As someone trying to decide which plan to use, why do you recommend Higdon over Galloway for a beginner? I'm just concerned about being able to get 6 days a week training in between 3 kids and a fill time career. Plus, the jump from 10 miles in training to the 13.1 race scares me. That's a whole 5K! Thanks for any thoughts.
I haven't used the Higdon, but I do like the Galloway and it has worked for me.
3 days a week has been just fine - 6 days seems like it opens you up for injury, with very few rest days for healing. As a novice I wouldn't do more than 4 running days at most. I tried last year doing way too much too fast (as I mentioned before), and was doing 2 speedwork runs, 1 long run, and 3 cross training per week. It about burned me out, not to mention winding up injured.
Also, I definitely recommend doing at least 11-12 as a long run, and even 14 if you can manage it, especially considering how much time there is between now and the race to ramp up your mileage. It will boost your confidence a lot.
There are more than 20 weeks until this race, so even the folks at 3 miles right now could do as their weekly long run: 3, 4, 5, 6, 7, 4, 6, 8, 9, 5, 7, 9, 11, 5, 6, 8, 10, 12, 10, 14, taper and be fine.
