Race Intelligence · Gurye, South Korea
Gurye sits beneath the Jirisan mountains, and that landscape deserves respect long before you reach the finish at the stadium. The 2026 full race is over, but its big lesson remains useful: give the bike hills their due and keep something for the run.

The course behind your race
The 2026 race began around Jirisan Lake Park and finished at Gurye Public Stadium. Its bike was described as hilly and the run as flatter, the reverse of an older course classification. Don't build a marathon plan around the wrong discipline. A new full-distance edition hasn't yet been confirmed.
Jirisan Lake Park, historic swim start
The 2026 federation names the Jirisan Lake Park venue. Follow the current buoys and keep the first long-course swim effort controlled.
Use clear sighting. Settle into sustainable effort.
Gurye full-distance bike, opening stage
The Korean federation describes a hilly bike; older race material calls it flat. Until the mapped gradients are reconciled, respect every rise rather than chasing early speed.
Cap climbing power. Begin fuelling early.
Gurye regional riding, early middle stage
A full-distance ride leaves no room for repeated efforts above plan. Continue fuelling and adjust speed to the road you actually meet.
Keep nutrition on schedule. Ride to effort, not speed.
Gurye cycling roads, later middle stage
The last cycling kilometres are for finishing the plan, not proving a disputed terrain profile. Keep energy available for the run.
Finish planned nutrition. Avoid a last hard push.
Gurye cycling return, final stage
The federation describes the 2026 run as flat, but older course metadata does not. Let the opening kilometres establish your real effort rather than assuming a particular gradient.
Find a repeatable stride. Check actual route changes.
Gurye marathon, opening stage
Use the river corridor's actual conditions and the aid stations to manage a full marathon, regardless of whether the course profile is flatter than older descriptions.
Stay on fuelling plan. Keep effort even.
Gurye marathon, later stage
This is not the stage to repay an over-ridden bike. Settle into the sustainable stride that remains and reassess at each aid station.
Hold steady effort. Take aid early enough.
Gurye Public Stadium, past finish area
Past event records put the finish near Gurye Public Stadium. The final kilometres reward measured decisions through the whole day, not an assumed hilly or flat course.
Commit only when sustainable. Follow the confirmed finish map.
This full race took place in October 2026. Confirm any new edition before treating it as upcoming, and obtain the current Jirisan swim, bike and stadium finish maps. The bike is described as hilly and the run as flat in the 2026 event information; the underlying course classification still needs correction before pacing is certified.

Prepare for Gurye
A finish range gives you something to work towards. The preparation is specific to this race: a long freshwater swim, restrained hilly bike and an unhurried marathon start are planned from confirmed terrain rather than a reversed course profile.
