It's the last day of #SummerTimeSwim, so don't forget to upload your results!

Well done to everyone who took on a swimming time challenge this month. We hope you've loved clocking up your hours! ⏰

It’s about TIME, not distance.

Whether you're at the pool, the beach, or a lake, the goal is simple: swim as much as you can throughout August.

Challenge yourself or compete with friends and family!
