Thanks Evg.
What we’ve been doing is after a fail he swims 25 easy off the same turn around then goes again.
On his last set he did 43 reps total including 2 fails (and so two “easys”) so he did 39 at target pace (14.0 or better) – this says to me we need to drop his time. I wonder if going to 13.8 is fast enough – 22 of his 49 reps were faster than 13.8.
We might try 13.8 and see what happens. If it’s too slow (i.e if he does at least 20) we can always drop again.
Thanks for the sprint link. I was wondering how you do USRPT for 50s!!
