Learn to swim like an Outdoor Swimmer to reach your bike faster and fresher

March 1, 2018

Outdoor Swimmer, the magazine for adventurous swimmers and media partner for the Castle Swim Series, has set up an exclusive offer for Castle Triathlon participants. Buy their brand new March issue and also receive their two-part Beginner’s Guide to Outdoor Swimming. Learn:

  • How to take advantage of coupling forces to increase your swimming speed
  • How to become more streamlined so you swim faster for less effort
  • How sports psychology can improve your swimming.

The March issue of Outdoor Swimmer is a swim travel special with a six page spread on swimming holidays and how to choose one that’s perfect for you. In the training section we learn how linking the actions of different parts of your body creates coupling motions that enable you to swim faster than using the individual parts alone. We also look at how sports psychology can help your swimming and review the fascinating history of one of the world’s classic long distance swims, the Gibraltar Strait crossing.

Find out more about the offer here.

Hurry! Offer closes on Friday 6 March.
