I'm also doing Galloway's plan, but my question is this:
During my short runs, 30-35 min I run the whole time. During my long runs, I'm planning on running for the first 30ish minutes then doing intervals for the rest. Next week I'll be up to 6.5 miles and I did my 5 mile week twice (once at a 4:1, and once running for about 25-30min and finished at a combo of 1:1, and 2:1)
I like the idea of being able to run the first 5 or 6 miles of a half marathon and then falling into a ratio run/walk. This is my first half, I havn't quite found my groove with intervals, I'm just pretty much going with what feels good on the day. But what I'd like to know, before I get into really long runs, is my plan/hope of running for 30 minutes on my long runs (and eventually increasing) then falling into a walk run ratio a good idea? Or should I really be doing a ratio for my whole long run?
