You know the type. There's a medal rack in the garage, a drawer that holds more compression sleeves than socks, and a tan line where his watch sits that no beach vacation has ever erased. His idea of sleeping in is a 6am shakeout run. Buying for him is easy in theory — he clearly likes running — and a minefield in practice, because he already owns the obvious stuff and has strong opinions about the rest.
The trick is knowing where the gaps are. Runners pour money into shoes and race entries, then run themselves into the ground on recovery gear that's a decade old and safety gear they keep meaning to buy. That's your opening. He'll never spend on the boring, unglamorous stuff for himself — which is exactly why it lands as a gift.
Below is a spread across every price point, from a ten-dollar tube of anti-chafe balm that'll save his marathon to the compression boots he'd never justify buying. Match the gift to the runner: the data obsessive, the pre-dawn road warrior, or the guy whose calves are held together with tape.
