Ideal race warm-up
Depending on the air and water temperature, you may want to do a brief run to heat up the core.
Do 7–8 minutes of easy swimming, ideally to the first buoy. Stop, take your goggles off and look around. Get comfortable with where the buoys are.
On the way back to shore, continue easy swimming with a series of easy/progressively hard strokes: 30 strokes easy, 30 strokes moderate effort, 30 easy, 25 moderately hard effort, 30 easy, 20 a little faster, 30 easy, 15 even faster and so on. Continue to shore and get ready to race!
