Description
Description
Katsuo Stamina is a Japan-made tablet built on a bonito fish extract, and it has one thing most race products don’t: a separate schedule for each sport and distance. A half marathon is one dose before the start. A long trail race is a dose before, then another every 90 minutes until you finish.
What it is
- Made in Japan from bonito, the fish known as katsuo
- Tablets taken with water, easy to carry in a pocket or zip bag
- About 6 kcal per 4 tablets, so it sits alongside your fuel rather than replacing it
How to use Katsuo Stamina
Take the tablets with water, 30 minutes before the start, then follow the schedule for your event:
- Half marathon: 4 tablets before the start.
- Marathon: 4 tablets before, then 4 every 120 minutes until the finish.
- Ultra marathon: 8 tablets before, then 4 every 120 minutes.
- Trail 15 to 30 km: 8 tablets before the start.
- Trail over 30 km: 8 tablets before, then 4 every 90 minutes.
- Cycling or climbing: 8 tablets before, then 4 every 120 minutes.
- Swimming or rowing: 4 tablets before, then 4 every 60 minutes.
Follow the product label. Set a watch timer when you take the first dose so you don’t lose track mid-race.
Plan the rest of your fuel
Katsuo Stamina doesn’t replace carbohydrate, fluid or electrolytes. Get those right first, then add it to the plan and rehearse the whole thing on a long training run.
Allergen information
Contains bonito fish. Unsuitable for anyone with a fish allergy.
Common questions
How many tablets do I need for an ultra?
Count from your expected finish time, not the distance. A 10-hour trail 50 km is 8 tablets before the start plus 24 on the course. We worked out common race times in Katsuo Stamina for Ultramarathons.
What exactly is in it?
A bonito fish extract built around peptides of beta-alanine and methylhistidine. The full label is broken down in What’s in Katsuo Stamina?
Can I take it with gels and Elec Stamina?
Yes. They do different jobs and sit side by side in a long race plan.
Is it a BCAA?
No. BCAAs are three single amino acids. Katsuo Stamina is a fish extract. See Is Katsuo Stamina a BCAA?
Does it count towards my sodium?
No. Its sodium content is negligible, so plan your sodium separately.
