Intervals Vs. No Intervals

I was talking to my buddy about the marathon training the other day about running intervals. He only runs without walk breaks, I was trying to convince him otherwise. He says he feels like he has given up if he stops to walk. OK, we'll see how long that works for him...

Anyway, per my usual engineering mentality I did a little test of my own. Disclaimer: this is only two data points under not exact conditions so yeah it may not always produce the same results. There are lots of variables. But its a start.

Run 1: Saturday 8/4 8:52 PM No Walk Breaks 44:31 3.80 mi 11:42 min/mi
Run 2: Monday 8/6 8:32 PM With Walk Breaks 44:48 3.89 mi 11:31 min/mi

So, not that much different in time... slightly better with the breaks. Mentally I was thinking I could run harder since I had the break coming up on Run 2. I was always trying to conserve on Run 1, but that is also the furthest I have run with no walk breaks... so there is lack of experience there.

Anyway, I plan on keeping the breaks for the most part and just extending them longer... to say one mile. It would be nice to just run between the water stations in a race.
