Max PankratovA full triathlon season is a year-long project, and most of it happens far from race day. An athlete picks one race to build around, usually a fall full-distance event or a World Championship slot, then works backward: a qualifying 70.3, a long base block, a winter of volume. None of that planning works without fixed dates.
This IRONMAN calendar gives you those dates. It covers the rest of the 2026 IRONMAN season and everything confirmed for the 2027 IRONMAN schedule so far, full-distance races, IRONMAN 70.3 races, and both World Championships. New IRONMAN races 2027 dates get added here as they’re confirmed, so this IRONMAN race calendar stays current as the season develops.
What is IRONMAN? A quick primer for triathlon lovers
IRONMAN is a specific race brand, within the broader sport of triathlon. Navy Commander John Collins and his wife Judy Collins founded the first IRONMAN triathlon in Hawaii in 1978, combining three existing local races, the 2.4-mile Waikiki Rough Water Swim among them, into one continuous full-distance triathlon: a 3.8km swim, a 180km bike ride, and a 26.2-mile marathon run, roughly a bike 112 miles and run 26.2 miles stretch after the swim leg.
The full-distance format is what most people picture when they hear the name. IRONMAN 70.3, meanwhile, is the half-distance version, built around the same three disciplines at roughly half the length. Between both formats, the series now runs close to 150 races a year across more than 50 countries, making it the global premier brand in long-distance triathlon and a genuine hub for endurance sport worldwide.
IRONMAN events attract both professional athletes chasing Pro Series points and amateur athletes racing purely for their own IRONMAN journey, age group by age group, on the exact same bike course and run course as the professionals. The brand, once operated under the World Triathlon Corporation name, now runs under IRONMAN Group. Even so, the race format itself hasn’t changed since 1978: whoever finishes first wins, and everyone else is racing the clock and the distance.
How do you read IRONMAN PRO series schedule?
Every date in this calendar comes from official IRONMAN sources. Still, races get rescheduled, added, or pulled with little warning, and this page updates on a slower cycle than IRONMAN’s own. So if anything here ever disagrees with ironman.com/races, trust the official site first.
Big changes for 2026–2027 global premier you need to know
A few structural changes affect season planning more than any single race date does. Worth understanding these before you look at the tables below.
IRONMAN World Championship 2026 and 2027: single-day Kona format returns
From 2023 through 2025, the men’s and women’s full-distance World Championships ran on separate days, alternating between Kona and Nice. That split-venue era is over, and the world championship returns to its original single-day, single-venue format. Starting in 2026, both genders race the same day at the Kailua-Kona World Championship again, confirmed for October 10, 2026, with the IRONMAN World Championship 2027 date already locked in for October 9, 2027. Allowing athletes from both genders to race together on one course, along the coast of Hawaii’s Big Island, restores the format that attracts athletes from around the world to Kona in the first place, and it’s part of what keeps attracting athletes and drawing ironman competitors back to the race year after year.
IRONMAN 70.3 World Championship: Nice in 2026, Chattanooga in 2027
The IRONMAN 70.3 World Championship stays in Nice, France for 2026 (September 12 to 13), then moves to Chattanooga, Tennessee for August 28 to 29, 2027. This move is part of a new five-year Chattanooga agreement that also brings an IRONMAN Pro Series event back to the city.
However, one nuance is worth flagging for anyone chasing that 2027 slot: the qualifying cycle opened earlier than the venue announcement suggests. In fact, select international IRONMAN 70.3 races started awarding 2027 Chattanooga qualifying slots as early as July 5, 2026, a full year ahead of the World Championship itself.
IRONMAN 70.3 race calendar
The IRONMAN 70.3 calendar, sometimes searched as the half IRONMAN 2026 schedule or half IRONMAN 2027 schedule, covers the half-distance format (1.9km swim, 90km bike, 21.1km run), the most heavily raced format in the series, with 119 races on the IRONMAN 70.3 2026 schedule worldwide. Anyone tracking the IRONMAN 70.3 world championship 2027 slot count will want the qualifying section below too. The tables below cover the confirmed World Championship and the marquee North American build and qualifier races most commonly used to prepare for a full-distance season; for the complete IRONMAN 70.3 schedule 2026, check the official IRONMAN 70.3 race list directly, since a table this size changes too often to reproduce in full here.
IRONMAN 70.3: key races through the rest of 2026
The World Championship anchors this stretch, with two North American qualifiers from earlier in the season included for reference:
| Date | Location | Swim | Bike | Run |
| Sept 12–13, 2026 | Nice, France (IRONMAN 70.3 World Championship) | Ocean | See ironman.com | See ironman.com |
| Jun 21, 2026 (already raced, listed for season reference) | Mont-Tremblant, Quebec, Canada | See ironman.com | See ironman.com | See ironman.com |
| Jun 21, 2026 (already raced, listed for season reference) | Coeur d’Alene, Idaho, United States | See ironman.com | See ironman.com | See ironman.com |
IRONMAN 70.3: 2027 races confirmed so far
Only two races carry confirmed 2027 dates at the time of this update:
| Date | Location | Swim | Bike | Run |
| Aug 28–29, 2027 | Chattanooga, Tennessee, United States (IRONMAN 70.3 World Championship) | River | See ironman.com | See ironman.com |
| Apr 3, 2027 | Oceanside, California, United States | Ocean | See ironman.com | See ironman.com |
IRONMAN 70.3 Oceanside is traditionally the West Coast season opener. Its 2026 edition already ran on March 28, so the April 3, 2027 date is the one worth building a season around if Oceanside is your target.
Course profile data (swim, bike, run type) isn’t published for every 70.3 race in the sources available at the time of writing, marked above where that’s the case. Confirm exact course profiles on each race’s own IRONMAN page before building race-specific training around them.
IRONMAN full-distance race calendar
Full-distance IRONMAN, the original 140.6-mile format, sits at the top of the series. In total, around 43 full-distance IRONMAN races run in 2026 across the globe, making this the featured event of the whole calendar for most age group athletes.
Full-distance races already raced in 2026, for season context
If you’re mapping out how a full IRONMAN calendar year unfolds, these are the full-distance IRONMAN races that already ran earlier in 2026, before this update’s September starting point: IRONMAN New Zealand (Taupō, March 7), IRONMAN Texas (The Woodlands, April 18), IRONMAN South Africa (Nelson Mandela Bay, April 19), IRONMAN Lanzarote (Spain, May 23), IRONMAN Brazil (Florianópolis, May 31), IRONMAN Frankfurt (June 28, the IRONMAN European Championship), IRONMAN Cairns (Australia, June 14), and IRONMAN Chattanooga (Tennessee, September 27, technically still ahead of this update but close).
This same season also included two IRONMAN races on the same June 14 date, Cairns and Kärnten-Klagenfurt, a reminder that among the many IRONMAN races in 2026, the global calendar regularly runs races in parallel across different continents. Later in the year, IRONMAN Gurye Korea, IRONMAN Calella-Barcelona, IRONMAN Malaysia, and IRONMAN Maryland round out the full distance side of the calendar, each detailed in the remaining-2026 table below.
IRONMAN: remaining 2026 races

Course profiles for these later-season 2026 races weren’t published in the sources available at the time of writing, marked above where that’s the case, confirm directly on each race’s IRONMAN page.
IRONMAN: 2027 races confirmed so far
Only the World Championship carries a confirmed 2027 date so far:
| Date | Location |
| Oct 9, 2027 | Kailua-Kona, Hawaii, United States (IRONMAN World Championship) |
The 2027 North American full-distance calendar is largely unannounced as of this update, IRONMAN typically releases it in the fall. A handful of confirmed 2026 international fulls matter if you travel for races regularly, since recurring events like these often hold similar slots year over year, though that’s never guaranteed until IRONMAN confirms it:
| Date | Location |
| Jun 7, 2026 | Hamburg, Germany |
| Jun 28, 2026 | Frankfurt, Germany (IRONMAN European Championship) |
| Nov 22, 2026 | Cozumel, Mexico |
Yesim tip: if you’re spectating rather than racing, these later 2026 and confirmed 2027 dates are also worth locking in flights and hotels for early, especially for Kona and Nice, where race-week accommodation fills up months ahead.
Discontinued triathlon races: don’t build a season around these
This is the section that matters most this year for the wider triathlon community. After all, among the many IRONMAN races 2026 and other endurance events runners track, three triathlon events that anchored thousands of season plans no longer exist, and any race schedule built around them needs rethinking:
- IRONMAN Arizona (Tempe): the November 16, 2025 race was the final edition after 21 years, ended by course-permitting conflicts tied to Tempe’s ongoing development. IRONMAN is reportedly considering Lake Havasu City as a new home, but nothing is confirmed or scheduled as of this update.
- IRONMAN 70.3 St. George: this iconic course held its final race in 2025, and its North American Championship designation went with it.
- IRONMAN Mont-Tremblant (full 140.6): discontinued after 2023, with no full-distance edition run since 2024. Only the 70.3 and 5150 formats remain at Tremblant.
If any of these sit on an athlete’s goal board, that conversation needs to happen now, not in October when the season is already locked in. Race organizers and technical partners supporting these venues have shifted resources elsewhere, so waiting for a surprise revival isn’t a realistic plan.
IRONMAN Pro Series: how the elite season works
The Pro Series works as a points system professional athletes earn, not a separate race, by racing selected IRONMAN and IRONMAN 70.3 events across the season, March through October, building toward both World Championships. This is the IRONMAN pro series schedule that determines end-of-season rankings and prize money, closing out each year at the Experience Oman IRONMAN Pro Series finale in Muscat every December. Similarly, the 2027 Experience Oman IRONMAN Pro event will close out that season the same way. Even so, ranking, prize money, and qualification paths through the Oman IRONMAN Pro Series schedule apply only to professional triathletes; age-group athletes race the exact same courses in a completely separate overall competition, with no crossover in prize eligibility.
Beyond the Pro Series, the wider IRONMAN 70.3 series also includes well-known North American stops like IRONMAN 70.3 Augusta and IRONMAN 70.3 Waco among its many qualifying races. That said, exact 2026 and 2027 dates for both weren’t confirmed in the sources available for this update, so check ironman.com directly for their current status. Meanwhile, every full official rules document and each race’s own athlete guide cover race conditions, start line procedures, and drafting rules in more depth than a calendar page can.
How to use this calendar to plan your season
Season planning works backward from one fixed point:
- First, pick your A-race, usually a fall full-distance event or a World Championship slot.
- Then work back 8 to 12 weeks to a qualifying or build IRONMAN 70.3 race.
- Before that, place a long base training block.
- Finally, build winter volume before the base block even starts.
For the rules and logistics side of race prep, the official IRONMAN competition rules and each race’s athlete guide are worth reading well before race week. Both are published directly on ironman.com.
Which eSIM do you need for these countries?
A calendar spanning this many countries means connectivity is worth planning too, for the athlete and especially for anyone flying out to support them. After all, staying online for tracking apps, race updates, and everyday logistics abroad is easier sorted before you fly than scrambled together at an unfamiliar airport. Check Yesim’s eSIM plans for the country you’re heading to, wherever the season takes you.
Conclusion
The core of this calendar is simple: the rest of 2026 and everything confirmed for 2027 in one place, with a clear status on each date. Since IRONMAN adds and confirms new 2027 races throughout the rest of the year, this page will keep updating. It’s worth a check back as your own season plan takes shape.
