So windy and cold out there that I decided I would run more efficiently indoors on the treadmill. I pushed myself a lot and did a nice 5 miles. On the treadmill I can push myself by increasing the speed. But outdoors I have no good way to gage how fast I am running. So maybe alternating between the two workouts has its benefits. It's still freezing temperatures with a 15-20 knot wind outside here in Deadhorse. That can feel pretty miserable, especially when running directly into the wind.
I hope I can increase my marathon speed this month.
