5 days a week of training and two days should be dedicated to testing in this program.
That is, practice two days a week under real test conditions On the rest of the training days, run 5000 meters in intervals.
Interval should be with rest in between and with low intensity on recovery days and high intensity on other days.
Consume enough water, fruits, and vegetables well. Of course, the best plan is to monitor individual attendance.
Good luck
