuring the United States Air Force Thunderbirds Air Demonstration Squadron, which takes place on Wednesday. The Thunderbirds made their public debut at Cheyenne Frontier Days in 1953 and have continued to perform regularly since then. The ground portion of this show along with static displays and flying of other aircraft takes place on the United States Air National Guard side of the Cheyenne Regional Airport. The Thunderbirds' main aerobatic display is performed over the campus at the Laramie County Community College.
Cheyenne Frontier Days Old West Museum is open all year round. There is a modest admission fee. It is located on Frontier Park. A statue of bull rider rodeo icon Lane Frost riding a bull stands near the entrance. There is an extensive exhibit of western carriages. There is also a permanent exhibit on the history of Cheyenne Frontier Days. During Frontier Days, there is also a Western Art Show and Sale in the museum. The museum also hosts the Cheyenne Frontier Days Hall of Fame for its rodeo. Inductees include legends such as Lane Frost, Chris LeDoux, Johnny Cash, Charlie Daniels, Reba McEntire, George Strait, and Garth Brooks.
Circa 1980, the annual Western Art Show has been taking place in the Cheyenne Frontier Days Old West Museum. To kick off the art show, a reception is held on the first day, which is usually also the opening day of Frontier Days. Top western and wildlife artists are featured using many different mediums. Those who register for the reception get many special benefits. First there is a buy-it-now option, which enables ticket holders to instantly purchase art at a premium. Then there is a live auction. Both of these enable ticket holders a chance to purchase art before it is made available to the general public. Tickets include art show admission, the Governor's Mansion reception, the official Western Art Show poster, the official show catalogue and a western dinner. After the special events are concluded, the general public is free to view and purchase art at the museum by paying the museum admission fee.
F.E. Warren Air Force Base and Cheyenne have a long history together. The U.S. Cavalry founded Fort D.A. Russell, the precursor to the base, in 1867, the same year Cheyenne was founded. For a few days during Frontier Days, the base conducts tours and specials. There are historic home tours, military reenactments, and tours of missile systems. There are also other specials, demonstrations, and transportation. The base is located on the outskirts of Western Cheyenne off Interstate 25.
Cowboy Church is held the first and last Sunday of Frontier Days. Services are held in the B Stand. Location is subject to change. Some services are held non-denominational and everyone is welcome to attend. Some services are held for the cowboys, such as Fellowship of Christian Cowboys.
One day during Frontier Days, the Wyoming National Guard may open its doors to the public. This event does not occur every year. The open house features equipment displays of the National Guard and of the F.E. Warren Air Force Base. Sometimes the U.S. Navy Parachute Team, "The Leap Frogs," performs at the event. There are shuttle buses from Frontier Mall to the event. Valid IDs are required. Security enforcement is in place at the base.
