Week 2 of marathon training

I'm following a marathon training program I found on www.marathon-training-program.com I chose this program mainly because of the 3 run/week commitment and designed for runners who just want to complete. I'd like to train more but that is not possible right now. I'm doing okay on the longer runs but not so good on any kind of speedwork. Have never enjoyed speedwork so hence, never do it and never run faster. Might need to get some help with that.
