Where are you now with your event performances? Is track and field new to you?
These are the most useful articles I've found:
Basically, your training should be:
4-5 days a week of technical training (2-3 events) + a running workout
eg. Monday: pole vault, discus, 400m (2x2x300m, 1' & 10')
2-4 sessions in the gym: cleans, squats, snatches, deadlift, push presses + core/ancillary stuff
2-5 sessions of other training: plyos, gymnastics, med. ball stuff
Obviously, if you have access to coaching, you will be much more successful. Coaching is usually in the evening, so head to the gym (don't tire yourself out here) in the mornings and go to the track at night.
