Ran 18 mi long run at the Olympic Oval to get heart rate data and to stay out of the inversion. Went easy at 7 min pace for 3 mi then started 12 miles at marathon pace-5:54-5:58/mi. HR-148 bpm. Legs felt kind of heavy today. I need to increase caloric intake of carbohydrates. After 8 mi things started to feel a little better. Picked up the last 2 mi at 5:44-5:46/mi.with 152-154 bpm. Heart rate stayed remarkably stable with out much drift at the end. Was tempted to wear racing flats but with this much mileage wearing them might bring on an injury. Im beginning to go into uncharted territory mileage wise especially if I stay consistent. Being the case I must pay attention to details now more than ever. |
