TODAY IS A CARDIO DAY. You will continue to build your base today with a 30 min. aerobic session, followed by a cool down (CD) and stretch session for your legs.
WU 10 min.
Run 30-min. Flat terrain, RPE 6.5-7
Training tip: Think about the time you spend on the run rather than the actual miles that you run. This will enable you to become aware of your Rate of Perceived Exertion (RPE) and heart rate, thus use your training time more productively.
