If you want an early-2027 hybrid race in the US, ATHX now has three before mid-March — San Diego 23 Jan, Las Vegas 6 Feb, Denver 13 Mar — and all three show an 'Enter now' button rather than a placeholder. What I could not confirm is the USD entry price for any of them, so check the fee on the event page yourself before committing.
ATHX’s 2027 calendar now lists seven events in the United States, and the first three are on sale: San Diego on 23 January, Las Vegas on 6 February and Denver on 13 March. All three carry an “Enter now” button on the organiser’s own events page, the same treatment as the 2026 US races that are already selling — not a “more info coming soon” holding line.
One thing this article does not give you is a price. I could not open the individual event pages for San Diego, Las Vegas or Denver on 11 October 2026, so there is no organiser-sourced USD entry fee for those three races here. A third-party retailer blog publishes figures for two of them; those are not the organiser’s numbers and I am not repeating them. More on that below.
The seven US stops on the 2027 calendar
Taken from the ATHX events page as it rendered on 11 October 2026:
| Event | Date | Venue |
|---|---|---|
| ATHX San Diego 2027 | 23 Jan 2027 | San Diego Convention Center |
| ATHX Las Vegas 2027 | 6 Feb 2027 | Expo at World Market Center Las Vegas |
| ATHX Denver 2027 | 13 Mar 2027 | National Western Complex |
| ATHX Miami 2027 | 12 Jun 2027 | Miami Beach Convention Center |
| ATHX Nashville 2027 | 14 Aug 2027 | The Fairgrounds Nashville |
| ATHX New York 2027 | 28 Aug 2027 | Javits Convention Center |
| ATHX Chicago 2027 | 11 Sep 2027 | Donald E. Stephens / Rosemont Convention Center |
The date and venue pairings for San Diego, Las Vegas and Denver also appear in the listing on the ATHX homepage, which is where I cross-checked them.
That is a clustered opening: three races in seven weeks across the south-west and Colorado, then a four-month gap before Miami in June. If you are in the western US, the January-to-March block is the part of the calendar that matters.
Registration status, with one caveat
On 11 October 2026, each of San Diego, Las Vegas and Denver displayed both “More Info” and “Enter now” on the events page. No waitlist wording appeared against any of the three.
The caveat is worth stating because the page is not uniform: “More info coming soon” does appear elsewhere on the same listing — I saw it adjacent to ATHX Berlin 2027 in one rendering. Button states on a live calendar change, and the listing renders in segments. Treat the above as a snapshot of 11 October 2026 and confirm on the page before you plan a trip around it.
A “Founders” label also sits in the listing near several 2027 entries, including the US dates. Its meaning is not explained in the page text I could read, and the listing order makes it ambiguous which event each badge attaches to, so I am not going to characterise it as a pricing tier or an early-bird rate. If it matters to you, open the individual event page.
The whole 2027 calendar, as far as I could count it
The homepage banner reads “2027 Calendar now live – our biggest season yet”, above a heading reading “2027 UK, EU & US events now live”. That US wording looks recent: a cached variant of the same page, reached with a tracking parameter, still showed the older “2027 UK & EU events now live”. I am noting that as an observation, not quoting the cached version as current.
Counting the 2027 entries visible on the events page on 11 October 2026 gave me 30 events across 13 countries — the UK, US, France, Spain, Italy, Belgium, Switzerland, Germany, Austria, Ireland, Portugal, Denmark and the Netherlands. Because the page renders in segments, treat 30 as a floor rather than a final total, and my own count rather than an organiser statement.
For context on how the season has grown, ATHX’s official equipment partner BLK BOX published that the 2027 season “spans 21+ cities worldwide” with tickets for 16 cities live at launch. That is partner marketing rather than the organiser’s calendar, and the content I could read was undated — but a launch figure of 21+ against a current count of around 30 is at least consistent with the calendar having expanded since.
I had intended to report precisely which of these stops were absent from the schedule announced in May 2026. I could not retrieve the article that documented that earlier schedule, so I am not making the “these weren’t there before” claim. What I can report is what the organiser’s page shows today.
Milan and Montpellier now have live pages
Two European additions are worth flagging because they came with full event pages and published fees. ATHX Milan 2027 runs at Fiera Milano on 6–7 March 2027, listed at €150.00 Individual Entry and €275.00 Pairs Entry. ATHX Montpellier 2027 is at the Montpellier Exhibition Centre and Sud de France Arena on 28–29 May 2027, at the same €150.00 / €275.00. Both checked 11 October 2026.
Those two pages sit in a different ID block from the main 2027 batch, which is circumstantial evidence they were added later — not something ATHX states.
What ATHX has charged, and what that does and does not tell you
Since I cannot give you a 2027 US price, here is the surrounding evidence, all read from ATHX’s own event pages on 11 October 2026. None of it is the San Diego, Las Vegas or Denver fee.
| Event | Individual | Pairs |
|---|---|---|
| ATHX Miami 2026 (10 Oct 2026) | US$149.00 | US$269.00 |
| ATHX Los Angeles 2026 (7 Nov 2026) | US$149.00 | — |
| ATHX Milan 2027 | €150.00 | €275.00 |
| ATHX London 2027 (23–24 Jan 2027) | £125.00 | £225.00 |
| ATHX St Gallen 2027 (10 Apr 2027) | CHF 135.00 | — |
| ATHX Copenhagen 2027 (31 Jul–1 Aug 2027) | DKK 1,120.00 | — |
All figures are the organiser’s listed prices on its event pages, checked 11 October 2026, each in the currency the page quotes. I have not applied a conversion because I did not source an exchange rate on the day, and entry prices on these pages may move with tier.
I also wanted to set a US ATHX entry against a US HYROX and a US DEKA entry for the same January-to-March window. I could not reach either organiser’s registration pages for that window, and without a confirmed ATHX US 2027 figure there is no left-hand side to the comparison anyway. So there is no head-to-head here. If you want the format differences rather than the fees, we have written up HYROX vs DEKA separately.
Format and divisions
ATHX describes its race on the homepage as a 2.5-hour continuous fitness competition across six zones: Warm-Up (30 minutes), Strength (20), Refuel (10), Endurance (30), Recovery (30) and MetCon X (30). That is the organiser’s own description of the format. We have a fuller walk-through in ATHX Games explained.
On divisions, every ATHX event page I read lists three categories — ATHX Lite, ATHX and ATHX Pro — with type Individual and Pairs, pairings Male, Female and Mixed, and heats running 08:00–18:00. That includes the 2026 US pages for Miami, Houston and Los Angeles, which match the 2027 European pages field for field. So ATHX’s US events have so far run the same three categories and two formats as its European ones.
I am deliberately not stating the 2027 US division list as confirmed, because those three event pages would not open for me. And across every page I did read — Bilbao, Madrid, Vienna, Paris, Valencia, Milan, Marseille, Amsterdam, Frankfurt, Brussels, St Gallen, Copenhagen and the 2026 US dates — ATHX lists only Individual and Pairs. No team division and no scaled division appears anywhere; ATHX Lite is the entry-level category. Absence from a page is weaker evidence than an organiser saying so, which is why that sentence is phrased the way it is.
What to check before you enter
Three things, all on the individual event page rather than the calendar listing: the current entry tier and price, whether the “Enter now” button is still live for your date, and what the “Founders” label means if it appears on your event. ATHX’s own events page is the only source worth using for any of them.
