If you're getting ready for Swim Serpentine and aren’t sure which stroke to use, you can choose from four official options: front crawl, breaststroke, backstroke and butterfly. Here’s a closer look at each to help you decide which suits you best.
We carry out regular water quality tests in the Serpentine Lake in the lead-up to Swim Serpentine to ensure we have an accurate and up-to-date understanding of the condition of the water and can give you all the information you need.
