I am a 14:50 and 31:00 guy and have averaged around 70 miles a week since January. I have recently run a flat 15k at under 5:20 pace and had trouble at the end. I will be running the philly half marathon in November and want do to really well. I feel like running a good half will not only give me confidence for a marathon later on, but the training will set me up to have a good outdoor track campaign in my first year as a post collegiate. I would like to be in the 1:07-1:08 area but I really don't know how to get there. The race is in 17-18 weeks, so I was wondering if anyone had any specific advice or training logs that I could look at. I know how to train for the shorter races but I have no experience with the longer ones. I could use a coach, but I don't really know anyone who could help me so I am turning to letsrun. What do you suggest?
