Skratch Labs is the Official Nutrition + Hydration Partner of the San Francisco Marathon, and we’re here to help you get it right. Below you’ll find a collection of articles from our team covering everything from race day hydration strategy to what to eat the night before. Read what’s relevant to your distance, experiment in training, and head to the start line with a plan you’ve actually practiced.

Try Skratch for free before race day. Your gut will thank you.

Race day isn’t the time to try something new. The best nutrition strategy is one you’ve tested in training, dialed in on a long run, and actually enjoy consuming when you’re working hard.

That’s why we’re offering first-time Skratch customers a free sample pack of our best-selling hydration, fuel, and recovery products. Just use code SFMSAMPLER at checkout and pay shipping, that’s it.
