Hey Wisconman,
So do you 4 step during meets, since you have to reach with reduced distances?
Regardless, I would start the season with the spacing even closer than just 1 foot in. Depending on what your goals are for your splits and what you are capable of spacing them and being able to be quick and not reach in between and then working toward moving them further out as the season goes.
As far as bringing them in 1 foot each, I have never had a problem with my hurdlers when they have gotten to meets after reduced spacings. I personally do not run many work outs with the hurdles at normal spacings, just because it’s harder for my athletes to hit the desired splits we are working towards.
In terms of being able to finish a whole flight of 10 hurdles without reaching, why not set up something where you run 8-12 hurdles and gradually bring them closer as you go.
For Example…H1-H3 @8.2m, H4-H6 @8.0m, H7-H8 @7.8m.
