Some articles on Training to Run Forever include affiliate links to products on Amazon.
If you click one of those links and buy something, this site may earn a small commission, at no extra cost to you. The price you pay is the same either way.
Links are included only when a product category fits the topic of the article. They are never a paid placement, and a commission never changes the advice. When gear is mentioned, it is framed as an option to look at, not a push to buy.
