if u will be competing until may then id suggest u stop ur heavy weight training atleast 3weeks before ur first competition in february and start converting to power. i would suggest then on ur high intensity day u do ur sprints followed by a complex session that includes a mix between plyos and weight training (power all the way so reps are low and rest is enough). then do the lighter tempo session the other day. u can start using ur spikes to get a feeling of the track and work ur speed. start off with 60m to work on good acceleration and work ur way from there to top speed, speed endurance, and special endurance. work hard and train smart.
good luck
