I am an experienced runner recently starting triathlons. So far I am not able to do freestyle for more then a couple of minutes (althou I can do breast stroke for hours).
My recent training was quite successfull getting me to freestyle: The last few times did
10 x (50m + 60s rest)
Now I wonder how to proceed. Should I try to do 75m in each repetition, should I try to reduce the rest, or should I try to increase the number of repetitions?
My ultimate goal is to be able to swim 1000m freestyle, as soon (not as fast) as possible. Having the perfect style is secondary, I try to apply the pareto principle and get as much progress out of my training as I humanly can.
