I purchased this plan with the intent of dropping 10 minutes off my half marathon PB of 1:39. I felt like it was a little ambitious, but I wanted to push myself. Nevertheless, as things go, I got sick a couple weeks into training and ended up having to miss a few other runs here and there due to familial obligations. I still hit about 80% of training, but I was supremely anxious about the race. I knew I could take time off that older PB, but that 1:29 goal really loomed large come race day. On that morning, I missed my start corral due to traffic, and spent the first 5k weaving in and out of the crowd passing a couple thousand people. Eventually I caught some runners more at my pace, locked in and told myself, "just hold this for as long as you can" and managed to bring it home in 1:29:52.
With as many things that didn't go right in my race prep, the fact that I managed to still hit my time goal is a huge confidence boost for future races. I can't thank Ben enough for putting together this plan. It's concise, easy to follow, and forgiving enough if you have to miss some time here and there. It'll push you, but in the best way.
I'm going to lower that goal to 1:25 for my next half, and I don't think I'd have been able to do it without this plan. Buy it and support a guy giving so much to our lovely sport.
