If you follow the Vanc 04 SPP then take it out to 120 in SPP 2 (spring time) it should work. You could even do a SPP3 out to 150-200m (look at Ben’s 87 yearly plan)
Im going off of my own instincs not just Ben’s plan… I think I messed up this year doing only 120s I should have gone farther than 120s. Even though I improved 1 sec in the 200 I think I could have done more. After I PRd in training for the 120 I started to do only short stuff. After a few weeks of not doing the longer stuff I started to feel a bit more tired at the end of the 200. Even though I was well rested before the meets… So Im def going to try and go out to 200 after I have a nice 120 in place.
