30 Minute Swim
How far can you swim in 30 minutes?
Already swam the 1km Challenge? The 30min Swim is the next step up in testing your endurance fitness. It's the half marathon of pool challenges.
Please note: you must take splits for every 100m you swim. It's just too easy to lose track otherwise. You can either have someone record your splits, use a watch that can record all your splits, or record video of your swim and take your splits from that.
