I have always felt that in order to get to a 5K distance that I should run for the majority of the time i.e. 30 mins non stop running. I usually do a 5min warm up walk, run, then have to have a much longer cool down walk. Today I mixed it up a bit and started with a 10 min warm up walk, run for 15 mins, 2min walk etc and I completed the 5K 16 seconds quicker than I have before. Sorry for the rambling post, but my question is, is it ok to break up my run with a couple of little walks? For some reason, I feel bit of a fraud doing this. Advice anyone?
