I like it, very cool. I have entertained the thought of giving middle distance (800m-3000m) another go and see how fast I could go at this stage in life – prompted partially by the same Jay Johnson routines you reference. Steeplechase is another option, though would require quite a bit of work on hip mobility in addition to the explosive/fast stuff. I did notice the location of this year's masters t&f meet, which is a reasonable drive from where I live. I am also excited to be joining a local club as its first masters member and possibly as the masters team organizer/coordinator/coach, with plans to send a team to the meet in Olathe.
