I stuck with the same plan for today as yesterday and very happily found that for all of my 50m reps I was a comfortable second faster than I’d managed only twenty-four hours previously. Even the 25m reps were no slower than yesterday despite feeling quite tired by the time I got that far.
I won’t be swimming tomorrow, but the plan for the following day will now be to repeat the set with the rest interval reduced by five seconds and we’ll see how that goes.
