ATHLETE VOICE

Shingo Inoue🇯🇵Ultra Runner

I took KatsuoStamina during 4 days of 330km training from Tokyo to Fukushima.It was a strenuous experience for me, but I was able to run at an average pace of 5 minutes and 30 seconds per kilometre -- the fastest I had ever run during my preparation period. I didn't have any noticeable muscle pain the day after I finished the total 330km. It convinced me of the benefits of KatsuoStamina.

For the IAU 24 Hour Asia-Oceania Championships, I chose KatsuoStamina.I took KatsuoStamina with miso soup after my digestive system failed in the second half of the race, and I think the fact that I kept taking Katsuo Stamina and converted the lactic acid into energy was the key to the last 30 minutes of the race.

Kaori Niwa🇯🇵Trail Runner

I won the first round of the 2017 Ultimate Tsaigu Trail Kuocang (UTGK) 100km race in a stunning upset! For this 100 km race, I took two bags of KatsuoStamina before the start of the race. During the race, I took two bags every 20 km.

This time I arrived at the 30km mark an hour ahead of schedule. This was unexpected: During the first half of the race, I had been allowing my heart to run at a faster pace than I had planned; I also had a leg problem for two weeks before the race. I wasn't able to run at my best, and I was worried about my muscles holding up to the end.

Usually in the second half of a long race, my body can't process lactic acid into energy any longer, and it builds up gradually, causing muscle soreness in my legs and hips. Strangely enough, that didn't happen at all this time.

I took two bags of KatsuoStamina at the 80km aid and was off. There, I passed the woman in second place. That meant there was one more to go, yet I felt like I was so far away, and I knew I might not be able to catch up. Even so, I was determined to close the gap as much as possible.

The two bags of KatsuoStamina had a great effect, and the 1,200m climb from there was over in no time, and I was on my way down. My legs were in good spirits, and I was able to hold on. After a long descent, I was finally able to catch the leader in the last 13km or so.

My legs felt only lightly fatigued by the end, and I was able to run the last road section well and finish the race.

The day after the long race my muscles usually ached so much that I couldn't go straight down the stairs. I would walk weirdly, and my legs would swell up like an elephant. But that wasn't the case at all this time: I was very surprised to find that my muscles were taut, but not too damaged. I think KatsuoStamina definitely helped with this.

Takashi Doi🇯🇵Trail Runner

I used KatsuoStamina at UTMF 2019. It is a supplement that I've been taking for some time.
At UTMF, without exception, my legs never gave out. As part of my intake plan, I took two packets before the race, and one packet every two hours during the race. At the beginning of the race, my body was too heavy to run as much as I would have liked, but my body gradually began moving and I was at my best after 130km during the second half of the race.

The rest of the race is a mountainous section, so muscle fatigue and lactic acid buildup in the legs should normally be very noticeable, yet the sensation of lactic acid build up was greatly reduced by continuous intake of KatsuoStamina. I was able to improve my position in the second half of the race, and finished in 8th place despite my poor condition. After using KatsuoStamina, I felt again that it is a reliable and trustworthy supplement that I want to continue to use.
