Have you ever thought about swimming the english channel but figured it was simply too far or too much cold water for too long? Want to swim the channel, but the 34K is just a little too long? How about a relay??
Below is a link to a flyer I heard about through effortless swimming. It talks about a swimming coach that has quite a good plan as to how to gather teams together to do the english channel in a relay! I have listened to her podcast where she talks about this method, how to do the training with people in different locations and how to do the qualifications.
So, if you have been thinking about it, this could be a stepping stone!
