On June 30th, 2024, I participated in a 100km marathon held at Lake Saroma in Hokkaido! As it is an official race where the Japanese record was set, the course is flat and easy to run on. However, on the day of the race, I will be battling against the scorching heat of the road with temperatures exceeding 30°C! I set my target time to be under 10, 9 hours and 30 minutes, and set off! ● Lake Saroma Ultra Marathon official website https://saromanblue.jp/ ● Running log data (Strava) / strava ● Items worn (excerpt) ・Cap https://www.feelcap.jp/ ・T-shirt https://www.gachio-ch.com/project-gi... ・Shorts https://a.r10.to/hgzKYW ・Socks https://a.r10.to/h5Mkor ・Shoes https://www.hoka.com/jp/cielo-x1/1147... ・Waist bag https://a.r10.to/hk9XXn ・Watch https://amzn.to/3L17krX ・Heart rate sensor https://amzn.to/3REOn1Y ・T8 neck cooler https://tomospit.com/collections/onli... ・I ingest https://a.r10.to/hkPv7k ・Aminosaurus https://a.r10.to/hUgtNl ・Salt gel https://amzn.to/3W8tm2l ・Katsusup https://www.staminasports.jp/ *Links include affiliate links ■Subscribe to the channel here: http://bit.ly/2LiaF6Q ■Instagram: / gachio_ch ■Threads: https://www.threads.net/@gachio_ch ■X (Twitter): / gachio_running ■note: https://note.com/gachio_running ■Strava: https://strava.app.link/Gachio ■Gachio website https://www.gachio-ch.com/ ■Gachio Radio now on air!
