Makoto@市民ランナーRan in 2025 · Finish time 1:32:39
“This time, my mother and friends from my hometown cheered me on from the roadside.”

Still nursing heel pain from a 100-mile race, the runner chose to build the pace gradually rather than chase a time. Cheered on by family and friends on the rainy, familiar Lake Suwa course, they finished in 1:32:39.

“I was anxious, but somehow I finished!”

They were worried because they had not been able to train sufficiently after changing jobs, but finished the race. They mentioned a slower time than the previous year, optional participant merchandise, and the crowd support.

“I enjoyed running while taking in the scenery of Lake Suwa.”

The runner ran the Lake Suwa half marathon a clear, windless day in 2 hours, 6 minutes, and 51 seconds, their best time of the year. They held a steady pace of around 6 minutes per kilometer and said it was part of their build-up for next month's Mt. Fuji full marathon.

A half marathon course around Lake Suwa in Suwa, Nagano Prefecture (諏訪市・諏訪湖).

The course is flat, with just 6.5m of elevation change, and runners keep Lake Suwa on their left.

This is not a Japan Association of Athletics Federations-certified event.

The main venue is Suwako Event Hiroba (諏訪湖イベントひろば), the former site of the Toyo Valve Suwa factory.

The start is at 9 a.m. and the time limit is three hours.

For the 38th edition,

three sections of the course were changed: the Yokokawa River mouth–Yokokawabashi detour was replaced by a straight route across Hakuchobashi on the Yokokawa River;

the finish moved from inside the yacht harbour to the area near the Nisseki Byoin-mae traffic signal in front of Suwako Event Hiroba;

and the turnaround section from the Suwa and Miyakawa river mouths to Suwa Central Park was extended slightly.

There are five cut-off point on course.

More details

Getting to the start

Finish line is at Suwako Event Plaza in Suwa City. Parking is by advance first-come reservation.

Getting to the finish

Suwako Event Plaza (諏訪湖イベント広場)

Finish is in the same lakeside area as the start. Heavy congestion expected around Lake Suwa; organizers recommend carpooling or public transit over driving.

Start shuttle

Public transit or carpooling is strongly recommended over driving. Temporary parking lots near the main venue (Suwako Event Plaza, Suwa) are allotted first-come at entry, and capacity is much smaller this year because the venue changed; runners without an allotted spot are directed to paid coin parking and akippa lots around the venue.

READY TO RUN

From race morning to after the finish.

Your start time, fuel and bag drop.
Know them ahead and the run feels easier.

Bib, the timing chip and race information are sent together in early October;

there is no race-day registration.

Runners are assigned to blocks by self-reported expected finish time and start simultaneously.

Anyone who leaves the expected-time field blank or submits an unrealistic time starts from the final block.

Aid station will be installed at 6–7 locations on course.

If you miss the cut-off times at the five cut-off point, you must surrender your bib and,

following an official’s instructions, board the collection minibus or walk back to the finish along the pavement.

Bags may be checked only in the designated bag provided with the pre-race mailing;

other bags will not be accepted.

Runners are asked to keep changing-room use brief, and eating inside is prohibited.

Parking is allocated on a first-come, first-served basis during entry.

This year, the number of spaces is significantly lower than last year because the venue has changed.

Those who miss out on allocated parking are directed to city centre pay-and-display car parks and the paid parking-reservation site akippa.

The organisers recommend car-sharing or public transport.

Finisher certificate will be issued online to all finishers.

Times are local to Suwa. Check the latest official information before the race.
