400m Time Trial
I only started swimming in June, last year, and am really happy with my progress having just done my first sub 8min 400m (7:57).
However, when I swim 400m I, unintentionally go off quite quickly 24sec/25m which means I'm slowing down considerably towards the latter stages.
My question is, should I continue to swim as I am and my fitness will improve so I maintain the quicker pace for longer, or should I try to slow my initial pace and maintain a quicker pace overall? What have others done?
