Most Ironman events have a time limit of 16 or 17 hours to complete the race, course dependent, with the race typically starting at 7:00 am. The mandatory cutoff time to complete the swim is 2 hours 20 minutes. The mandatory bike cut off time for when an athlete must have completed their swim, transition and bike varies generally between 10 hours and 10 hours 30 minutes from when an athlete began their swim. The mandatory run cutoff varies between 16 and 17 hours from when athlete began their swim. Many races will also have intermediate bike, run, and transition cut off times specific to each race venue. Any participant who completes the triathlon within these time constraints is designated an Ironman.

The name "Ironman Triathlon" is also associated with the original Ironman triathlon that is now theIronman World Championship.Held inKailua-Kona,the world championship has been held annually inHawaiisince 1978 (with an additional race in 1982). Originally taking place in Oahu, the race moved to Kailua-Kona in 1981 and it continues today.[4]The Ironman World Championship has become known for its grueling length, harsh race conditions, andtelevision coverage.[5][6]

There are other races that are the same distance as an Ironman triathlon but are not produced, owned, or licensed by the WTC. They include The Challenge Family series'Challenge Roth[7]and theNorseman Triathlon.

The event series is owned by The Ironman Group, which is owned byAdvance Publications,following the acquisition from the Wanda Sports Group in August 2020.[8]

History

edit
Aloha Towerwas the original bike-to-run transition site

The idea for the original Ironman Triathlon arose during the awards ceremony for the 1977OʻahuPerimeter Relay.[9]Among the participants were representatives of both the Mid-Pacific Road Runners and the Waikiki Swim Club, whose members had long been debating which athletes were more fit, runners or swimmers. On this occasion,U.S. NavyCommander John Collins pointed out that a recent article inSports Illustratedmagazine had declared that Belgian cyclistEddy Merckxhad the highest recorded "oxygen uptake"of any athlete ever measured, so perhaps cyclists were more fit than anyone. Collins and his wife Judy Collins had taken part in the triathlons staged in 1974 and 1975 by the San Diego Track Club in and aroundMission Bay, California,as well as the 1975 Optimist Sports Fiesta Triathlon inCoronado, California.A number of the other military athletes in attendance were also familiar with the San Diego races, so they understood the concept when Collins suggested that the debate should be settled through a race combining the three existing long-distance competitions already on the island: theWaikikiRoughwater Swim (2.4 mi or 3.9 km), the Around-Oahu Bike Race (115 mi or 185 km; originally a two-day event) and theHonolulu Marathon(26.219 mi or 42.195 km).[10]

Until that time, no one present had ever done the bike race. Collins figured by shaving 3 miles (4.8 km) off the course and riding counter-clockwise around the island, the bike leg could start at the finish of the Waikiki Rough Water and end at theAloha Tower,the traditional start of the Honolulu Marathon. Prior to racing, each athlete received three sheets of paper listing a few rules and a course description. Handwritten on the last page was this exhortation: "Swim 2.4 miles! Bike 112 miles! Run 26.2 miles! Brag for the rest of your life",now a registered trademark.

With a nod to a local runner who was notorious for his demanding workouts, Collins said, "Whoever finishes first, we'll callhimthe Iron Man. "Each of the racers had their own support crew to supply water, food and encouragement during the event.[11]Of the fifteen men to start off in the early morning on February 18, 1978, twelve completed the race.Gordon Haller,a U.S. Navy Communications Specialist, was the first to earn the title Ironman by completing the course with a time of 11 hours, 46 minutes, 58 seconds. The runner-up John Dunbar, aU.S. Navy SEAL,led after the second transition and had a chance to win but ran out of water on the marathon course; his support crew resorted to giving him beer instead.[4][12][13]

With no further marketing efforts, the race gathered as many as 50 athletes in 1979. The race, however, was postponed a day because of bad weather conditions. Only fifteen competitors started off the race Sunday morning. San Diego'sTom Warrenwon in 11 hours, 15 minutes, 56 seconds.[10]Lyn Lemaire,a championship cyclist from Boston, placed sixth overall and became the first "Ironwoman". Lemaire[14]finished her race in 12 hours 55 minutes and 38 seconds, only 1 hour 39 minutes and 42 seconds slower than the winning time for the men's race. Collins planned on changing the race into a relay event to draw more participants, butSports Illustrated'sjournalist Barry McDermott, in the area to cover a golf tournament, discovered the race and wrote a ten-page account of it.[10][12]During the following year, hundreds of curious participants contacted Collins. In 1980 27-year old Dave Scott took the event by storm when he shattered the current record by close to 2 hours, completing the race in 9 hours and 24 minutes. For the 1981 event there were more than triple the entries, at 326.[15]

There have been 19 different ways to qualify for the Ironman. Some of the ways include being a Hawaii Resident who won an event drawing, attaining a win in your age group at a previous Ironman, or even having a "Human Interest Story." Such human interest stories include participants who are cancer survivors and war heroes injured in battle.[16]

Valerie Silk and WTC

edit

Around 1979 Collins no longer wanted to direct the Ironman race and approached Nautilus Fitness Center owners Hank Grundman and Valerie Silk about taking over control of the race. Grundman previously had extended his club's facilities to many of the Ironman competitors. Following the couple's divorce in 1981 Silk received ownership of Ironman.[17][18]That year she moved the competition to the less urbanizedHawaiʻi Island[10](called the Big Island) and in 1982 moved the race date from February to October; as a result of this change there were two Ironman Triathlon events in 1982.

A milestone in the marketing of the legend and history of the race happened in February 1982.Julie Moss,a college student competing to gather research for her exercise physiology thesis, moved toward the finish line in first place. As she neared the finish, severe fatigue and dehydration set in and she fell, just yards away from the finish line. AlthoughKathleen McCartneypassed her for the women's title, Moss nevertheless crawled to the finish line. Her performance was broadcast worldwide and created the Ironman mantra that just finishing is a victory. By the end of that year the race had maxed out at 1,000 participants, with a lottery used to fill the field while turning away another 1,000 interested participants.[18]

In 1990, with the help of Lew Friedland, Dr. James P. Gills acquired and purchased the Hawaii Triathlon Corporation, owner of the Ironman brand for $3 million from Silk. With the Ironman brand, Gills established theWorld Triathlon Corporationwith the intention of furthering the sport of triathlon and increasing prize money for triathletes.[19][20][21]

A number of non-WTC full distance triathlons have been held since the mid-1990s. The limited number of WTC-sanctioned events, and the limited number of entries available per race, have combined with a growth in the sport that has created demand for these non-trademarked events. Many of them share the 2.4-mile (3.9 km), 112-mile (180 km), 26.2-mile (42.2 km) format with the Ironman triathlon. Originally, many used the Ironman name. Due to aggressive trademark protection, most of these races no longer use the word "Ironman".

Today

edit

The Ironman format remains unchanged, and the Hawaiian Ironman is still regarded as an honored and prestigious triathlon event to win worldwide.[22][23]For the 2024 Ironman Triathlon, the men's race will be held in Kona, Hawaii in October and the women's race will be held in Nice, France in September.[24]

People completing such an event within the strict event time cutoffs are agreed to be recognized as "Ironmen"; the plural "Ironmans" refers to multiples of "Ironman" as a short form of "Ironman Triathlon." In the triathlon community an Ironman is someone who has completed a race of the appropriate distance, whether or not it falls under the aegis of WTC.

Swim Smart Initiative

edit

In 2013, Ironman piloted the "Swim Smart Initiative" in North America and brought with it some notable safety related changes to the Ironman format. These changes included new rules regarding swim course formats, water temperature regulations, pre-swim warm ups, wave starts, and additional rescue boats/watercraft (paddle-boards, kayaks, etc.). The Swim Smart Initiative also introduced "resting rafts" so that athletes may leave the water to rest without being disqualified.[25]Andrew Messick, CEO of the World Triathlon Corporation, wanted the Swim Smart Initiative to ease the stress of the open swim and allowing athletes to be confident in the swim. Removing the "mass start" and conducting a "roll start" has been one of the major changes the organization has made.[26]

Ironman World Championship

edit

Over time the popularity of the sport of triathlon grew, and the annual race on the Big Island became The Ironman World Championship. In 1983, admission to the race began following a qualification based system, whereby athletes had to obtain entry to the race by competing in another Ironman race and gaining a slot, allocated on a proportional basis. The Hawaii race consists of aswimin the bay ofKailua-Kona,abikeride across the Hawaiian lava desert toHāwīand back, and amarathonrun along the coast (fromKeauhoutoKeahole Pointand back to Kailua-Kona); finishing on Aliʻi Drive. The most recent Ironman World Championship took place on October 6, 2022, and was won by Gustav Iden of Norway in 7:40:24 and Chelsea Sodaro of the United States in 8:33:46.[27][28]

The current Ironman Hawaii course record was set in 2022 by Gustav Iden (Norway), whose winning time was 7 hours 40 minutes 24 seconds.Daniela Ryf(Switzerland) set the women's course record in 2018 with a winning time of 8 hours 26 minutes 18 seconds.[27][28]

Amateur triathletes can qualify for the World Championship through placement in one of the other Ironman series of races. Entry into the race can also be obtained through various contests and promotions, or through the Ironman Foundation's charitable eBay auction.

Training studies

edit

Many studies have been conducted to enhance the performance of the athletes who are training for the Ironman Triathlons while others studied the effects training has on the body and mind. In one study done by Clifford B. Sowell and Wm. Stewart Mounts Jr., "men who are 65 years old are 44% slower than one who is 35...and women is 48%"[29]

Athlete injuries

edit
Injuries or just sheer exhaustion can occur during the intense triathlon.

Triathletes train year round, and no matter how cautious, injuries are always possible. Many factors can be accounted for injuries happening, intrinsic factors are based on the individual and extrinsic factors are environmentally influenced.[30]The most common injuries in the running event, are to the ankle and foot which result in a sprain, fracture, and muscle strain. Knee injuries like patella tendinopathy. Lower back injuries such as intervertebral disc injury and myofascial pain. Cycling injuries are common in the knees, lower back, neck and shoulder. Swimming injuries happen most in the shoulders from the continuous rotations. This could happen when there is no form or control in swimming. The neck will see some minor injury when you are only breathing from one side. Thermal injuries will occur when the athlete is dehydrated, hypathermic, and hypothermic. It is important to stay alert and listen to your body when there is unfamiliar pain or fatigue.

Ironman series

edit

There are over three dozen Ironman Triathlon races throughout the world that enable qualification for the Ironman World Championships. Professional athletes qualify for the championship through a point ranking system, where points are earned based on their final placement in Ironman andIronman 70.3events. The top 50 male and top 35 female professionals in points qualify for the championship. Amateur athletes qualify for the championship by receiving slots allocated to each age group's top finishers in a qualifying event. The Ironman qualifying events include:[31]

Ironman world records

edit

The designation of "world record" is unofficial due to lack of course certification as well as World Triathlon Corporation not maintaining official world record status.[41]

Ironman 70.3

edit
Ironman 70.3 Budapest - 2014

In 2005, WTC instituted the Ironman 70.3 race series. This shorter course, also known as a Half Ironman, consists of a 1.2-mile (1.9 km) swim, 56-mile (90 km) bike ride, and 13.1-mile (21.1 km) run. As with the Ironman series, it consists of a number of qualifying races at various locations worldwide ending in a world championship race with athletes drawn largely from top finishers in the qualifying events.

For amateur athletes, some 70.3 events acted as qualifiers for the full Ironman World Championships in Hawaii.[52]However, the 2015 qualifying year marked a large de-emphasis on using certain Ironman 70.3 series races as a path for amateur athletes to qualify for the Ironman World Championships. The change was made to accommodate for the increased number of qualifying slots created from the full Ironman events which had been recently added.[53]

For professional triathletes, up to three 70.3 events can be used to accumulate points to be put towards their championship qualifying point rankings.[31]

Ownership and trademark

edit

Advance Publications,the parent company that owns WTC and subsequently the Ironman brand, paysroyaltiestoMarvel Entertainmentfor use of the Ironman brand.[54]As part of thelicensingagreement both Marvel and the former owner Wanda agreed to not use the "Iron Man" and "Ironman" trademarks in ways that would suggest an association with the other or cause brand confusion. World Triathlon Corporation CEO Andrew Messick has stated that the agreement has been in place for decades and the royalties paid are "not material to the business."[54]Iron Manfirst appeared in 1963, whereas the first Ironman triathlon was raced in 1978.

The Ironman Triathlon logo is a trademark of theWorld Triathlon Corporation.[55]The WTC has also registered the trademarks for "Ironman," "Ironman Triathlon," "M-Dot," and "70.3."[56]WTC has licensed the Ironman name for use, such as in the line ofTimex Ironmanwristwatches.
