I see a lot of newer and not so new runners here bemoaning their lack of speed..well, just to put that into perspective - do you walk as well? I do, I walk on my own and I walk at Parkrun, either as Park Walker, or Tail Walker, and when did you last hear anyone complaining about their walking speed? Never is my guess, so why worry about your running speed?
I blame Laura, telling us right at the beginning we will cover around 5K in 30 minutes. I've never even come close, not in 9 years of running. Nor is my walking pace 4 MPH, never even come close to that either.
Exercise is great, that's the important thing, not how fast you go. Especially for races, why pay all that money then use up all the fun so quickly? I get more value for money than the racing snakes!
