Hi Kath:
I ran my first marathon in May this year. I had a great time. My training consisted of five 20 milers. I completed the marathon in 4hrs. 10 minutes chip time. I was pleased..I had energy to burn and could have done a better time, but I did not know what to expect with those last 6.2 miles. Anyway, I weight trained 2 times a week. I worked out with Cathe's MIS and PowerHour. I kept muscle tone in my legs and I believe this helped with speed and endurance. It also helped prevent injury. I did lose some definition in my abs but since the marathon, I am training with more weights (heavier) 4 times a week and cardio is a mix of running and step. My mileage now is anywhere from 15 to 20 mpw. (I trained for the marathon at 50 mpw).
As a result of the changes since the marathon, I am getting more tighter in the abs (basically overall). I am going to train this Fall again for some races (5K, 10K and halfMary) and start into marathon training again in January.
Your first marathon is a great learning experience..one in which you will make mistakes, but you will learn to "tweak" your training with each new experience to better yourself. Stay focused and you will accomplish so much!!!!
God Bless,
Marla
