Top Tips for Beginners:

Before you join your first open-water swim event, follow these tips to help you prepare:

Train in Open Water: Practice swimming in lakes, rivers, or the sea to familiarize yourself with the conditions you’ll face during the event. Always check the water conditions, use a safety buoy, and train with a buddy.

Wear the Right Gear: A well-fitting swimming wetsuit keeps you warm, while goggles designed for open-water use help with visibility and glare from the water.

Learn to Sight: Practice lifting your head to spot landmarks, as open-water swimming doesn’t have lane lines to guide you.

Start Slow: Position yourself at the back or side of your wave to avoid the initial rush of swimmers and settle into your pace.

Stay Positive: Focus on enjoying the experience and the scenery, rather than worrying about speed or performance.
