Actually, I do three times per week, one time I do both sprinting and lifting in one day, otherwise i do weights sep. from tempo work. Even tempo is about 1500m per session, not much. later in preparation I add 50’s or 70’s to the acceleration session. ex. 5x30m, 2x70m, or 4x30m and 1x300m. that’s it.very simple. I would like to doi more work but I am limited to my body- not young any more… 
Right now I changed a little bit my lifting session- more volume work, I will see what happen in a couple of weeks when the comp. season will kick off…
