2026 Chuncheon Marathon D-1

Segments

1. 0–5 km · 09:29

   Gongjicheon Bridge → Samcheon junction → Songam Sports Town → 1st U-turn

   A gentle rise to Samcheon junction, then a short out-and-back toward the reservoir just before 4 km. Start 10–15 s/km slower than goal while the field is packed.

   +38 m −37 m · Grade max 4.8% · 4.0 1st U-turn (reservoir) 5.0 Water
2. 5–10 km · 09:57

   Songam Sports Town → First climb → Sinyeon Bridge (Uiam Dam)

   Just past 5 km comes the steepest climb: about 34 m over 600 m (5–6%). Shorten your stride over it, then relax down to Uiam Lake rather than racing the descent.

   +47 m −48 m · Grade max 7% · 5.8 First climb 10.0 Water
3. 10–15 km · 10:26

   Baksa-ro along the west side of Uiam Lake

   Almost flat with the lake on your right. Settle your breathing after the climb and tuck into a group running your pace.

   +20 m −22 m · Grade max 2.6% · 12.5 Sponge 15.0 Water
4. 15–20 km · 10:54

   Baksa-ro → Gangwon Animation High → West Chuncheon

   One short rise of about 300 m around 17 km. It is brief, so just hold your effort over it.

   +26 m −22 m · Grade max 5.4% · 17.5 Ani High climb 17.5 Sponge 20.0 Choco pie 20.0 Water
5. 20–25 km · 11:22

   Sinmae Bridge out-and-back → Halfway

   Around 20.5 km you run about 600 m onto Sinmae Bridge and turn back. You pass halfway right after, a good moment to check in and set your second-half plan.

   +18 m −14 m · Grade max 2.3% · 20.6 Sinmae Bridge U-turn 22.5 Sponge 25.0 Sports gel 25.0 Water
6. 25–30 km · 11:51

   Yeongseo-ro → Chuncheon Dam

   The crux: a gentle climb of about 30 m stretching over 3 km from 26 to 29 km. Run by effort, not pace, and take your fuel before the climb starts.

   +30 m −29 m · Grade max 3.9% · 27.5 Sponge 29.1 Chuncheon Dam climb 30.0 Banana 30.0 Water
7. 30–35 km · 12:19

   Sinbuk → Sindong junction

   A short rise at 31 km, then downhill and gentle rollers. From 32.5 km the road widens and feels endless, so keep your eyes on the runner just ahead, not the horizon.

   +18 m −23 m · Grade max 3.6% · 32.5 Sponge 35.0 Water
8. 35–40 km · 12:48

   Yeongseo-ro → Udu-dong → Soyang 2 Bridge

   Flat running and the crossing of Soyang 2 Bridge. Expect wind on the bridge, and focus on posture and arm swing as fatigue sets in.

   +9 m −8 m · 37.5 Sponge 40.0 Water
9. 40–42.195 km · 13:00

   Soyang 2 Bridge → Gongjicheon finish

   A long, wide straight that feels longer than it is. Spread what you have left and lift for the final kilometer.

• Food: choco pie at 20 km, sports gel at 25 km, banana at 30 km. Take the gel at 25 km, right before the dam climb.
