C25k marathon training

I am following this c25k training schedule to possibly train for a marathon? 

What is your opinion ?http://www.coolrunning.com/engine/2/2_4/130.shtml Is this a good training schedule or could you recommend a better one?

 When I first began running I used that program. Then as I started further distances like a half marathon and full marathon used a training program by Hal Higgdon.   Whichever you choose good luck on the road  

I only trained 3 times a week for my marathons or any race and that is including training for my ultra. I would like to see some temp runs in there and some strength training those two to me are so important. Good luck
