We use the 2IM splits for all IM work as well. We’ll start with 25s at ½ IM split for that leg and work to 50s later in the season.
Early: target time is ½ 2IM split
10 x 25 fly
15 x 25 ba
20 x 25 br
25 x 25 fr
We’ll then rotate in the 50s with the exception of the fly, always seems to get just too technically unsound.
Mid season
20 x 25 fly ½
12 x 50 ba using 2IM split
30 x 25 br ½
14 x 50 fr using 2IM split
Or
20 x 25 fly
30 x 25 ba
12 x 50 br
14 x 50 fr
By the end of the cycle they should be able to handle
30 x 25 fly
14 x 50 ba
16 x 50 br
20 x 50 fr or 8 x 100 fr @ 2IM split times 2
