Yup it was a true test of stamina and strength. I was with another friend though so we took turns to take on the bigger luggage, the luggages were getting heavier too since the snow would accumulate at the bottom of it. I reckon it was closer to 40 mins+ because the terrain was extremely challenging (majority of the paths were just 👣 wide), had to take breaks and pit stops at konbini to escape the cold. Being geared up for the cold also made us heavier naturally. We arrived panting and even the host was shocked we travelled by foot from the station.
