The phrase 'Japan's Third Trail Running Boom' has been appearing more and more frequently. Media coverage paints a bright picture: lotteries with four-times oversubscription for popular races, international brands opening flagship stores one after another, young mountain runners featured in fashion magazines. And yet, long-running local races are quietly folding, volunteers are nowhere to be found, and aging organizers have no one to pass the torch to.

It's been a while, this is Tsutsumi from GO ASIA TRAIL, and on April 11, 2025, I participated in the Explore Your Backyard, a local trail running race held in Tucheng District, New Taipei City, Taiwan. I actually ran this race eight years ago in April 2017.

Following last year's race, I ran the Akiyoshidai Karst Trail Run again this year. Last year's race was my first time visiting and running in Akiyoshidai, and I wanted to go back again this year because of the spectacular view unique to the karst plateau and the great view from "Ryugo Peak" at the end of the race.

In this day and age when thick-soled, carbon shoes are the mainstream, I prefer barefoot shoes that go against the current trend. This is partly because thick-soled, soft-cushioned shoes do not suit my feet, but I have been running in barefoot shoes for more than 10 years. This includes the period from January 2020 to January 2023,

This is a continuation of the following article I wrote last time. Although the last review was about running Taiwan Sandals for trail running on the road, this time I would like to summarize my impressions when I ran in the mountains.

If you are a trail runner in Japan, you may have once wondered why there is no by UTMB race in Japan. The following races in Asia near Japan have already been designated as by UTMB (as of March 2023).

Prior to the coronavirus, entry to any marathon was by lottery, and it was not always possible to run. However, when the new coronavirus raged around the world in 2020, marathons around the world were either cancelled or drastically scaled back (for elite runners only), and I suspect that the opportunities to run a marathon were greatly reduced for the next three years.

Taiwan Sandal was introduced in October 2021. The following article is still popular on this site. It is currently the most accessed article on this site, and is ranked second in Google's search rankings, which is thought to be the reason for the large influx of visitors to this site.

The following Yahoo article inspired me to describe this article. The main character of this article, Yuri Suzuki, calls himself an "overseas marathon collector," so I guess I am like an "Asian trail version" of him.

When it comes to runners and trail runners, I believe that a GPS watch is one of the indispensable items. My first GPS watch was a Garmin Forerunner series. After that, I used the Suunto Ambit, EPSON's Wristable GPS for Trek, and for the past 3-4 years, I have been using a GPS watch made by Amazfit, a Chinese smartwatch brand, because of its cost-effectiveness.

The long new coronavirus, which began in December 2019, closed the road to overseas travel for three years. After a long period of endurance, the ban on inbound travel to Japan will be lifted in the fall of 2022, and Taiwan will resume accepting tourists from October 13, 2022, as if to coincide with the ban (some restrictions apply; notification will be made in late September 2022).

In this issue, we discuss the running sandals that are currently popular in the Taiwanese running community.

Twenty-one people were killed in the trail running race "Huanghe shilin baigongli yue yao yao sai" held in Gansu Province, China, from May 22 to 23. According to reports, there were abnormal weather conditions such as hail, freezing rain, and strong winds at high elevations (20-30 km).

It has already been a year since I last visited Taiwan. For the past year or two, it was normal for me to travel to Taiwan three or four times a year, but due to the new coronavirus, I have been practically unable to travel there. I am experiencing Taiwan loss or some sort of withdrawal symptoms, so recently I often hang out with Taiwanese people living in Japan and visit Taiwanese restaurants.

I started using Freeletics during the Golden Week holidays in May of this year. At that time, I was in the middle of a declared state of emergency. The gym I was going to was temporarily closed until the end of May, and the Corona police were working online/offline, so it was not an atmosphere where I could casually run outside. I wondered if there was a way to get a hard workout in at home, and I ended up with Freeletics.

It has been a while, but I am doing well. To be honest, the new coronavirus has left me with nothing to write about. Races in Asia have been postponed or cancelled across the board, and although there are plans for autumn and winter, there have been decisions here and there to cancel full marathons in Japan...so even if I do make it to the races, I am not sure if I will be able to travel to Japan.

A notice to all of you. I am pleased to announce that I have been appointed as an ambassador for the French sports brand DECATHLON.

Continuing from the previous article, regarding the Formosa Trail that I recently participated in. This article is about the race day on December 1. The Formosa Trail is the last race of the year for me.

I participated in the Formosa Trail (English: Formosa Trail; Chinese: 福尔摩沙古道), a trail running race held in Puli, Taiwan, for three days from November 30 to December 2, 2018. The Formosa Trail has five categories: 104 km, 65 km, 40 km, 16 km, and 8 km, and I entered and participated in the 40 km race.

I ran TransJeju, a trail running race held in Jeju Island, South Korea last week, October 20-21, 2018. Although I DNF'd at the 73.5km mark due to a knee injury, I would like to report on what I heard from other runners.
