The runner competed all the way to the finish with a runner friend in the 10 km starting at Hamanako Boat Race Stadium. After six years, the runner achieved the goal of running in the 36-minute range and was delighted to place fourth in the 50s age category.

At the Hamanako Marathon 10K, the runner dressed as Hello Kitty and kept a relaxed pace, mindful of the heat. Cheers from students and friends provided a boost while the runner enjoyed lakeside views and short climbs.

Lake Hamana Marathon is a local event in Kosai, Shizuoka Prefecture, where you run with views of Lake Hamana and the Enshu-nada Sea.

The lake and sea are the first scenery highlighted by the organisers in their introduction to the event.

The course incorporates the waterfront landscape and presents the city alongside Kosai’s local specialities.

The races take place on roads around Boat Race Hamana-ko.

Using the same waterfront area as its focus while varying the distance by event,

the race welcomes everyone from adults running longer distances to children running shorter ones.

The programme includes 10 km, 5 km, 3 km and a 1.5 km parent-and-child event.

Although “marathon” appears in the event name, the published programme consists of these relatively short distances.

In the parent-and-child division, an elementary-school child and a guardian run as a team.

Grandparents are also included among eligible guardians, allowing multiple generations to take part together.

The 3 km race is open from elementary-school age through adulthood,

while the 5 km race has divisions for middle-school students and participants in high school and above.

Combining a family run with age-group races gives the event its character as a local community sports event.

The event is organised by the Hamana-ko Marathon Executive Committee and the Kosai City Sports Association.

It connects a run with waterfront views to local community participation,

while the lake and sea forming the backdrop of course remain key elements used to describe the event even in the shorter races.

Field size
10km: 1,200 people 5km: 700 people 3km: 300 people 1.5km (parent-child group): 150 groups
Typical race-season temperature: around 17°C (62°F)
Short sleeves — hydrate for the warmth

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.

To reach the venue, walk from the north exit of JR Araimachi Station towards Boat Race Hamana-ko.

The official registration information says the walk takes about 10 minutes and recommends using public transport where possible.

Free parking for cars is also available.

Registration takes place in the Sun Hall inside Boat Race Hamana-ko.

Start line and finish are in front of the facility, so follow the registration route through Sun Hall before going directly from the station to the start area.

The start order differs by event, and registration closes earlier than the latest-starting event.

If you arrive based only on your own start time, you may miss the registration deadline.

Baggage storage is free, but capacity is limited and valuables are not accepted.

If you plan to check a bag, allow enough time to walk to the storage area after registration.

Shops are available at the venue, and drinks are provided for participants.

Medical staff are also on standby, so follow the instructions on site if you need assistance.

Because the start and finish are at the same location, you can collect your belongings after finishing and then walk back towards Araimachi Station.

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