When I lived in Seattle I would run outdoors unless it was pouring rain. Many a day I ran in the rain, wind, sun and snow. Now that I live in the desert running outdoors becomes harder in the summer as it is just too hot. Preparing for a half marathon is even more challenging. I am now doing something I did not do in my previous two races, I am training on a treadmill.
The treadmill does have some advantages as it forces me to keep a certain pace. When running on my own I can slow down as I get tired. The treadmill keeps me going at a steady pace. I will incorporate one or two runs in the early morning or at night so that on race day I am prepared to run on the hard surface.
It will be interesting to see if working on the treadmill increases my pace or not. I will time my runs once my program has me run 3,2 miles as I have run that distance often and know what my general pace is.
Cross training is also an important part of preparing for a race. Cross training prevents injuries by working muscles in a different way than your normal activity. For my cross training I will be riding my bicycle and swimming laps. Both of those activities are easy on the joints as opposed to running. I will be taking today off to allow my muscles to recover. Have a great weekend!
