optimal split differential between 50s in 100

what is the optimal differential between the first and second 50 on a 100 yard short course freestyle? The first 50 benefits from the dive and the relative freshness of the swimmer; the second 50 requires two turns and contending with lactate and fatigue. Is it better to go all out and try to hold on, or save a little for the end? Say you can swim an all-out 50 by itself at 25 seconds. How would you ideally swim the 100? Example: 25.5 then 28.5 for 3 second differential and a 54.0 or 26.0 and 28 for a 2 second differential and a 54. Which method do you think is best?

    Hi Paul, Having seen that your swimming career is newly resurrected...I understand where you're coming from. In my first year back...at age 41...the piano drop on the 3rd turn was inevitable. It was like swimming through concrete. Four years later, the stamina has returned...and I can nearly even split the 100. In due time your dead squirrel feeling will be a distant memory... Until you start doing 200's. :D "It doesn't work for me either. Way off. I'm thinking it's not accurate for yardage slacker masters? Could just be a real underachiever, I guess." At some point the body adjusts to whatever work load you're giving it. Training at a harder interval for a longer duration is tough. But everyone can learn how to adjust as long as the change isn't radical. Sooner or later the interval which seemed impossible gets easier to swim through. That's when the times start dropping. In a way a more challenging workout forces you to swim with economy and effectiveness. ...tighter streamlines, better body posture...more dolphin kicks...Anything that will assist you in picking up a second here and there will have a positive effect.
