In the 13th training week for 10K racing, most runners move to a new training session.


This web page is based on running 30 miles per week? Go here if you're running 40-60 miles per week

Itís time for most runners to move up a training Phase. It takes beginners
12 weeks to feel comfortable with their 10-12 mile runs, plus 3
miles of fartlek running. These runners will now commence two
weeks of hill training, then move to two weeks of anaerobic
threshold running, and finish out the twenty weeks with four
weeks of short intervals. 
Next time through this training youíll be able to run straight to 6-8
weeks of hill training and anaerobic threshold running; the third
time through, youíll be able to run the short intervals of Phase
Four starting with Week 9 of 20. 
The forth time through, and youíll be so adept at interval running
that you can enter Phase Five in Week Thirteen.

Experienced runners enter Phase Five of 10K Training.

Week Thirteen: Phase Five, but only if you passed the interval test. 
The interval test is simple: Run 12 x 400 meters at 2 mile race
pace, or 12 seconds per mile faster than 5K race pace. Then run 10
miles the next day without feeling distressed. (If you run more than
30 miles per week, run 10 % of your mileage as 400s; follow this
with one third of your weekly mileage as one run...up to fifteen
miles).

Hard running, before you are ready, causes injury.

Phase Five is not for the timid; its training is harsh yet also
stimulating to your mind and your body. It will improve your 10K
time, but only if youíve had sufficient experience with shorter
interval training.
If those 400s, or quarter miles feel gruesome, stay with short
intervals for another 4-6 weeks, then peak for your race. 


400s feel to harsh, please restrain yourself to short interval running

Ready to stimulate your cells?

Longer reps, more intensive interval training for advanced runners. 
Longer reps at 2 mile to 5K race pace place your cardiovascular
and muscular system under high stress for a greater percentage of
your running time. Oxygen uptake and enzyme activity is given
greater stimulation to increase efficiency.

Because you are running fast for a longer distance, you are forced
to run more economically.
Your VO2 max will rise to the highest it is capable of at your
current mileage; your running efficiency will reach its peak;
Your 10K time will improve. Provided that you:
Practice running economically during your long reps.
