1.5 miles
I noticed (after I bought it

) about the 40. Next year we have a thing on base where we can compete in 50-400meter dashes, so I'll deffinately be spending more time with this training than for now. But have had some trouble really finding information for training for 1.5 miles...especially when you have 6 or so months to get there!
I had just thought that doing a month or two of this type of speed training might help develop a stronger plyo base a bit and help with the relative strength\stride length enough to be benificial when I switched gears and started stretching the distance out.
It's my lame attept at periodization for the short distance run and trying to condition a little better to handle the 200-800 repeats when that time comes.
