Omiš has now officially confirmed the 10th edition of the Omiš Half Marathon for 17 May 2026 at 9 AM, and this one matters beyond the local running calendar. The Omiš Tourist Board says all three main races, 5 km, 10 km, and 21.1 km, come with redesigned courses this year, while registrations are already tracking toward record participation.
That makes this a genuinely useful mid-May planning update for travelers, not just runners. If you want Omiš on an active spring weekend, this is a strong date to lock in early. If you were expecting a quiet shoulder-season Sunday in town, it is also a good moment to recheck where you are staying, how you are arriving, and whether you actually want to be in the middle of the race atmosphere or just nearby.
Before you go: the race starts at 9 AM on 17 May, late registration stays open until 7 May, and the official event page already links the route maps and registration details. If you are arriving that weekend, sort the practical parts now instead of assuming Omiš will run like an ordinary spring Sunday.
What is officially new this year
According to the Omiš Tourist Board, the biggest change is the route redesign across the whole event. The half marathon now enters the Cetina canyon only once instead of twice, with more of the course opening toward the coast. The 10 km race is described as faster and more fluid, while the 5 km route stays recreational but still runs along the sea, promenades, and the Cetina riverfront.

The official Omiš race page already shows the updated 21.1 km map, with separate visuals available there for the 10 km and 5 km routes too.
This is not a small wording tweak. It changes how runners should think about the course and how non-runners should think about the waterfront mood that weekend. The event page also confirms a children's race again this year, so the whole morning will read more like an active town festival than a niche sports slot.
Who can enter, and how long the easier pricing lasts
The half marathon and 10 km race are reserved for adult participants. The 5 km race is open to runners aged 12 and up with parental consent, while younger runners can join with additional approval and a medical certificate. Late registration is open until 7 May, after which last-minute pricing applies.
Race | Who it suits | Late registration until 7 May | Last-minute price after 7 May |
|---|---|---|---|
21.1 km | Adult runners targeting the full Omiš event experience | 45 EUR | 55 EUR |
10 km | Adult runners who want a faster coastal race | 35 EUR | 45 EUR |
5 km | Recreational runners, age 12+ with consent | 30 EUR | 35 EUR |
There is also an official 20% group discount for clubs or groups of ten or more runners. If that is your setup, the Tourist Board article points you to the event contact and payment instructions on the linked registration page.
What this means for travelers staying in Omiš
If you are coming specifically for the race, the practical message is simple. Book now, not the week of the event. Omiš is small enough that a high-participation race changes the feel of the place fast, especially around the seafront, the river edge, and the old-town core. The upside is obvious: a much livelier spring weekend than usual. The downside is also obvious: less room for lazy last-minute planning.
If you are not running but still want Omiš that weekend, you do not need to avoid the town. You just need to choose your rhythm honestly. Stay close if you want the atmosphere, the finish-line energy, and an active Sunday feel. Stay a little more detached from the center if you mainly want sea views and a slower pace. Our Omiš destination page is the better companion if you are still deciding whether the town fits your trip in the first place.
What to recheck before race weekend
The most important links are already live. Use the official Omiš Tourist Board article for the current event summary, then use the registration and race info page linked from it for categories, fees, and signup steps.
If you are driving in from Split, Makarska, or elsewhere on the coast that morning, keep an eye on HAK road conditions before you set off. That is not because this article is about a road disruption. It is because race-morning timing becomes brittle when you stack event arrival, coastal driving, and parking improvisation on top of each other.
This is the kind of spring event update AdriaEscape likes: official, timely, and clear on the traveler payoff. Omiš is giving mid-May visitors a stronger reason to choose the town, but only if they plan like the event is real, because it is.
