Intervals - should I be phasing them out?
Hello all,
I am newish to running - I began in January of this year and have been making steady progress with a bit of a plateau this summer because of the heat and vacation. I am starting to refocus and I am wondering about intervals - pretty much all my runs except my really short ones (1-1.5 miles) feature a few 3x7 or 2x8 minute intervals because it helps me keep my heart rate down. My longest distance up to this point is 4.5 miles and I am aiming to do an 8K in November. I have been trying to go slowly and carefully so I don’t injure myself and am also strength training.
My question is - should I be phasing out walking? Even if my overall pace is almost always faster if I have at least a few minutes of walking here and there? Like, with intervals I tend to hit a steady 12 minute mile and my average time for a 5K is about 39 minutes which seems fine? (I’m not trying to be a speed demon or anything) but I’m just wondering if I should be trying to get it so I can run all the miles without a walking break?
