My own experience was that in doing intervals, say 8x500, with a 12 warm up as recommended for TR work, my second and third intervals would always be faster - and easier than the first. My conclusion was that I wasn't getting enough warm up. I have regularly used the EF wu for 2k time trials and races, but never for training workouts. I have also used it for 1k and 500m time trials. As I said in a previous post, I think that those shorter pieces probably should have an even longer wu, but mental laziness led me to just stick with the EF.jackarabit wrote:Bob, for the short interval workouts of 3.5 to 4k total volume, I omit one 4' segment from the Fletcher Warmup. Total last time used, 3070m at my paces, conforming to the Marston prescription for speed interval warmup in the lunch hour blog, including the bursts of higher pace. I have no doubt you are correct as to Mr. Fletcher's intention. Historical awareness and critical rigor are at the service of all who honor truth, fair play, and credit to him to whom credit is due. Thank you. Jack
