The Deep Dive Digest is the weekly news email. It gathers the significant sports technology stories from the5krunner into one edition: the leaks, the launches, the lawsuits and the industry moves, sent free and without ads. Read it when you want the week’s news in one place rather than story by story.
The Deep Dive Fix Files documents what went wrong and how to put it right. Each weekly issue states a sports tech fault, the hardware or software affected, and the best fix or workaround the endurance community has found, with a topic index covering the whole archive. Read it when a device is misbehaving and you want a known solution.
