im looking to run a fast to start training for a fast 400 this summer. ive seen the clyde hart plan and just came across dwayne millers plan. are their any other good plans out there? also what would be a good rest for the 600 and 300's in this plan? http://www.usatf.org/groups/Coaches/education/specialPrograms/2008/SuperClinic/presentationNotes/Dwayne%20Miller%27s%20notes.pdf
