Hills
When you start adding hills to your Monday workouts, be conservative.
Start with just a couple of short hills (200 meters) and add another
hill every week or choose hills that are longer in length (800
meters).
Multiple Workouts
There are several days that include multiple workouts in one
day. This is designed to simulate running 3 legs over 24-hours.
You may also try running at night and at high altitude.
Food and Hydration
While training you should practice re-hydrating and eating as
if you were actually running a relay. Choose replacement drinks
and foods that are easily managed by your stomach: high in carbohydrates,
easily digestible, and easily transportable.
