Where I feel the mid mark chart is absolutely invaluable is for the new vaulter or an old guycoming back to the sport. As a returning vaulter, I am basically coaching my self utilizing everything that I get from Bubba Sparks and you guys and gals here on the forum. Steve White and cdmilton from Flight Deck Athletics have helped me at meets but the one thing they impressed on me was the value of "writing everything down" and "if you only need a 65 foot run up, only take a 65 foot run up". Here's where the mid mark chart comes in. The biggest fear I have is hurting myself while jumping. For an old fossel like me that can happen if I'm under and I rip my arm out of the socket at plant or any other number of things that can go wrong. All of these things go through my mind when I'm at the top of the runway ready to jump. I'm sure it's this way for the new kids too. It can be pretty scary, and obviously can knock the heck out of one's confidence. By working with the chart at all of my end of the season sessions, each time I hit the mid, the confidence level was increasing and , "funny" my jumping was getting better and less painful. If you go to
www.bubbapv.com and go to my backyard set-up photos you can see how I set the runway up for practicing this. I have my tape measure along side the runway. At dj's take off point I have a 8" X 54" piece of packing foam laid across the track.Back at the mid point I have a rope with a loop in it that the tape measure goes through. I play Bubba's face your demons game using the marks and I really feel it's helping me. One thing that no one has mentioned on this thread is you modify per height of the vaulter. I am 5'6" therefore my takeoff point and mid mark is rouhly 4" to 6" out from what's on the chart. I think Dave explained this to me once as what had to be because his published chart is for a vaulter who is 6 feet tall. (Correct me if I am wrong Dave). Anyway, If this document will copy and paste here is an example of what I'm using.

Now to explaine. Each time I'd jump I'd check the take off pad for spike marks. No marks, I was out and ok. Spike marks, and I was under....do it again. This particular day I was creaming the take off pad so I set the pole down and just started running at the pit and diving into it from beyond the pad. Those are the N/H no pole run throughs. On my chart I have a spot to write in whether I hit the pad or not but I had to modify it to fit into this thread format. I have three poles that I use. The Cat is my old 1550 that I chopped and where my grip is, that thing is like using a steel pole. The PUR is my little pole and the SPI is my 150 Spirit. If you look at my mid marks, you will see that they are different than the ones on dj's chart. This is due to me being 5'6" and what dj told me to do. So, here is an actual application of dj's chart. It seems to be working for me.Here are the benefits to me as I see them. Even if I never quite get the 6.40 model down, and I revert back to being a tuck and shooter like I was in high school, if my steps are down and my speed improves (which the chart insists on) I should still be able to do 10 or 11 feet. For an old geezer like me that's pretty good. For a young brand new vaulter, that's pretty good too. If the steps are off, the jump is off. It doesn't matter what a vaulter can do after take off, if the steps are off, the jump is off. Best part about this thread is, because of dj's last post, now I know how to find my start point. Up to this point I was just guessing. I too, appologize for the length of this post, but maybe there's something in there that you coaches and vaulters can use. Later..................Mike
