Decathlon Black Friday sale: what you need to know

Decathlon's Black Friday Sale runs from 3 November to 1 December, so you’ve got a decent window to shop, but the better-value bits of kit do tend to disappear fast in your size or preferred model.

The good news is there’s something for pretty much every budget, from cheaper entry-level gear if you’re just getting started, to more serious equipment if you want to upgrade an already decent setup at home.

It’s worth going in with a clear idea of how you’re going to use the gear, because Decathlon’s ranges are more specialised than people give them credit for.

For example, the Domyos strength kit isn’t just “weights”; some benches are designed for progressive overload and barbell work, while others suit lighter, apartment-friendly routines.

The same goes for running shoes and clothing: KIPRUN models cater to very different runners, from stability-seekers to people chasing faster race-day splits.

Stock rotation is constant during Black Friday, so checking back every few days helps you catch new price drops as they land. And since Decathlon often runs parallel reductions in-store and online, it’s worth comparing both if you’ve got a branch nearby.

If you’re kitting out a full home gym, starting Couch to 5K or just picking up a few bits ahead of the new year, Decathlon’s Black Friday sale is an easy way to squeeze more value out of your budget while upgrading the gear you rely on most.
