Race Day Weather

Average Temperature7.6°C / 46°F
Humidity77%
Peak Wind26 km/h
Rain Chance35%
Typical ConditionsThe organiser publishes hourly race-day readings for 10 past editions: the 9:00 AM start has ranged from 4.7C (2018) to 17.0C (2016), a 12.3C spread, with a median of 8.4C. The temperature rose an average of 5.2C during the race window, and 2 of those 10 starts were in rain.

What to Prepare: Do not pack for the idea of February in Japan. Start-line readings span 12.3C across the 10 published editions, and the air warms an average of 5.2C while you are out there. A long-sleeve with a throwaway top layer covers most years; decide gloves and a hat from the forecast, not the calendar.

Wind Impact on Race Day

Winds peaking around 26 km/h — the typical daily maximum for this date — can affect your pace by 5-15 seconds per kilometer in exposed stretches. Headwinds slow you down exponentially: a 20 km/h wind costs more than twice a 10 km/h wind.

Course Profile

Course TypePoint-to-point road marathon
TerrainRoad
ProfileTwo real climbs, not one. The Urado Bridge just past 20 km rises about 43 m over roughly 800 m to the course high point of about 49 m on the official chart (the 50 m figure quoted online is the bridge's height above the sea, not its climb). Then from about 41 km a ramp of some 600 m, which Japanese runners call the Haruno hill, lifts you about 31 m over the final 1.5 km into GIKEN Stadium at 33.4 m. Two bridge humps of around 16 m flank the Niyodo river mouth.

Course Analysis

The 2027 race, and how a runner abroad actually enters

The 13th Kochi Ryoma Marathon starts at 9:00 AM on Sunday, February 21, 2027 and closes the course at 4:00 PM, rain or shine. Entry is first-come, first-served for 10,000 places, from 12:00 JST on August 1, 2026 to October 31, 2026. The fee is 13,000 yen including accident insurance, with an optional 500 yen charity add-on. You must be 18 or older on race day, and the official outline covers both federation-registered and unregistered runners, so no membership is needed. There is no wheelchair division in the full marathon, though the 1.4 km fun run runs a separate wheelchair lane.

Here is the part English-language previews rarely answer: you can enter from abroad, and the place costs the same. The 2026 edition sold entries through Run Japan (English, simplified and traditional Chinese) and JTB Sports Station (English and traditional Chinese), both at the same 13,000 yen face price as the domestic channel — there is no foreigner surcharge. JTB's published handling fee for running events priced over 4,000 yen is 5.5%, roughly 715 yen, and its entry is limited to residents overseas (Japanese nationals included) and foreign nationals living in Japan. The 2027 entry page was still marked as in preparation in late July 2026, so check which channels go live on August 1.

Do not read first-come as a scramble. At the original deadline for the 2025 edition the race had taken only 9,513 of 10,000 places, and the organiser extended entry by 15 days, closing at 10,555. The 2026 edition was the first recent year to fill every category with no extension, at 11,327. Entries have grown 21.6% in two years, from 9,315 to 11,327, so the window is genuinely tightening — but the 10,000 figure behaves as a soft cap, and both recent editions finished above it.

The cutoffs bite hardest at 17 km, before the big bridge

The start is in front of the Kochi prefectural government offices; the official English page gives the landmark as in front of Kencho-mae Station of the city tram. You pass Harimaya Bridge, take the Nangoku bypass out of the city and turn for the coast.

Eleven timed checkpoints control the race. The first, at 5.02 km closing at 10:00, allows a very soft 11:57 per km — and then it tightens fast. The leg from 8.5 km to 13.2 km demands 8:31 per km, the quickest single segment anywhere on the course. The hardest cumulative demand is the 17.0 km checkpoint at 11:45, which needs a 9:42 per km average from the gun, a full 15 seconds per km faster than the 9:57 implied by the 7-hour limit.

That ordering is the thing to plan around, because of what comes next. The course high point, the Urado Bridge, arrives just past 20 km: about 43 m of climbing over roughly 800 m, topping out near 49 m on the official elevation chart. This 1,480 m bridge carries a 6.5 m roadway and footpaths just 0.75 m wide behind fences over 3 m tall. One number to discount when you see it repeated: 50 m is the bridge deck's height above the sea, not the climb. In short, the tightest cutoff pressure lands immediately before the biggest hill, so the buffer has to be built before the bridge, not on it.

Aid in this half (2026 edition) ran to banana and a local lactic drink at 9.8 km, yokan bean jelly at 11.8 km, and fish cake with cucumber at 15.1 km. Set the 17 km split with our pace calculator before you think about the bridge.

Katsurahama, the river mouth, and the hill at 41 km

Off the bridge the route passes Katsurahama, the beach where the statue of Sakamoto Ryoma looks out over the Pacific, then heads west over the Niyodo river mouth bridge to a turnaround at Niinoho-buchi in Tosa City. Two bridge humps of about 16 m sit either side of the river mouth, so the riverside is not the flat run-in that most course descriptions imply.

The checkpoints ease off here, with required segment paces slackening to between 10:16 and 10:32 per km. The course fills that gap with its second climb.

From about 41 km, a ramp of roughly 600 m — Japanese race reports call it the Haruno hill and treat it as the twin of the Urado Bridge, with the line that if Urado is the front of the course, Haruno is the back — lifts you about 31 m over the final 1.5 km into the Haruno sports park at 33.4 m. English-language previews of this race almost never mention it, which is exactly why it hurts: runners arrive braced for one climb and meet a second on empty legs. The finish is inside the stadium there, renamed GIKEN Stadium under a naming-rights deal running from January 2026 to March 2029; the official English page still calls it Haruno Athletic Recreation Park, and both names are current.

The late aid stations are where Kochi shows off. At 22.1 km comes chikukyu, a whole cucumber pushed through a tube of fish cake — elsewhere in Japan the two are simply sliced together, but stuffing the cucumber whole is the Kochi version, and Haruno is the prefecture's top cucumber-growing district. The same station serves aubergine jelly from Aki, which the organiser bills as Japan's top aubergine-producing area. Then Tosa somen noodles at 24.5 km, yuzu drinks from Umaji village at 29.4 km, and katsuo-meshi at 32.2 km, a rice ball seasoned with bonito-flavoured soy from a katsuobushi maker in Tosa City. At the finish the organisers serve straw-seared bonito, the dish the prefecture is known for. All 2026-edition details and subject to change.

The 7-hour limit is not really 7 hours

The official course map carries a line most previews skip: pass the final checkpoint and you receive a finisher certificate and medal even if you go over the 7-hour limit.

The arithmetic shows why that clause exists. The final checkpoint sits at 41.2 km and closes at 15:58, a cumulative 10:09 per km — 12 seconds per km more generous than the 9:57 that 7 hours implies. Clear it on the buzzer and you have 2 minutes left for the remaining 995 m. Practically everyone in that position finishes over 7 hours, so the rule reads as a deliberate decision to give those runners the medal anyway. If the published 7 hours had put you off this race, that is the number to reconsider.

Two cautions. The limit is gun time, taken from the start signal, so anything lost in a rear corral comes straight out of your buffer. And special drinks are not accepted, so you race on course aid.

For kit, plan for a rise rather than a number. Across the organiser's 10 published race-day records the 9:00 AM reading has ranged from 4.7C to 17.0C with a median of 8.4C, and the air warmed by an average of 5.2C during the race window, 8.3C in the sharpest year. A long-sleeve plus a throwaway layer covers most years, and our what to wear by temperature guide turns the forecast into a kit list. In the organiser's published finish-rate table of 11 editions, only 2016 fell below 91%, at 85.4% — and that edition also had the warmest start on record, 17.0C at the gun and 20.7C by 11:00.

Frequently Asked Questions

Can I enter the Kochi Ryoma Marathon from outside Japan, and does it cost more?

Yes, and no — you pay the same. For the 2026 edition two official overseas channels sold the race: Run Japan in English, simplified and traditional Chinese, and JTB Sports Station in English and traditional Chinese. Both listed the same 13,000 yen entry as the Japanese channel, so there is no foreigner surcharge.

JTB's published handling fee for running events over 4,000 yen is 5.5%, about 715 yen on this entry, and its channel is restricted to residents overseas (Japanese nationals included) and foreign nationals living in Japan. Entry for 2027 opens August 1, 2026 at 12:00 JST and runs to October 31; the entry page was still in preparation in late July 2026, so confirm which channels go live on the day.

Is there a lottery, and will it sell out before I decide?

There is no lottery — it is first-come, first-served for 10,000 places over a three-month window, which is unusual for a Japanese race of this size. February 21 is a crowded date: Kyoto, Kitakyushu and Kumamoto Castle all run the same day, and all three are lotteries — drawing on October 5 (planned), October 16 and October 15 respectively.

The calendar ordering is the useful part. Every one of those results lands before Kochi's first-come deadline of October 31, so you can enter the lotteries, lose them, and still take a place here. That makes Kochi the natural fallback for a February 21 marathon — provided places remain, which in recent years they have.

Recent history argues against panic. At the original deadline for the 2025 edition only 9,513 of 10,000 places had gone, and the organiser extended entry by 15 days, closing at 10,555. The 2026 edition was the first recent year to fill without an extension, at 11,327. Entries are up 21.6% in two years, so 2027 could be the first to genuinely close early — but no recent edition has, and the 10,000 cap has behaved as a soft ceiling, with both recent years finishing above it. Booking in the first half of the window is sensible; camping on the refresh button at midnight is not. Our marathon registration and lottery calendar tracks the windows that open alongside it.

What is the time limit, and how strict are the cutoffs?

The published limit is 7 hours from the gun, which works out at 9:57 per km — but the practical limit is more generous. The official course map states that if you pass the final checkpoint you receive a finisher certificate and medal even beyond 7 hours, and that checkpoint is at 41.2 km closing at 15:58, a cumulative 10:09 per km.

The pressure is earlier than most runners expect. Of the 11 checkpoints, the hardest cumulative demand is at 17.0 km (11:45), needing 9:42 per km — 15 seconds per km quicker than the overall limit — and the sharpest single leg is 8.5 km to 13.2 km at 8:31 per km. The first checkpoint at 5.02 km allows a soft 11:57 per km, which flatters early progress. Because the clock is gun time, a slow corral start comes out of your margin.

Is the Kochi Ryoma Marathon course flat?

Mostly, with two climbs that both matter. The Urado Bridge just past 20 km rises about 43 m over roughly 800 m to the high point of about 49 m. Then, from around 41 km, the Haruno hill climbs about 31 m over the last 1.5 km, with the steep part lasting some 600 m, into the finish stadium at 33.4 m.

Japanese race reports treat the two as a pair, but English previews usually mention only the bridge — worth knowing when you plan the last 5 km. Two bridge humps of around 16 m also flank the Niyodo river mouth in the thirties. If you see the Urado Bridge described as a 50 m climb, that figure is the deck height above the sea, not the ascent.

What is the weather like in late February in Kochi?

More variable than the season suggests. The organiser publishes hourly readings for 10 past editions, and the 9:00 AM start has ranged from 4.7C (2018) to 17.0C (2016) — a 12.3C spread on the same fixture, with a median of 8.4C.

The second number to plan for is the rise: the air warmed by an average of 5.2C between the gun and the day's peak inside the race window, and by 8.3C in the sharpest year. Two of those 10 starts were in rain. Kochi sits on the Pacific side of Shikoku, and the Japan Meteorological Agency's 1991-2020 normals for February 21 are a 13.8C high and a 3.8C low, with rain on roughly a third of late-February days.

Is the Kochi Ryoma Marathon a Boston qualifier?

Yes. The course is certified by the Japan Association of Athletics Federations and measured to AIMS standards — the 2026 official English page states both, and the 2027 outline lists the course as federation-certified with World Athletics course certification.

That means an official chip time can be used toward a Boston qualifying application if you meet your age-group standard; check where you stand with our Boston qualifying calculator. Note that course measurement certification is a separate thing from a World Athletics label — this race does not carry a Gold, Silver or Bronze label, and none is claimed.

How do I get to the start, and where does the race finish?

The start is central and easy to reach on public transport, which the organiser requires — there is no parking at the start site. From Kochi Ryoma Airport, take the limousine bus toward Kochi Station Bus Terminal, get off at Kita-Harimayabashi and walk 3 minutes: about 35 minutes and 900 yen in cash, one way, as of July 2025. From JR Kochi Station, ride the tram to Harimayabashi, change to a Kagamigawabashi, Asakura or Ino service and get off at Kencho-mae, 3 minutes on foot.

This is a point-to-point race finishing well outside the city at GIKEN Stadium in Haruno, so the organiser transports your bag from the start to the finish (designated bag only, no valuables). If supporters drive, the 2026 edition ran free shuttles from the temporary car parks to the finish venue, roughly every 15 minutes between 10:30 and 17:30. Book accommodation near the start.

Do I need federation registration, and does the 40 mm shoe rule affect me?

No registration is needed. The 2027 outline opens the race to both federation-registered and unregistered runners; the only requirement is being 18 or older on race day and believing you can finish inside 7 hours.

The shoe rule is narrower than it looks. The outline says sole thickness is measured after the finish and a sole over 40 mm voids the record — but only for federation-registered athletes who run under 2:21 (men) or 2:56 (women). If that is not you, your usual racing shoes are fine and your time is unaffected.
