I tend to do a mix of events; fell running, triathlon, TTs (bike), aquathlon, duathlon so the training plan reflects that - Its also winter so I've got the higher risk strength and technique workouts in there (summer tends to focus on strength maintenance and VO2 Max work in between races).
Monday: fasted bike ride to work (10km), Masters swim session (1hr), Ride home with 10x 30s Sprints with at least 1 min recovery between each (approx 20km)
Tuesday: Easy school run / ride to work (11km), 20km ride home with middle 30 mins just over FTP (TT simulation), 'Max strength' weight training - mix of 5 sets of 5 reps (last to failure) of full body exercises e.g. barbell deadlift, barbell squat to shoulder press, barbell lunge, core strength exercises, injury specific exercises (for achilles tendon and ITB strengthening/compensation). Group run (7km) inc. 5x 30s sprints with plenty of recovery
Wednesday: Rest day - cycling school run but keeping HR < 100bpm
