In reply to ice.solo: That like all your responses makes so much sense, and now I'm almost ahead of you in knowing it.
Might try the 4-6-8-4 pattern to see what it achieves.
Like watching good climbers I know I will learn by watching swimmers and trying to copy
Occasionally i find the envelope of effeciency just need to know where it is rather than stumbeling on it.
Exhaling underwater yep already knew that, head position (tilted slightly further forward gives me a better breath draw, so working to that.
Legs are useless noted!
Was considering, maybe with all the climbing my arms and shoulders are strong but not areobically fit, I need to work on that like I have my legs this last year.
Oh and did a new PB for 5k tonight felt great. dropped 30+sec of my previous.
And yep I have done it with running so I can do it with swimming. Felt crap going to the pool on Saturday but managed 10 crawl (resting every 2 lengths) 10 Breast, repeated then two fast crawl. 1.05K
Tri club training tomorrow
