Hangang Cross Swimming 2026 Cancellation | Free Han River Swim?

2026 Hangang Cross Swimming Competition! This event’s famous for getting postponed or canceled year after year whenever it rains, and it’s been through all kinds of setbacks. This time too, rain was in the forecast a week in advance, so I kept watching and wondering whether it would actually go ahead…

Finally, on race day at 6:30 AM on June 20, this text message came through.

“Are you hesitating to leave because of the rain? The event will be held.”

After seeing that message, I packed a raincoat and headed to Jamsil. Then came the surprise: at 9:30 AM, we were notified on-site that the event was canceled.

😤 Dealing With a Sudden Cancellation at 9:41 AM

The Han River event venue under pouring rain, with people left wondering where to go.

The scheduled start time was 9:00 AM, but even after that passed, nobody was allowed into the water. We just kept waiting until around 9:20 AM. Hundreds of people stood in the rain asking when we’d be able to start.

I noticed group shirts with names of regional cities printed on them, which made it clear that quite a few participants had taken early-morning KTX trains from outside Seoul.

Chaos broke out.

Something felt off, and sure enough, the event was officially stopped at 9:41 AM.

I understand that cancellation itself couldn’t be helped. When I woke up that morning, I checked the CCTV footage and immediately thought, “There’s no way this is happening today.”

Looking at that current, I’d honestly want to stop anyone from getting into the water. When water gets released through the submerged weir, strong currents can create whirlpools. No matter how good a swimmer is, there are situations where getting back to the surface becomes extremely difficult.

The decision itself was the right one. The problem was announcing at 6:30 AM that the event was going ahead, then reversing that decision at 9:40 AM. With rain falling all night, it was reasonable to expect increased water discharge. If a postponement or cancellation notice had been announced earlier, a lot of people could’ve avoided wasting both time and money.

💸 Facing a No-Refund Policy With Souvenirs Instead

The organizers’ position was that refunds wouldn’t be issued. They pointed to a clause in the event guidelines stating that if severe weather made the event impossible to run, participants would receive commemorative items and the event would be concluded.

The souvenirs I eventually picked up after all the confusion.

The towel color looked a bit dull, but the otter design was actually pretty cute. Still, as compensation for 64,000 KRW… it felt a little lacking.

I wasn’t the only one who felt that way. Within two days, more than 600 refund request posts appeared in the Songpa-gu Swimming Federation cafe. One participant who traveled from another region said they lost around 250,000 KRW after adding accommodation and transportation costs.

I’ve also heard that around 500 participants gathered in a KakaoTalk open chat room and started preparing legal action.

What’s striking is that this wasn’t the first time. During Typhoon Hinnamnor in 2022, the Seoul city government reportedly requested that the event be halted the day before, but the federation pushed ahead anyway. Refunds weren’t provided then either, and a lawsuit followed. The court ultimately ruled that the organizers had to pay back part of the entry fee as well as legal costs.

The participant who personally filed that lawsuit back then is apparently helping this year’s participants learn how to prepare legal documents. At this point, it almost felt like a recurring pattern.

🏊 Diving Into Free Han River Swimming Instead

Now that I’ve vented enough, here’s the practical side of things. If you’ve been dying to swim in the Han River, this part’s for you.

You can swim in the Han River even when there’s no event. And it’s free!

It’s the exact same water as the 64,000 KRW competition. On race day, you pay 64,000 KRW. On an ordinary day, it’s free.

The Han River is actually a popular open-water swimming spot. If you visit Jamsil Hangang Park on a weekend morning, you’ll often spot colorful safety buoys floating around.

I first tried Han River swimming when I’d only been swimming for about a year and a half. I brought a GoPro, filmed my swim, crossed to the opposite side, enjoyed some snacks, and made plenty of great memories.

Han River swimming isn’t as difficult as it might seem. Here are some important tips.

👀 Checking CCTV Before Getting In

The first step before entering the Han River is checking the CCTV feed. Through TOPIS, Seoul’s traffic information system, you can view the live camera at the north side of Jamsil Bridge.

The camera mainly points toward the road, but you can still check the river’s current and the amount of water being released through the submerged weir.

Here’s how I judged conditions:

– Murky water and a fast current → Skip it

– Lots of white foam around bridge piers or the submerged weir → Skip it

– The day after rainfall or noticeably higher water levels → Skip it

If you can look at that screen and immediately conclude, “Not today,” you’ve already developed a decent sense for river conditions.

🎽 Swimming With a Safety Buoy Is Essential

A safety buoy is an inflatable float attached around your waist. I considered open-water swimming without one completely reckless. It’s essentially life-saving equipment.

It serves two major purposes.

First, when you get tired during a swim, you can grab the buoy, float for a while, catch your breath, and even use it like a kickboard.

Second, it helps rescue boats and passing vessels spot your location. That’s why they’re made in highly visible colors like neon pink, orange, and bright green.

Wetsuits and fins aren’t absolutely necessary, but they definitely make things easier. A wetsuit helps with water temperature and provides extra buoyancy, which becomes noticeable during longer swims.

If 2 km feels intimidating, fins can be a good option. Personally, I preferred swimming barefoot because walking in and out of the river while wearing fins wasn’t very easy.

⚠️ Staying Safe Around River Currents

The whirlpool effect I mentioned earlier is probably the biggest hazard in the Han River. When water is released through the submerged weir, the surface may appear calm, but powerful downward forces can develop underneath.

Even strong swimmers can struggle to return to the surface or escape if they’re caught in these currents. That’s why I think it’s best to skip swimming after heavy rain or on days with strong flow. There are plenty of other days to enjoy the river. The Han River is available throughout the season from June through September.

There’s another important difference from pool swimming: underwater visibility is extremely limited in open water.

Because navigation can be difficult, practicing head-up freestyle beforehand helps a lot. One useful landmark is the red brick building along the riverbank near the north side of Jamsil Bridge. Every time you briefly lift your head to sight forward, quickly locate the red building and keep adjusting your direction toward it.

For reference, the river crossing itself is about 800 meters. But once you drift with the current and make navigation adjustments, the actual swim usually ends up closer to 1,000 meters. A round trip works out to roughly 2 km.

That’s a solid workout, so pacing yourself properly is important.

💡 Who Should Come Here?

1. Swimmers frustrated by the same-day cancellation of the Hangang Cross Swimming event and looking for another outlet for that energy

2. Anyone interested in trying Han River open-water swimming for the first time but unsure where to begin

3. Swimmers who want to train and adapt to Han River conditions before entering a competition

💬 Wrapping Up With Final Thoughts

The Hangang Cross Swimming event definitely has its appeal. There’s something special about standing on the starting line with hundreds of people chasing the same goal and finishing with a medal around your neck.

What’s disappointing is that so much of that excitement depends on how the event is managed.

The Han River is always there, it’s free, and it doesn’t ask for 64,000 KRW. On days when conditions are right, heading out for regular training honestly seemed like the better approach.

I just hope the refund situation gets resolved properly.
