Ok, I'll break down and admit it -- I'm an engineer. The weak point in the "reach for the dash" system is your abdominals, and you're essentially doing a single situp. How much weight can you carry on your chest while doing situps? Assume that you're lifting about half of your body weight, so if you can do a single situp with (in my case) 80lbs on your chest, that'd be like reaching forward under 1G of acceleration. Calculate the acceleration based on the given times, then go to the gym and take some data.
