Hi KK,
Have you read Bud Winter’s book yet? Just asking b/c he used to advocate “foreleg reach” to his sprinters and I see that from your post above and remembering CF’s feelings about stepping over, what Winters suggested sounds counter productive… Almost like overstriding to get a longer stride. If you’re interested I can send you some excerpts on this topic from “so you want to be a sprinter” and tell me what you think.
