im just curious of where the predictors from 30m comes from. because on my journal its said that a 4 flat off first movement for 30m is well sub 11 for the hundred, but if you take 4.00 for the first 30m, .15 for RT and then take a speed of 10 m/s (probably about what the fastest hs kids run at least) and assume perfect se, that still adds up to 11.15. seems like the charts are very sweked towards those with good top speed and not so good a start,eh?
I think it’s a bad idea to rely on 30m timing for anything but 30m times. I’ve been timed at 3.98 from first motion and I run 12.5 FAT!
If you want a more accurate predictor of 100m speed, as stated above the further you go the better. I find that a hand timed 150m is a very accurate predictor of 100m and 200m for me- I’m not saying it will work for you, but it will be much better than trying to extrapolate 30m times.
Now, if you’ve only been running 30m accels in your training, I’m not suggesting you go and blast off a few 150’s, because that will definitely screw you up. I’ve noticed at least in the south here where I am for the summer, there are a surprising number of open meets that run outdoor 50’s and 60’s. If you haven’t been going really far in training, that could be a safe way to get at least an idea of your FAT times without perhaps exposing you to injury risks.
On a side note, Ku2u was kind enough to lend me his Freelap for the past couple of weeks, and it is frighteningly accurate. They are expensive, but an invaluable tool for those training alone, especially if you have the touch pad button and at least two timing stick thingy’s, that way you could get your 0-30m time, plus say a flying 20m split or flying 30m split. Trust me, you may be appalled by your actual 20m split, but at least it will be accurate. Very useful!
If you can’t spend $500, I’d say mark out 30m with a couple of waist height hurdles on the track, get someone to videotape you, and import it into Windows Movie Maker. You can get within 0.03 at 30 frames per second, then you can round up.
Many high school football players can run a 4.25 sec 40 yard dash if their dad has a good stopwatch and a slow thumb.

i have to assume your a bigger guy then, that seems like a very large discrepency between start and finish
I’ve ran several 3.8x handtime 30m from first movement and with a brower system I ran 4.18 from touchpad and still couldn’t break 12 earlier that same year/summer. I’m 5’10, 175lbs.
That sux… That Frank Dick chart only works if you can get the 30M time FAT…I’ve tried it every which way and this is the only way I can get any real times.
For those who dont have the testing chart here it is in spread sheet format:
I’ve timed quite a few girls in the 3.50 to 3.80 range for the 30 meter fly using automated timing equipment (Brower and Freelap), and based on my experience, the 100 meter competition times are a tad low.

I’m tall, but that’s not the point. The point is, your 30m time will tell you how fast your 30 is, and that is IT. You need to stop obsessing about mom-timed 30’s and work on the rest of your race.

This is a compelling question. If you are serious about your training, it requires a compelling answer. How can you measure progress if you can’t measure? What is the point of keeping detailed records if you don’t have accurate details to record? How can you assess your training program if you lack the tools to assess? Once you have answers to these questions, you will have a better idea of where you are and a direction you should proceed.

haha, ive never had my mom time a 30 for me. that’s the other guy. i’m just wondering bc my college runs a 30m test in the fall and im not sure what a good time for it would be
and your 30 still definitely can say a lot about your speed, no one who is really fast will have too awful a 30, though i guess vice versa isnt as sure (the same fast people are strong, but strong people arent necessarily fast type of idea)
by FAT do you mean electronic timing off first movement or timing with rt factored in?
The chart is off in some places. The USATF Level 2 chart is a bit better. Not perfect but better.
That’s a good question. I’m also confused at how Angella Issajenko, according to CTFS (page 141), can run blistering 3.5’s, 3.7’s 30m sprints and (respectfully) can only come in around 7.1 at the 60m. She did dip high 6 seconds for the 60 but I would think if you can run 3.5 that’s guaranteed 6 seconds anything all the time for the 60m.
Or do I not make any sense?
Thank you ^^ Lots if info in this post. And it’s funny you mention the 150’s as I have chosen to run a 150 instead of the 200m. I going to run the 150 over the weekend. I would have ran it last week but I was not able to recover like I wanted.
I thought about that too when I was reading charlie’s manual. It was hand timed that could be why she ran sick times (could be other things too) I think that year she ran 3.5 her 100m time was 11 low or something… But then again PJ told me that olusoji fusaba can run a 3.4 from the blocks… So I mean it could be the person timing or whatever who knows…
I dont think you can really get anything from these charts unless you have fancy timing equipment and factor in reaction time. If you really REALLY want to know what you are capable of you need to go to a meet with FAT.
+1 Will do.
I think its been mentioned numerous times in other threads but one always needs to be cautious regarding hand times. Hand times are for your own comparison. It allows your coach or you as your coach to compare your athlete against other athletes in the squad or against themselves to gauge improvements. It doesn’t matter if one gets a 3.4 or a 3.9 or a 4.5 as its relative to their timing set up. Its important to remember that 30 times mentioned across squads can be timed in different ways…first step, first movement, walk in, standing, crouch, 3-point, off a gun etc etc all with different timers. there are enough variables there to result in numerous 30m times for the same person let alone making comparison to other peoples numbers. The 30m tells you how your 30m is going…in looking at speed tables it provides some insight into what one could run assuming other factors are in play such as MV and speed end. It also provides you with insight into rough times one needs to run to produce world class performances. It doesn’t however cater for outliers which exist in every sport. If you have an athlete who is recording 3.9 on your time for 30m hand timed and they are running 10.30s electric then that gives you info and any subsequent movement in this time may impact on the overall race time. Finally always remember that some of the best can find improvements in time from training when they step up because there training is focused on good acceleration mechanics under control and thus they may reserve that 1% for race day…
^^ You’re points are noted. Thank you Spike.

with RT. the only system I was accurately able to verify those charts was with the finishlynx reactime with the hard wired tripods. I ran a 4.4 30m wich was on the chart was 11high and is what I ran that year… This was a few years ago.
