Thank you everyone. You're confirming what I thought. I did a lot of Ow with a wetsuit as training and almost no pool training and so the legs thing must make the biggest difference for me. I will defo try to keep my hips up so any other tips would be great.
im doing a lot of pool swimming in prep for an IM whereas last year most of my swimming was in ow last year. I am seriously slow in the pool like 1:05 for 50metres but managed a half IM in 34 last year. what other factors other than the wetsuit mean I'm so slow. obviously technique is an issue but I am as cardiovascularly fit as I have ever been but feel like my goal of a 1hr hm swim isnt going to happen if im currently doing 2.5k per hour at the moment?
