What else are you doing? How fast are you currently? What is your target time?
I’d be spending a lot more time on an acceleration progression 2-3x per week at the early stages of the season.
IE – 12x15m then 12×20 then 12×25 10×30 and so on. As well as hills, resisted runs, etc.
I would also spend a lot of energy on doing tempo runs – 100-300m at slower pace to simply get the running volume in – and that will do a lot for your speed as well. Don’t think you need MaxV right now.
When you do MaxV – I’d like to see it start with longer acceleration runs out to 40, 50, 60, 80m before doing flys. Then doing Sprint Float Sprint runs (20-20-20 – 30/30/30 – 40/40/40) then moving into MaxV where you start with 10m flys, then 15, then 20, etc.
And one of your tempo days being fast 100-150m runs.
