Also this weekend
Age-group distances at Weihai are, in the organiser's own words, still 'TBC' — nothing more specific has been published for any distance, including the 100km headline race itself. Worth flagging plainly: the wider 2027 Triathlon World Tour calendar (reported independently by Triathlon Magazine Canada, Slowtwitch and World Triathlon's own media release) lists Weihai's elite race on the T50 tier — Olympic/sprint-distance, draft-legal racing, the direct descendant of the old World Triathlon Championship Series — rather than on the 100km T100 tier. t100triathlon.com's own site nonetheless lists Weihai among its 2027 'Triathlon World Tour' priority-access venues without stating a distance. Until the organiser confirms one way or the other, don't assume the 100km T100 format is what age-groupers will actually race here.
Leg 1 of 3
Swim — 2km
Not described in any detail by the organiser beyond the city name — no beach, bay or course layout has been published for T100 racing here. Worth knowing as informed precedent, not confirmed fact: Weihai has hosted World Triathlon Championship Series and World Cup elite racing since 2008 at Halfmoon Bay, in the city's northeastern corner, a course the International Triathlon Union has praised as one of the most scenic on the calendar. The WTCS elite swim there has run as a 1,500m, two-lap course. None of that is confirmed as the T100 venue or distance — the 2km T100 distance shown here is the series' standard 100km-race swim leg, not a number published for Weihai specifically.
- Venue
- Coastal water off Weihai (exact venue not yet announced)
- Elevation gain
- No official figure published — see notes above
- Surface
- Sea — open water off the Yellow Sea coast.
Wetsuit: Not published. Applying the general T100/World Triathlon banding (mandatory below 15.9°C, prohibited above 24.6°C) against typical late-September Yellow Sea temperatures near Weihai (roughly 22-24°C early in the month, cooling toward 21-22°C by the 25th-26th), a wetsuit looks plausible but not certain — this is an inference from seasonal averages, not an organiser statement.
Leg 2 of 3
Bike — 80km
No route, elevation profile or road-closure detail has been published for T100 racing here. The 80km distance shown is the series' standard 100km-race bike leg, not a figure confirmed for Weihai.
- Venue
- Weihai, Shandong province (exact route not yet announced)

Where T100 Weihai starts and finishes
T100 Weihai starts at Weihai coastline, Shandong province (exact swim/transition venue not yet announced) and finishes at Coastal water off Weihai (exact venue not yet announced). We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on.
What you can qualify for
Not confirmed for Weihai. T100's 100km races generally serve as qualifiers for the Qatar T100 Age-Group World Championships, but that pathway has not been stated for this venue — and given the tier ambiguity above (Weihai's elite race sits on the T50 calendar, whose own finals are reported for Hamburg, not Qatar), it isn't yet clear which championship, if any, an age-group result at Weihai would feed into.

Race Day Info & Checklist
On the day
- This will be T100's first-ever race in China, and the organiser's own site currently offers nothing beyond a date and a priority-access sign-up — no athlete guide, course map or venue detail exists yet.
- Weihai itself is a genuinely experienced multisport host, not a first-timer for triathlon generally. It has run World Triathlon Championship Series and World Cup elite events since 2008 at Halfmoon Bay in the city's northeastern corner — the first Chinese city to host a full WTCS stop since the 2011 Series Final in Beijing — and the International Triathlon Union has called the course one of the most scenic on the circuit. That is real precedent for local road-closure and event experience, but it describes prior World Triathlon elite racing, not a confirmed T100 course.
- There's a genuine classification wrinkle worth knowing about, not just a formality: independent reporting on the 2027 Triathlon World Tour calendar (Triathlon Magazine Canada, Slowtwitch, and World Triathlon's own media release covering the new PTO/World Triathlon partnership) places Weihai's elite race on the T50 tier — Olympic/sprint-distance, draft-legal — rather than the 100km T100 tier. t100triathlon.com's own site still lists Weihai as a 2027 'Triathlon World Tour' venue with T100-style priority access sign-up. Whether age-groupers here end up racing the 100km T100 format, a shorter T50-style distance, or something else entirely has not been confirmed by the organiser either way.
- No athlete WhatsApp group or QR code has been published for this event. Worth a factual note for anyone planning around one: WhatsApp itself has been blocked in mainland China by the Great Firewall since 2017, and is normally only reachable there with a VPN installed before arrival — so even once/if an official group is published, don't assume it'll work the same way it does at other T100 venues without some advance planning.
- Weihai Dashuibo Airport (WEH) is the nearest airport, roughly 15km from the city, with limited international service concentrated on South Korea (Seoul), plus routes to Taipei, Tokyo, Singapore and Kuala Lumpur — most international travellers should expect to connect via a major domestic Chinese hub (Beijing, Qingdao or Shanghai) rather than flying in directly.
- China operates a visa-free transit policy of up to 240 hours (10 days) for passport holders of a substantial list of countries — including the US, UK, EU member states, Australia, Canada, Japan and New Zealand — through designated entry ports, and has separately simplified approval for foreign nationals attending sporting events. Requirements change and depend on nationality and exact entry point, so this is general context only — check current, event-specific guidance from the organiser or a Chinese consulate before travelling, rather than relying on this page.
Checklist
- A wetsuit, pending confirmation of the water-temperature call for a late-September Yellow Sea swim
- Passport valid well beyond the race dates, plus a check of current China visa/visa-free transit rules for your nationality
- A VPN installed before departure if you plan to rely on WhatsApp or other blocked apps while in mainland China
- Patience with logistics as a first-year T100 event — course maps, transition rules and cut-offs are all still to be published
- A close eye on the official site for updates, since this page will need real updating once more is announced
Transport, Spectating & Where to Stay
Transport

Frequently Asked Questions
When is T100 Weihai 2027?
25-26 September 2027 — a brand-new venue for the T100/Triathlon World Tour series, with no prior edition.
Where exactly in China is T100 Weihai held?
Weihai, a coastal city in Shandong province — though the organiser hasn't yet named the exact swim, bike, run or transition venue within the city.
What distances does T100 Weihai offer?
Not published — the organiser's own site describes age-group distances as 'TBC.' Don't assume the standard 100km T100 format applies until it's confirmed.
Is T100 Weihai actually a T100 race, or a T50 race?
Genuinely unclear as of research. t100triathlon.com lists Weihai among its 2027 Triathlon World Tour venues with T100-style priority access sign-up, but independent reporting on the wider 2027 calendar places Weihai's elite race on the T50 tier (Olympic/sprint-distance, draft-legal) rather than the 100km T100 tier. Treat this page as covering the venue the organiser has filed under 'T100,' not as confirmation of the eventual age-group distance.
Has Weihai hosted triathlons before?
Yes, extensively — Weihai has hosted World Triathlon Championship Series and World Cup elite racing since 2008 at Halfmoon Bay, and was the first Chinese city to host a full WTCS stop since the 2011 Series Final in Beijing. T100 itself is brand new to the city, but the city isn't new to hosting international triathlon.
Is there a published athlete WhatsApp group for T100 Weihai?
Not published for this event. It's also worth knowing that WhatsApp is blocked in mainland China and normally needs a VPN installed before arrival to use — plan accordingly regardless of whether an official group eventually appears.
Does T100 Weihai qualify for the Qatar T100 World Championship?
Not confirmed. T100's 100km races generally feed the Qatar qualification pathway, but Weihai's tier (T100 vs T50) is itself ambiguous in current reporting, so no qualification route has been stated for this venue specifically.
Do you need a visa to race T100 Weihai as a foreign athlete?
It depends on your nationality — China offers visa-free transit of up to 240 hours for passport holders of a substantial list of countries through designated ports, and has simplified approval for people attending sporting events, but exact requirements vary and should be confirmed directly with the organiser or a Chinese consulate closer to the date.
When were T100 Weihai results published?
Nothing to show yet: results only appear here after the 2027 edition is run. The official results source will also have them.
